In the automotive world, there are many myths about engines that do not break. These legends are rooted in the confrontation between German, Japanese and American engine builders. But most importantly, these "fairy tales" are not really fairy tales. "Indestructible" motors have long been among us.

Gasoline "fours"

The most common "fours" can boast an enviable life expectancy. This is especially true for three motors that are rightfully considered legends.

Mitsubishi 4G63

The 2-liter engine appeared back in 1982. But even now its licensed copies are assembled at factories, not only in Japan, but in China.

Initially, the power unit was equipped with only one camshaft, and there were three valves per cylinder. This version was called SOHC. Five years later, a new variation appeared with two camshafts. She received the name DOHC.

Various modifications of this engine were installed not only on Mitsubishi, but also on Korean Kia and Huyndai. Now the “Chinese” Brilliance is busy with the production of the veteran.

Toyota 3S-FE

The 3S-FE engine is considered one of the most reliable and durable. For the power units of the 90s, it was quite ordinary: four cylinders, sixteen valves and a 2-liter volume. The number of "horses" varied from 128 to 140.

This unit was equipped with the most popular models Toyota. For example, Camry from 1987 to 1991, Carina from 1987 to 1998, Avensis from 1997 to 2000, RAV4 from 1994 to 2000.

With good and timely service motors can easily “run back” 500,000 kilometers without major repairs. And there will still be a margin of safety. A distinctive feature of the 3S-FE, in addition, is good maintainability.

Honda D series

These motors stopped producing exactly ten years ago. But in twenty-one years of production, they have proven themselves from the best side.

There were about a dozen different variations of the power unit, with a volume from 1.2 liters to 1.7. Power reached the "herd" of 131 "horses", and the working speed was approaching the mark of 7,000.

Equipped with these engines Civic, Accord, Stream, HR-V and "Akurov" Integra.

Before the overhaul, the engines "lived" 400-500 thousand kilometers. And the thoughtfulness of the unit allowed after the "reincarnation" to run back about the same amount.

Petrol "sixes"

Among these engines, there are also quite a few long-lived heroes. Just a simple enumeration will take several pages of text. Therefore, we will focus on the most popular pair.

1968 is known not only for the XIX Summer Olympic Games in Mexico City and the loss of the US Air Force in Greenland of the atomic bomb, but also for the birth of legendary motor M30. AT different options it was produced until 1994.

Engine capacity varied from 2.5 to 3.4 liters, power - from 150 to 220 "horses".

The secret of reliability lay in the classic design of the motor: cast iron block, timing chain drive, 12-valve block head - made of aluminum. The M30 also has a turbocharged relative - the M102B34 with a capacity of 252 "horses".

Equipped with M30 engines, cars of three series at once: the fifth, sixth and seventh.

And now in BMW sales ads you can find cars with this particular power unit. And a run of 400,000 kilometers without major repairs is a worthy indicator, but not the limit. M30 can plow all 500,000.

Toyota 1JZ-GE and 2JZ-GE

These Japanese engines have been produced for 17 years, from 1990 to 2007. The first is 2.5 liters, the second is 3 liters. They also had supercharged modifications under the indices 1JZ-GTE and 2JZ-GTE.

In our country, these power units received most widespread in the Far East. After all, it was there that the most “old-school” right-hand drive “Japanese” were listed.

Such motors were equipped with Supra, Chaser, Soarer, Crown and Mark II, as well as GS300 and Lexus Is 300 brought from America.

The resource of engines from the Land of the Rising Sun is truly enormous. There are cars whose motor honestly worked for a million (!) Kilometers before going for overhaul.

Diesel centenarians

Diesels were originally famous for their reliability. Moreover, the first generations of power units operating on “heavy” fuel had a more or less simple design, and therefore a serious margin of safety.

Mercedes-Benz OM602

Stuttgart engines were produced from 1985 to 2002, and did not cause any complaints. On the contrary, their reliability and durability, regardless of mileage and operating conditions, have given rise to many legends.

In technical terms, they are simple: five cylinders, each of which has two valves, and an in-line mechanical fuel pump high pressure from Bosch.

By the way, the motors did not differ in power - they gave out only 90-130 "horses", depending on the variation.

They were put on the W124, W201, G-class, T1 and Sprinter models. Found them and more new model W210.

With timely maintenance, engines can easily withstand a mileage of a million kilometers before major repairs. And if you believe the legends, then the OM602 is able to run back even 2 million.

For ten years - from 1998 to 2008 - these engines were put under the hoods of almost the entire BMW line, from the 3rd series to the 7th. Their power ranged from 201 to 286 "horses". By the way, they came across in the English Range Rover.

A distinctive feature of the M57 was the amazing dynamics for a diesel engine. Cars equipped with this engine simply broke the stereotypes about power units on "heavy" fuel. For example, the 330D model (E46 body) was perceived as a real lighter car. Therefore, most often it was bought by fans to drive. And high reliability and maintainability only added pluses to the car ...

Almost all modern gasoline engines have a very complex design, thanks to which the engineers who worked on them manage to achieve excellent environmental and power performance. But if many power units, despite this, can withstand a run of 200-250 thousand kilometers without any problems, then individual copies begin to present unpleasant surprises much earlier. So what modern gasoline engines deserve to be called the worst in terms of reliability today?

Engines 2.0 JTS and 2.2 JTS Alfa Romeo

Without a doubt, this list includes 2.0 JTS and 2.2 JTS engines installed on Alfa Romeo cars. These power units can be found under the hood of the 156, 159, GT and Brera models. Both engines have one common problem- carbon deposits on the intake valves. In the case of a power unit of a smaller volume, it can even come to damage to the valves. And 2.2 JTS is characterized by accelerated wear camshafts. In addition, both power units are prone to excessive oil consumption. Periodic failures in the operation of control electronics are not uncommon.

Toyota ZZ series (1.4 - 1.8 liters)

Excessive consumption of oil affects and ZZ series engines (1.4 - 1.8 liters) from Toyota, which were born in 2000 and were installed, for example, on models Corolla Verso and Avensis. Due to a design miscalculation, not all parts of the ZZ family engines receive the required amount of lubrication, which often ends in very rapid wear. piston rings. Fortunately, the Japanese still tried to solve this problem and used an additional oil channel in the modified engines.

Petrol engine 1.6 THP Peugeot and Citroen

It didn't turn out too well and 1.6 THP petrol engine, which the French from Peugeot and Citroen designed together with specialists from the German BMW. Initially, this power unit, but it was installed on the BMW of the first series, Mini Cooper S and almost all modern models concern PSA, has earned a lot of flattering reviews. However, then it became clear that this engine is prone to premature wear of the camshaft bearings, which, moreover, can accelerate even more during long driving with reduced level engine oil. Add here the malfunctions of the electronics and the valve timing system. But that's not all. Quite often, damage to the turbocharger rotor occurs in 1.6 THP engines. And the worst thing is that all this happens at a very low mileage. Against this background, the problems with the stretching chain of the timing mechanism no longer seem so significant.

Engines of the TSI family (1.2 and 1.4 liters) Volkswagen

The chain is also stretched in the engines of the TSI family (1.2 and 1.4 liters) from Volkswagen. And if you do not rush to replace it, then it is quite possible to get to the overhaul of the engine. In addition, in TSI engines due to a defective valve, problems with the turbine are often observed. And on some cars, cases of piston burnout were recorded at all. Volkswagen, however, responded very quickly to the problems that arose and already in 2012 introduced new version motor (EA211 series). In it, the timing chain drive was replaced by a much less problematic belt.

Three-cylinder gasoline engine 1.0 R3 Opel

Well, the most unfortunate this moment can be recognized three-cylinder petrol engine 1.0 R3 from Opel, which was installed on the Opel Corsa C and Agila models. Not only is this power unit notable for its rather rough operation and low power, it is also one of the worst in terms of reliability. Failed ignition coils and an engine control unit, oil and coolant leaks are far from all that owners of cars with this power unit under the hood have to deal with. For some of them, it all ended with twisted liners and a broken timing chain. A certain minus of the 1.0 R engine can also be called the fact that it was installed exclusively on available small cars. As a result, now the cost of overhauling such a power unit may well exceed the cost of the car itself. There is something to think about!

Production: since 1993 - 1.2 liters, since 2003 - 1.4 liters.

Application: Fiat Punto/Grande Punto/Punto Evo, Fiat 500, Fiat Panda, Fiat Idea, Fiat Palio, Ford Ka (2nd generation), Fiat Linea, Lancia Musa, Lancia Y.

Fiat engines of the FIRE series (Fully Integrated Robotised Engine - completely assembled by robots engine) for over 30 years. The range of powertrains covers wide range engines with a working volume from 769 cm3 to 1368 cm3, and 8-valve versions were later supplemented with 16-valve ones. Two 8-valve units without hydraulic pushers are worthy of attention.

In general, all versions of engines with an 8-valve head, regardless of the displacement, turned out to be very durable. The simple design showed high wear resistance even in small displacement engines (eg 1.1). Outdated 8-valve versions after a timing belt break will not require a major overhaul, which is inevitable for more modern modifications, which have a higher compression ratio and comply with Euro-5 standards.

FIRE engines have always been characterized by "plasticity" of character. Incredibly, two absolutely identical motors after running in behaved completely differently. So with calm drivers, he behaved lazily, and with temperamental drivers, he behaved more briskly.

Regular maintenance involves changing the timing belt, spark plugs and a reasonable oil change interval (in Europe it is a maximum of 15,000 km). These engines are absolutely reliable - they can only occasionally be disturbed by minor oil leaks.

Ford 1.38VDuratecRocam"

Production: 2001-2008

Application: Ford Ka (1st generation), Ford Fiesta VI.

The engine is similar in design and parameters to the older 1.3 OHV. It has a cast iron block, timing chain and hydraulic tappets. The power unit is rather lazy, but absolutely reliable. It has good traction at low revs and requires minimal operating costs. The motor was assembled in Brazil and South Africa (South Africa). The abbreviation Rocam stands for Shaft with Roller Bearings.

Along with the ancient OHC "Pinto" unit (used, for example, in the Ford Sierra), this is one of the most reliable engines that has ever been under the hood of a Ford. The larger 1.6L Rocams are much rarer. They were used mainly in the "charged" Ford SportKa and Ford StreetKa.

Honda 2.2i-DTEC

Production: 2008-2015.

Application: Honda Accord 8th generation, Honda CR-V 3rd generation, Honda Civic - 9th generation.

In fact, 98% of Honda's gasoline units could be listed here, and no one would object. But much more interesting is the fact that the Japanese diesel engine turned out to be very reliable. And this despite the fact that its design uses all the most vulnerable elements of modern diesel engines, which the best of competitors cannot cope with.

Using a single-row timing chain is completely counterproductive, not to mention a thermally unstable aluminum block with thin, dry steel cylinder inserts (complicating heat dissipation) - any connoisseur will tell you BMW diesel N47.

In 2.2 i-DTEC, such a set works properly for a long time. Even the piezoelectric injectors, the turbocharger (has water-cooled bearings) and the electrically controlled EGR valve do not cause problems. The normally carbonized swirl flaps in the intake manifold have been replaced bypass valve at the entrance to the bifurcated intake duct, and the EGR was "connected" behind it.

The only known drawback is the failure of the differential pressure sensor of the DPF filter.

Mercedes M266 (1.5/1.7/2.0)

Production: 2004-2012.

Application: mercedes a-class(W/C 169), Mercedes B-Class (T 245).

Strong and reliable diesel engines from OM601 to OM606 are known from the legendary W124. But they are long out of date. However, among the newer units you can find a hardy motor. This is M266. The 4-cylinder petrol engine is an evolution of the previous M166, known from the first A-Class and Vaneo.

The engine received a specific design, as it had to be placed at a large slope in a cramped engine compartment. The engineers relied on simplicity: only one timing chain and 8-valve gas distribution mechanism.

The mechanical part is very reliable. Injector failures are very rare (which is somewhat surprising for an indirect injection gasoline engine). But in most cases, the defect manifested itself in warranty period service.

All three versions of the motor are very hardy. The presence of turbocharging for modifications of the A200 Turbo theoretically increases the likelihood of malfunctions, but in reality nothing of the kind happens. The disadvantages include slightly increased fuel consumption, but this merit is not enough good aerodynamics of the body.

Mitsubishi 1.3/1.5/1.6MIVEC (series 4A9)

Production: since 2004.

Application: Mitsubishi Colt, Mitsubishi Lancer, Mitsubishi ASX, Smart ForFour, Citroën C4 Aircross.

Almost all gasoline Mitsubishi engines very reliable, so it is not easy to choose the most-most difficult. One of the most common is the 4-cylinder unit of the 4A9 series. It was created in a Mitsubishi/Daimler-Chrysler collaboration and is one of the most reliable engines on the market today.

4A9 is made entirely of aluminum, has a 16-valve DOHC gas distribution system, variable valve timing inlet valves with electronic control MIVEC (some versions of the engine with a working volume of 1.3 liters are deprived of it). Although the engine is over 10 years old, no problems are known. Cars with such engines come to the service only for maintenance - replacement, oil, filters and candles.

4A9 is only atmospheric. Turbocharged Colt CZT/Ralliart models use a completely different Mitsubishi "Orion" engine. The Citroen C4 Aircross inherited the engine from its tech twin, the Mitsubishi ASX 1.6 MIVEC, but sold it under the simple name 1.6 i, and in some markets even the downright amazing 1.6 VTi.

PSA 1.4HDi 8V(DV4)

Production: since 2001.

Application: Citroen C1, C2 Citroen, Citroen C3, Citroen Nemo, Peugeot 107, Peugeot 1007, Peugeot 206, Peugeot 207, Peugeot Bipper, Toyota Aygo, Ford Fiesta, Ford Fusion Mazda 2.

The small 1.4 HDi can be seen as the successor to the legendary XUD7/XUD9. Even despite the fact that "on paper" the 1.4 HDi was created in collaboration with Ford (as was the larger 1.6 HDi). In fact, this is a completely French design, which turned out to be very successful.

Like Honda, the French were able to create a solid aluminum block with dry inserts. The timing belt is capable of going 240,000 km or 10 years. A simple turbocharger will last forever. injection system common rail manufactured by Siemens has proven itself from the very beginning. Mazda, Ford and some PSA models have recently mentioned the Bosch injection system.

Initiates know that there is also a 16-valve version with a return of 90 hp. for more powerful options - Citroen C3 1.4 HDi and Suzuki Liana 1.4 DDiS. With its leaky 16-valve head, variable geometry turbocharger and Delphi injection system, this engine will never match the simple 8-valve version in terms of reliability.

Subaru 3.0 / 3.6R6 (EZ30 /EZ36)

Production: since 2000.

Application: Subaru Legacy, Subaru Outback, Subaru Tribeca.

Of all the illustrious Subaru boxers, the most reliable are the naturally aspirated six-cylinder EZ series, known from the Outback, Legacy 3.0R and the Tribeca crossover. The first versions of the 3-liter Outback H6 (219 hp until 2002) still had a mechanical control drive throttle valve and aluminum intake manifold. Later modifications (245 hp), despite more sophisticated technologies (among others, the system for regulating the height of the lift and the phases of the intake valves, and in 3.6 also the exhaust ones), did not become more “vulnerable”.

The engine has so-called wet cylinder liners and a durable timing chain. The only real drawbacks are the relatively high fuel consumption (especially in the Legacy 3.0 Spec B equipped with a sports manual with a short-throw gear selector) and minor difficulties when maintenance(for example, to replace spark plugs due to poor accessibility to "horizontal" cylinders).

Suzuki 1.3/1.5/1.6DOHCM"

Production: since 2000.

Application: Suzuki Jimny, Suzuki Swift, Suzuki Ignis, Suzuki SX4, Suzuki Liana, Suzuki Grand Vitara (1.6), Fiat Sedici (1.6), Subaru Justy III.

M series engines include 1.3, 1.5, 1.6 and 1.8 small capacity motors. The latter is exclusively for the Australian market. On the European continent, the power unit is found in almost all small and medium Suzuki models that appeared at the turn of our millennium, and in the Fiat Sedici 1.6, which is a copy of the Suzuki SX4. The mechanical part of the engine is very reliable and durable. Even the VVT ​​variable valve timing system, which is used by most engine modifications, is not satisfactory. It is not only in the 1.3-liter version, designed for Ignis and Jimny until 2005, and the old 1.5 modifications for the SX4.

The timing chain drive is reliable. Among the minor flaws, small oil leaks through the stuffing box can be noted. crankshaft. More serious malfunctions are almost never encountered.

Toyota 1.51NZ-FXE Hybrid

Production: since 1997.

Application: Toyota Prius I, Toyota Prius II, Toyota Yaris III Hybrid.

As with Honda, this review almost all Toyota engines could get in, but let's focus on the hybrid, which is still perceived by most motorists with skepticism. And this despite the fact that this power unit has unprecedented reliability. Simple gasoline engine high compression, Atkinson cycle, permanent magnet synchronous motor and nothing else.

There are no gearboxes in the classical sense, and therefore there are no problems with this device. Instead, a planetary gearbox with two inputs and one output is used. gear ratio varies depending on the difference in the speeds of rotation of both engines.

The most frightening thing is the expensive battery. But so far none of the owners have changed it. European competitors can not oppose anything to the phenomenal Japanese reliability.

Volkswagen 1.9SDI /TDI

Production: 1991-2006 (in some markets until 2010).

Application: Audi 80 B4, Audi A4 (1st generation), Audi A3 (1st generation), Audi 100/A6 (C4), Audi A6 (C5), Seat Alhambra, Seat Ibiza, Seat Cordoba, Seat Inca, Seat Leon, Seat Toledo, VW Caddy, VW Polo, VW Golf, VW Vento, VW Bora, VW Passat, VW Sharan, VW Transporter, Ford Galaxy(1st generation), Š Koda Fabia and Š koda Octavia(1 generation).

Undoubtedly, this is one of the most famous, but perhaps the most controversial engine on our list. The SDI/TDI engines are based on the old 1.9 D/TD. They received direct injection, thermal loads on the head of the block were reduced and a Bosch rotary pump was installed, however, it is sensitive to fuel quality.

The reliability and durability, especially of the simple naturally aspirated 1.9 SDI versions, deserves respect. The engine is able to cover more than one million kilometers without major investments. Commonly Mentioned Sensor Issues mass flow air is not taken into account.

Paradoxically, the most reliable turbocharged option is only the 90 PS TDI with a maximum torque of 202 Nm (code designation 1Z or AHU). This turbodiesel appeared in the early nineties and was used in Audi, Golf III, Passat B4, Seat until 1996-1997.

Among the Skoda Octavia, the CMA is considered the best TDI. Its small fixed-geometry turbocharger exhibits much greater survivability than the 90-horsepower ALH's variable-geometry supercharger. The latter was prone to blade sticking, just like the 110 hp version.

The only weak point of SDI/TDI, especially in the early years of production, is the crankshaft damper pulley.

Surely a large number of motorists and just motorists, who do not even have their own vehicle, wondered about the reliability of power units. Many people are really interested in learning about the most reliable engines that have been and are still being installed on various passenger cars.

This can be a key factor when choosing a new car. Everyone wants to get at their disposal the most reliable, practical, resourceful and maintainable internal combustion engine. And here a natural dilemma arises as to which are the most reliable, who to give preference to and what you should pay attention to.

Literally 30 years ago, the key indicator for determining the best motor was its volume. How more ICE, the better it is supposedly. But this was a temporary trend, which soon lost its relevance. AT modern world In the automotive industry, volume is not at all an indicator of quality or reliability.

The main emphasis is on reducing the design dimensions and working volumes of the engine while maintaining high performance performance. This led to the fact that traditional naturally aspirated engines began to gradually lose their positions under the onslaught of turbocharged internal combustion engines. At the same time, all categories of motors remain equally relevant and in demand.

In the current rating, you can find out which car engines are currently positioned as the most reliable and durable. Some of them have been discontinued, but they are regularly found on the secondary market. Others are installed in engine compartment cars so far. Which is not surprising, given the level of their quality and resistance to rapid wear. The current rating, where the engine reliability indicator will be considered, will turn out to be extremely useful for one, and simply interesting and informative for the other.

Motor Selection Criteria

1. Relevance. It makes no sense to talk about motors that have practically not survived to this day and are installed exclusively on rare, extremely rare Russian roads, cars. In the top among the most reliable passenger cars only those internal combustion engines that are still produced, or have not lost their relevance in the secondary market, were included.
2. Availability on the Russian market. Few people will be interested in reading about the most reliable engine that cannot be studied in practice or tested by personal example. The main emphasis is on internal combustion engines, which are widespread not only in the world, but also specifically in Russia. Knowing which engine is the most reliable will make it much easier for potential buyers when choosing a new car.
3. ICE type. The current rating does not provide separate categories for determining which diesel or gasoline engine is the most reliable. The rating consists of internal combustion engines of different categories.
4. Automakers. The list will include only the most reliable engines, including gasoline, diesel and turbocharged, designed for cars and produced by companies that are relevant for Russia and the CIS countries. This makes it possible to exclude extremely rare and unclaimed internal combustion engines, despite their superiority in one way or another. The main focus is on cars that can be found in car dealerships and in the secondary market.

Having received certain initial data, you can take a closer look at the most reliable engine that a particular company can offer for certain models of its passenger vehicles. For some, the gasoline ICE project turned out to be extremely successful, in another case, diesel and even turbocharged engines deserve praise, despite certain claims to the durability of turbochargers.

Rating representatives

The current top, which included the 10 most reliable passenger engines, is represented by the following manufacturers of the most successful and high-quality engines internal combustion:

• fiat.
• Ford.
• Honda.
• Mercedes.
• Mitsubishi.
• Subaru.
• Suzuki.
• Toyota.
• Volkswagen.

But you need to talk about each motor in accordance with established order. This will provide an opportunity to learn about the current top 10 among the most reliable engines designed for passenger vehicles. We will briefly tell the history of the engines, the dates of their production, as well as a list of models for which these internal combustion engines can be found.

Opens our rating almost the most reliable Fiat engine throughout history. It is often positioned as a millionaire, because with proper operation it is really able to overcome the bar of 1 million kilometers.

To be completely objective, two Fiat engines, which are called FIRE, must be added to this list at once. And in this case we are talking about the abbreviation, which stands for Fully Integrated Robotized Engine. This means that the internal combustion engines are completely assembled by robots.

The first engine of this series appeared and has a volume of 1.2 liters. The second FIRE engine has already received a volume of 1.4 liters, and production started in 2003. It will not be difficult to meet such internal combustion engines in 2019, since they are installed on:

• Fiat Punto.
• Fiat 500.
• Fiat Idea.
• Ford Ka 2nd generation.
• Lancia Musa.
• Lancia Y.
• Fiat Linea.
• Fiat Palio.
• Fiat Panda.

The first motors of the FIRE series are already over 30 years old. Their lineup is much wider, although only 2 representatives made it into the rating. Other internal combustion engines have a volume of 0.8 to 1.4 liters. In addition to 8-valve versions, 16-valve internal combustion engines were also produced. It was the eight-valve without hydraulic pushers that turned out to be the most reliable.

All ICE versions with 8 valves are considered durable at any displacement. This is due to the simple design and excellent wear resistance. Even when the 8-valve ICE faced the problem of a broken timing belt, it did not require a major overhaul.

These motors have long confirmed their status as the most reliable and successful engines Italian automaker. If you want to maximize their service life, then you will need to regularly change the timing belt, candles and choose the optimal time interval between engine oil changes.

It has long been known that almost the most reliable engines are produced by the American automaker Ford. Various engines of this brand have repeatedly demonstrated their viability, durability and reliability.

The current rating includes a small-capacity power unit with a volume of 1.3 liters with 8 Duretec Rocam valves. ICE was produced for a relatively short time, since assembly started in 2001, and stopped already in 2008. But this motor can easily be found on Ford models Ka of the first generation, as well as on the more relevant for Russia model Fiesta 6 generation.

Structurally and in terms of performance, this engine is somewhat reminiscent of 1.3 OHV. There is a cast-iron block, a chain on the gas distribution mechanism, as well as hydraulic pushers. Despite the small power, the motor turned out to be incredibly reliable. It pulls well at low speeds, does not require large investments in operating costs.

If you do not take into account the long-outdated, but legendary Ford ICE OHC Pinto, 1.3 Duratec is rightly considered one of the best engines that have ever been installed in the engine compartment of Ford cars.

2.2 i-DTEC by Honda

Continues our rating, which contains the most reliable and most durable engines designed for passenger cars, the development of the Japanese auto concern Honda. This 2.2-liter ICE is found on the following machines:

• Honda Accord 8th generation.
• Crossover Honda CR-V 3rd generation.
• 9 generation Honda models Civic.

The motor was produced from 2008 to 2015. In the case of Honda, there are a huge number of extremely successful gasoline projects. Few people would be surprised or object to the inclusion of almost the entire engine line in the ranking of the best gasoline ICEs. Japanese brand.

Therefore, it is much more interesting when the most reliable Honda diesel engine gets into the top. In reality, diesels are not Honda's forte. But this particular project is one of the most successful projects in the history of the Japanese auto company. And against the background of recognized leaders in diesel engines, 2.2 i-DTEC has a number of advantages.

Japanese engineers managed to profitably use rather vulnerable components that are relevant for diesel engines. But if diesel competitors break down every now and then or show characteristic malfunctions, Honda's development continues its confident movement.

In theory, it was completely reckless to use a single-row timing chain and an aluminum block with thin, dry steel cylinder inserts, which made it much more difficult to remove excess heat. But in practice, Honda managed to make sure that the engine runs excellently and without complaints about potential weaknesses. There are no problems with the operation of the piezoelectric injectors, the turbocharger and even the electrically controlled EGR valve, which is surprising and unusual for many.

M266 by Mercedes

If we talk about the most reliable car engines installed on modern passenger models, it is impossible not to mention the company Mercedes. This developer has always been famous for reliable and durable internal combustion engines. Although recently the status of the leader in this component has been shaken.

But this does not apply at all to the M266 motor, which has 3 different displacements. This is an internal combustion engine for 1.5, 1.7 and 2.0 liters. They were produced from 2004 to 2012. Installed on the following vehicles:

• Mercedes A-Class W169.
• A-Class C169.
• Mercedes B-Class T245.

If we talk about which diesel engines are currently the most reliable and most durable, fans Mercedes will surely remember a number of successful projects. Particular attention is paid to OM601-OM606 engines. Yes, each of them is extremely hardy and trouble-free. But they were also installed on the legendary W124 cars. Currently, they are naturally outdated.

Considering more modern developments, then the M266, albeit gasoline, will be the clear favorite in terms of reliability. These are 4-cylinder internal combustion engines, which have actually become an improved version of the M166 installed on the first A-Class and Vaneo cars.

The motor is somewhat unusual constructive solutions. This is due to the fact that the engine needed to fit in a compact engine compartment at a certain slope. Mercedes experts have focused on the simplicity of the device. The result was one

And the classic gas distribution mechanism with 8 valves.

There are no complaints at all about the mechanical component of the motor. Reliability in fact high level. Although occasionally there may be problems with injectors. At the same time, you should not be surprised here, since we are talking about a gasoline engine that uses indirect injection.

All three versions, having different working volume, turned out to be extremely hardy. Hence the well-deserved entry into the rating of the most reliable car engines. Moreover, the A200 Turbo turbo modification is included in the list. In theory, it may seem that the turbine increases the likelihood of various kinds of defects and malfunctions. But in practice, everything turned out to be completely different.

A conditional disadvantage can be called a slightly increased consumption of gasoline. But here rather a problem not in engines, but in the design features of the body of the machines on which they were installed. Far from ideal aerodynamics provokes increased fuel consumption.

Mitsubishi MIVEC

When it comes to new internal combustion engines, Mitsubishi is an indispensable participant in this conversation. Currently, the manufacturer offers extremely reliable and modern engines that are still relevant today.

It is important to make one clarification here. Only MIVEC 4A9 series motors are considered, having a working volume of 1.3, 1.5 and 1.6 liters. They have been produced since 2004. Applies to the following vehicles:

• Mitsubishi Colt.
• Mitsubishi ASX.
• Mitsubishi Lancer X.
• SmartForFour.
• Citroen C3 Aircross.

The lists of the most reliable car engines must necessarily include the gasoline developments of the Japanese company Mitsubishi. Moreover, you can easily make a list of ten internal combustion engines of this brand only. But since we have a consolidated top 10, where it is worth allocating a place for each worthy manufacturer, in the case of Mitsubishi, we will single out the 4A9 engine.

It is not only one of the most common, but also objectively extremely hardy and durable. Specialists from 3 auto concerns worked on the 4A9 project at once. These were engineers directly from Mitsubishi itself, as well as expert groups from Daimler and Chrysler. 4A9 is still one of the most reliable internal combustion engines offered in the international arena.

This is an all-aluminum engine with a 16-valve DOHC gas distribution system and a variable valve timing system MIVEC. It is important to consider that several 1.3-liter versions of the last system are deprived.

Some motors have been skated for more than 10 years. At the same time, no significant problems and shortcomings have been identified so far. If the car owner comes to the car service, then mainly as part of a scheduled maintenance, to replace working fluids, candles and filters. It is also important to remember that all 4A9 modifications are exclusively atmospheric.

1.4 HDi V8 by PSA

If anyone does not know or has forgotten, then PSA is an association of two French automakers represented by Citrioen and Peugeot.

1.4 HDi is a small displacement, but extremely high quality and durable engine, which became the successor to the legendary French motors XUD7 and XUD9. Based on the documentation, this engine is considered a joint development of PSA and Ford. The situation is similar with the older 1.6 HDi engine. But in fact it is fair to call these projects purely French. Ford's involvement in design and development is minimal.

The French managed to build a high-strength aluminum block and use dry inserts. The factory timing belt has an impressive resource of about 240 thousand kilometers or 10 years of operation. The turbocharger is structurally extremely simple, which is why it works almost forever. It is based on the injection system, which is well known under the name Common Rail and was developed by PSA partner Siemens. Although recently, the injection system from Bosch, which is installed on some cars manufactured by PSA, Mazda and Ford, has been increasingly mentioned.

Some will say that there is also a version with 16 valves and increased to 90 horsepower. They are put on the Citroen C3 and Suzuki Liana. But there is a wide range of problems here. The main ones are leaking cylinder heads, a complex turbocharger and a far from exemplary fuel injection system from Delphi. When compared to the simplified 8-valve version, the 16-valve does not come close to showing the same reliability indicators.

EZ30 and EZ360 from Subaru

These are two engines of 3.0 and 3.6 liters produced by the Japanese company Subaru. These motors have been around since 2000 and are still in production today.

Such internal combustion engines are installed on the following models:

• Subaru Outback.
• Subaru Legacy.
• Subaru Tribeca.

Among all the boxer power units that Subaru has produced in its history, six-cylinder naturally aspirated internal combustion engines are considered the most reliable and durable. They belong to the EZ series.

The first versions of the 3.0-liter engine were produced until 2002 and were installed on the Outback. They received a mechanical drive that controls the throttle, as well as an aluminum-based intake manifold. Modifications with a return of 245 horsepower, which appeared after 2002, received more sophisticated technologies, but this did not reduce the level of reliability.

The motors are equipped with wet cylinder liners and high-strength timing chains. A relatively significant disadvantage can only be called increased fuel consumption and some difficulties in finding a good service center for maintenance.

DOHC M by Suzuki

This includes 3 engines at once, which have different volume. The younger one goes for 1.3 liters, the middle one is designed for 1.5 liters of working volume, and old motor received 1.6 liters. ICEs of this series have been produced since 2000.

DOHC M automobile engines from the Japanese manufacturer are quite actively used on various models, and not only under the Suzuki brand:

• Suzuki Jimny.
• Suzuki Swift.
• Suzuki SX4.
• Suzuki Liana.
• Suzuki Grand Vitara.
• Subaru Justy 3 generations.
• Fiat Sedici.
• Suzuki Ignis.

The M series engines are where the oldest representative received a working volume of 1.8 liters. But for Russian consumers it is not interesting because it is focused strictly on the Australian market.

The remaining engines have become widespread in Europe and Russia. They are characterized by increased reliability of the mechanical component. There are also no complaints about the VVT ​​variable valve timing system, which is available on almost all modifications. The exception is old version 1.5-liter, which was installed on the SX4, as well as a 1.3-liter engine, relevant for Jimny and Ignis until 2005.

Experts speak positively about the work chain drive Timing. Sometimes there is such a minor problem as a small amount of oil leaking through the crankshaft seals. And about some more serious problems do not have to speak.

Toyota 1NZ FXE

One of the most interesting engines in this rating, which has been produced since 1997 by Toyota. The engine has a working volume of 1.5 liters. But most main feature is the fact that it is a hybrid unit.

It is widely used on the following models:

• Toyota Yaris 3rd generation.
• Toyota Prius 1 generation.
• Second Toyota generation Prius.

It would be quite fair to include a wide list of engines manufactured by the Japanese brand in the reliability rating, since they really are of high build quality and exemplary durability. But the choice eventually fell on a hybrid engine, which is simply more interesting than all the others.

Many people are still extremely skeptical about hybrids, considering them to be short-lived, difficult to maintain and extremely problematic. This is a big misconception when it comes to hybrid powertrains from Toyota. And all thanks to an extremely simple design. It is based on a gasoline internal combustion engine, characterized by a high degree of compression. It works on the Atkinson cycle. Supplements gasoline engine electric synchronous motor with permanent magnet. That's the whole structure.

Also in the presented cars on which such a motor is installed, there is no concept classic box gear, which automatically eliminates any problems with it. But here there is a planetary gearbox with one output and a pair of inputs.

The most frightening thing about buying such a hybrid from Toyota is the need to buy an expensive battery when it fails. But in practice, almost no one has come across such a situation. Regular batteries are still holding confidently.

1.9 SDI and TDI from Volkswagen

For the first time, these motors began to be produced in 1991, and production lasted until 2006. Although in some markets the engines lasted until 2010.

The list of cars on which these engines are found is huge. Let's name the most popular of them:

• Audi 80 B4.
• First Audi generation A4.
• First generation Audi A3.
• Audi 100 and A6 C4.
• Seat Ibiza.
• Seat Leon.
• Volkswagen Caddy.
• Volkswagen Polo.
• Volkswagen Golf.
• Volkswagen Passat.
• Skoda Octavia 1st generation.
• Skoda Fabia 1 generation.
• Volkswagen Transporter.
• Ford Galaxy 1st generation, etc.

Very popular, widely known, but also quite controversial motors. But they still deserve to be included in the current rating.

In fact, these ICEs are based on older D and TD engines with a displacement of 1.9 liters. Updated versions have immediate system injection, use rotary pumps from Bosch and a number of other modifications. Their main problem is the increased sensitivity to the quality of the diesel fuel being poured. As you understand, we are talking about diesel units here.

In terms of reliability and durability, the usual atmospheric 1.9 SDI is considered a more priority solution. Although the turbocharged TDI is not far behind. Practice has shown that such power units can easily overcome the mark of 1 million kilometers, without requiring huge maintenance and repair costs. It just needs to be noted frequent problems with a sensor that is responsible for the air flow. But this is not such a significant problem to have reason to exclude the motor from the rating.

This is far from full list those engines that can rightly be described as reliable, high-quality and durable.

But the reliability and long service life of an internal combustion engine, like any other type of power unit, depends not only on a well-thought-out design and a properly designed project. Although this factor is of great importance. Also, a large share of the responsibility lies with the owner of the vehicle.

Motors

If you know about "dieselgate" and the scandal with heavy fuel engines in Germany, then you are already rubbing your hands in anticipation of very cheap cars on the Russian market. Diesel cars have shown their inability to meet environmental standards and requirements. But in Russia this indicator is not taken into account as strictly as in Europe and the USA. There, the environment has become the main means of speculation by politicians and corruption schemes, while in our country reality is assessed much more adequately. It's time to think about which diesel engines to consider for purchase. Manufacturers' catalogs contain dozens of motors with different characteristics that fully meet the requirements for reliability and confidence of movement. Today we will figure out who is the manufacturer of the most reliable diesel engine with high potential and certain advantages over rivals.

Find the best technical solution not so easy. Among all modern technologies even a few worthy units are not easy to choose. On the one hand, German diesel engines demonstrate good opportunities. On the other hand, branded french cars on heavy fuel also do not lag behind in technology, reliability and operational capabilities. The question is not only who the manufacturer is, but also when the unit was developed. There are dozens of criteria worth considering in this aspect. But most of them are purely technical, so for a non-specialist in the production or maintenance of cars, such numbers will not say anything. Let's look at a few of the most successful motors, which actually have desired characteristics for purchase. In this case, you can easily choose a decent option without a lengthy comparison.

Volkswagen 2.0 TDI Common Rail 140 HP

Talking about 2-liter German diesel engines is somehow not accepted in modern automobile society. Journalists politely walk away from the conversation, experts shake their heads disapprovingly. It was this unit that caused all the problems of a diesel nature in the USA and Europe. But in other countries they are happy to buy it today. The machine with the unit in the 140 horsepower version has the following pleasant characteristics for the owner:

• 140 horses and very noticeable torque from the most low speed they give simply amazing dynamics and excellent power, which is felt when driving a car;
• fuel consumption on the Passat, for example, in the city is kept within 7.5 liters per 100 km, and on the highway, diesel consumption drops to 5 liters per hundred, which is confirmed on average by logbooks;
• the elasticity of work is excellent, it is immediately felt that the most famous diesel engineers in the world worked on the engine, and the engine inherited its abilities from a huge series;
• reliability has been proven by millions of buyers around the world, reviews of the 2.0 TDI engine from Volkswagen are very surprising, which contributes to their active sale to this day;
• maintenance is not as expensive as for other diesel engines of many other concerns, the engine design is not so simple, but special attention it does not require operation.

This is the main data about the engine with a volume of 2 liters and a potential of 140 horses. There are versions of this unit even with 110 hp, which were installed on Caddy and other cars without significant power requirements. But in fact, it is the 140 hp device. demonstrates its readiness for modern operating conditions. The motor will delight you with its qualities and the ability to work in all modes.

Renault 2.0 DCI 177 horses - super motor

Renault's new diesel engine has been developed for the current generation Koleos. At first it was believed that diesel would not be supplied to Russia, selling it only in Europe. But it turned out that Europeans are quickly losing interest in heavy fuel and cars with engines running on such fuel, so Russia received additional equipment in the crossover line. The engine has the following interesting characteristics:

• a simple 2-liter volume and a very groovy 177 horsepower pull a large crossover well, accelerating it to 100 km / h in 9.5 seconds, which is very good in this segment;
• torque of 380 N * m is already available at 2000 rpm, traction is simply magnificent, from the very bottom the engine works perfectly and follows all the instructions of the driver;
• fuel consumption in the city according to the passport is 6.1 liters, on the highway you can invest in 5.7 liters per 100 km, which makes the crossover one of the most economical in its class of elite vehicles;
• reliability has not yet been tested well, but today we can say that the motor has passed all possible tests and has become one of the most interesting for experts and car buyers;
• the engine comes complete with an automatic, there is an all-wheel drive, which even takes a little fuel and dynamics, and this indicates an excellent tuning of the power plant.

The French did their best and created a real warrior. A Koleos car with such a unit is able to please with fuel consumption, quality and travel conditions, reliability and endurance. The car is still very demanding on fuel quality and cannot guarantee optimal driving without proper maintenance. But this common feature all modern diesels that require decent attention.

Hyundai 2.0D 185 horsepower - Korean soldier

Another diesel unit with great endurance and amazing performance is a new Korean development. Just like in the previous version, this unit was being prepared for sale on European market. Today, this motor is equipped Hyundai Tucson new generation. But soon after the release of the car, the persecution of diesel engines began, sales in the target market fell. Interestingly, the unit has the following characteristics:

• very high quality, which allows you to cope with the greatest difficulties on the road, the motor requires only regular maintenance, reliability is proven by reviews;
• in the 2.0D unit, the Koreans offered as much as 185 horsepower, and this is very good indicator paired with a torque of 400 N * m at low engine speeds;
• in the urban cycle, the consumption is 8 liters, on the highway, fuel consumption is reduced to 5.6 liters, efficiency has become another important advantage for most buyers;
• simplicity of design becomes another reliability factor, it should be noted that maintenance requirements are minimal, and the list of materials for maintenance is very extensive;
• a car with such a motor received good dynamics and very successful characteristics, the transport has greatly changed its character in comparison with the usual gasoline engine.

Supplied motor with automatic, mechanics for Russian market not provided. The 2.0D engine from Korea has already won its fan base, who are posting accolades online. It is interesting that the reputation of the Korean motor is still clean, not negative opinions of experts and other factors that could make you think about the advisability of buying. Everything is very positive and suggests the thought of purchasing such a car.

Peugeot 1.6 HDi 120 HP - better economy

On a fairly inexpensive Peugeot 408, the manufacturer installs quite suitable and interesting engines. Transport is of the highest quality and simply excellent operating capabilities. Among the engines, there is also one diesel engine, but the range of heavy fuel units may soon expand. Even this one engine pleases with performance and can become one of the main ones on the sales list. And the reasons for this are as follows:

• the engine has only 1.6 liters of volume and 114 horsepower, while the unit drives quite well with 254 N * m of torque and a chic setting from the French;
• naturally, there is a turbocharger and all the accompanying elements of a modern engine of European origin, even if the volume is small, but the power is mediocre;
• consumption in the city will be 6.2 liters per hundred, and on the highway this figure will drop to an incredible 4.3 liters, the savings are tangible, this is what can make you buy this car in the cabin;
• reliability is perhaps a little less than in the case of German engines, but in general the unit does not cause problems in operation, so its quality is very high;
• there are no maintenance problems, the design is simple and understandable for most motorists, there is no doubt that transport will be popular in Russia in the future.

Engine tuning is one of the main good points at Peugeot. By the way, Peugeot-Citroen engines have also become the object of attention of crazy environmentalists in Europe, and this promises a reduction in prices for diesel equipment these brands in Russia. In general, it is worth waiting for when cars with diesel units will cost less than petrol versions in the cabin. It is at this moment that the time will come to go shopping.

By the way, we also offer you to watch a video review Peugeot car 408 s diesel unit under the hood:

Summing up

Much has been said about the technical advantages and disadvantages of diesel power units. In fact, everything has its advantages and disadvantages. Gasoline engines do not please with consumption, and on a diesel engine you can save about 3000 liters of fuel only during the warranty period of a car trip. Although the cost of servicing a diesel engine is somewhat higher than with a service for gasoline units, this does not reduce their financial benefits. In addition, modern diesel engines do not cause problems at all in operation. Of course, if you take the experimental Smart diesel, for example, you will definitely feel the difference for the worse.

In general, the most reliable diesel engines have long ceased to be a matter of concern for buyers. In Europe, for several years they bought almost only diesel engines and were very pleased with their quality and reliability. And most of all, it was the economy that inspired me. Nevertheless, it is worth weighing the pros and cons of operating a heavy-fuel engine in Russia, where winter temperatures sometimes exceed the freezing threshold of even high-quality diesel fuel. It is up to you to decide whether it is worth experimenting with such cars. And if you are already accustomed to operating a motor with this type of fuel, it's time to upgrade your fleet. What do you think about buying a car with one of the above motors?
