Have Japanese manufacturers reliable diesel engines. And what is the most reliable diesel engine of all the reliable ones in Japan?
Let's look at the most common modern diesel engines in the Japanese automobile industry.
What are these diesel engines, how weak and strengths Japanese diesels. They now dominate mainly in Europe, but they have begun to appear quite often in Russia.
But, unfortunately, they also have problems when their mileage exceeds one hundred thousand kilometers, and even for some up to one hundred thousand.
The caution in the supply of diesel engines from Japan is due to their capricious attitude towards fuel. Their fuel system quite weak to the use of our diesel fuel.
Another problem is the availability of spare parts. There are practically no non-original spare parts from reliable manufacturers. Chinese ones appear, but their quality leaves much to be desired and does not at all correspond to Japanese quality.
Hence their very high price, much higher than for German spare parts. There are many factories in Europe that produce spare parts decent quality and at prices significantly lower than the original ones.
The most reliable diesel engine from Japan
So what is the most reliable diesel engine from Japan? Let's rank the TOP 5 best diesel engines.
5th place
In fifth place you can safely put the 2.0 liter Subaru engine. Four-cylinder, turbocharged, opposed, 16-valve. Common Rail intake system.
It must be said that this is the only boxer diesel engine in the world.
A boxer engine is when mutual pairs of pistons operate in a horizontal plane. This arrangement does not require careful balancing of the crankshafts.
The weaknesses of this engine are its dual-mass flywheel; it failed even before five thousand kilometers. Crankshaft cracking, destroyed until 2009 crankshafts and shaft supports.
This engine is very interesting in its design, with good characteristics, but the lack of spare parts for such engines negates its advantages. Therefore he Japanese series We give diesel engines a fifth place of honor.
4th place
We'll put you in fourth place Mazda engine 2.0 MZR-CD. This diesel engine began to be produced in 2002 and installed on the Mazda 6, Mazda 6, MPV. This was the first Mazda engine with Common system Rail.
Four cylinders, 16 valves. Two versions - 121 hp. and 136 hp, both developing a torque of 310 Nm at 2000 rpm.
In 2005, it underwent modernization, with an improved injection system and a new injection pump. The compression ratio and adaptation of the engine with a catalyst for the emission of harmful gases have been reduced. Power became 143 hp.
Two years later, a version with a 140 hp engine was released; in 2011, this engine disappeared from the line of installed engines for unknown reasons.
This engine calmly nursed 200,000 kilometers, after which it was necessary to change the turbine and dual-mass flywheel.
When purchasing, you should carefully study its history, or better yet, remove the pan and look at the oil sump.
3rd place
Also a Mazda engine, Mazda 2.2 MZF-CD. The same engine, but with a larger volume. The engineers tried to eliminate all the shortcomings of the old two-liter engine.
In addition to the increased volume, the injection system was modernized and a different turbine was installed. They installed piezo injectors on this engine, changed the compression ratio and radically changed particulate filter because of which there were all the problems of the previous model of the two-liter engine.
But the global struggle for the environment, both in Europe and in Japan, adds trouble to all engines, and this is where a system is installed, with the addition of urea to the diesel fuel mixture.
All this reduces emissions to Euro5, but as always, in Russia this adds problems to all modern diesel engines without exception. This is simply solved here: the particulate filter is thrown out and the valve for afterburning the unburnt exhaust is turned off.
Otherwise the engine is reliable and unpretentious
2nd place
Engine Toyota 2.0/2.2 D-4D.
The first two-liter Toyota 2.0 D-4D CD appeared in 2006. Four-cylinder, eight-valve, cast-iron block, timing belt drive, 116 hp. The engines came with the index “CD”.
Complaints about this engine were very rare, they all boiled down only to the injectors and the recirculation system exhaust gases. In 2008, it was discontinued and replaced by a new one with a volume of 2.2 liters.
Toyota 2.0/2.2 D-4D AD
They have already begun to make it a chain one, there are already 16 valves for four cylinders. The block began to be made of aluminum with cast iron sleeves. The index of this engine became "AD".
The engines are available in both 2.0 liters and 2.2.
The most good feedback about such an engine, and good return, and low fuel consumption. But there were also complaints, the main one being the oxidation of the aluminum head at the point of contact with cylinder head gasket, approximately in the period of 150-200 thousand km. mileage
Replacing the head gasket does not help, only cylinder head grinding and the block, and this procedure is only possible with the removal of the engine. And such a repair is only possible once; the engine will not withstand the second grinding of the head and block, the depth will be critical with the possibility of the valves meeting the head. Therefore, if the engine has traveled 300-400 thousand kilometers, with one grinding, it should only be replaced. Although this is a very decent resource.
Toyota solved this problem in 2009; with such malfunctions, they even replaced the engines with new ones under warranty at their own expense. But the problem, very rarely, does occur. Mainly for those who are not weak in igniting the most powerful version of this 2.2-liter engine model.
Such engines are still produced and installed on various models cars: Raf4, Avensis, Corolla, Lexus IS and others.
1 place
Diesel Honda motor 2.2CDTi. The most reliable small-displacement diesel engine. Very productive and very economical diesel engine.
Four-cylinder, 16-valve, variable displacement turbocharged, common rail injection system, lined aluminum block.
The injectors are used by Bosch, and not the capricious and expensive Japanese Denso ones.
The predecessor to this engine was built back in 2003, badged 2.2 i-CTDi. It turned out to be very successful. Hassle-free, dynamic and economical in fuel consumption.
The current Honda 2.2 CDTi engine in question appeared in 2008.
Of course, there were no typical malfunctions, but they were all extremely rare. Cracks exhaust manifold, but they appeared in the first issues, the Japanese reacted and this did not happen in subsequent issues.
Sometimes there were malfunctions of the timing chain tensioner. Also, sometimes the turbine shaft play appeared prematurely.
All these malfunctions arose from excessive constant loads and poor maintenance.
Honda installed this engine on Honda models Civic, Accord, CR-V and others.
Of course, this engine has the lowest number of failures and breakdowns compared to all other engines from Japanese automakers.
We give it five points out of five, assign it the first place of honor and wish you to have a similar one in your car.
4 cylinders, 8 valves, direct injection – the robust engine also offers some innovative design changes. The disadvantages include perhaps not economical fuel consumption.
Owners include floating speed when the engine is idling as a typical malfunction for the model. This nuisance can be eliminated by cleaning and adjusting the operation of the throttle valve.
Overall, 1.6 MPI “runs” 500 thousand km without major interventions and does not suffer from birth defects.
1.4
This engine appeared back in 1991 with the VW Golf III. Back then it was a cast iron block with one injection point and a modest 60 horsepower. But the longevity and reliability of this model led to its improvement. Over time, the manufacturer has already offered a 16-valve version instead of the 8-valve, a multipoint injection system and even an FSI version.
Compared to the first 1.4, versions with 16 valves 1.4 MPI developed 75-101 hp. But the version with a chain instead of a timing belt, 1.4 FSI with 86 hp, is considered unsuccessful.
The 1.4 engine of this generation was installed in the Audi A2; Seat Arosa, Ibiza, Leon, Cordoba, Toledo; Skoda Fabia, Octavia, Roomster; Volkswagen Golf 3, 4, 5, Polo 2, 3, 4, Fox, Lupo. But in modern models You won't find such an engine in a golf class anymore.
In general, according to reviews from owners, the 1.4 engine is distinguished by its simplicity of design and unpretentious operation. TO typical problems motor include freezing of the outlet channel crankcase gases at low temperatures, wear of the steering hydraulic compensators and failure of the Hall sensor. The owner is in trouble only in case of CPG wear– this calls for an engine overhaul. The rest can be successfully dealt with, especially since repairing this engine is inexpensive - that’s why its owners love it so much.
1.4TSI
Under the common name there are 2 generations hidden EA111 And EA211 and their modifications. Since 2005, the 1.4 TSI has been installed on the VW Golf GT. Sequential supercharging gave the engine 170 horsepower. Soon a 140-horsepower engine modification was released, and a little later mechanical compressor removed, leaving only the pipe and a “modest” 122 hp.
In 2012, the EA111 appears and is replaced by the EA211 series with a different design. The proven EA111 can thus be found in cars until 2012: Audi A1, A3; Seat Ibiza, Altea, Leon; Skoda Fabia, Octavia, Superb, Yetty; Volkswagen Golf 5, 6, Jetta 3, 4, Polo, Passat B6 and SS, Sharan, Turan, Tiguan.
The 1.4 TSI's good reputation is ensured by its torque, efficiency and excellent dynamics.
As for typical complaints from owners, we can highlight timing chain stretching and piston failure. The latter differs in the first versions of engines (160 and 170 hp), so to purchase 1.4 TSI is better consider deformed versions.
1.2TSI
Version 1.2 with system direct injection saw the world in 2009. Volkswagen Golf 4, Jetta 4, Polo, Caddy, Turan got this engine; Skoda Octavia, Fabia, Yetty, Roomster; Seat Altea, Ibiza, Leon, Audi A1 and A3.
The goal of the designers was to offer a worthy alternative to the 1.6 MPI, smaller in volume and with reduced fuel consumption. 8 cylinder head valves, the presence of a turbine with an output of 105 “horses” are the main characteristics of the model. Previously, the lineup included an 85-horsepower 1.2 TSI.
In 2012, the timing chain was replaced with a belt.
In general, this engine fulfilled all the assigned tasks: efficiency with optimal performance - torque of 160 and 175 Nm in the range of 1500-4000 rpm.
As for the operational problems identified by the owners, in the first series this timing chain drive. In some cases, uneven operation of the engine at idle is noted, which can be solved by flashing the computer, and failure of the turbine, or more precisely, its pressure regulation system.
On average without overhaul 1.2 TSI lives 250 thousand km.
1.2
Found in the smallest cars of the VAG family: Seat Ibiza, Cordoba; Skoda Fabia, Rapid, Roomster; Volkswagen Polo 3, 4, Fox.
The engineers' decision to give life to a three-cylinder engine is associated with reducing production costs. The timing chain, which all in-line 1.2 6V and 1.2 12V received, was supposed to outperform the belt in terms of operation. But in reality this decision turned into a problem: repairs chain drive it was more expensive, and its resource was identical to that of the belt. Over time, the issue with a defective chain tensioner, due to which it jumped several links, was resolved.
Another point that causes dissatisfaction among owners is that the positioning of the ultra-high torque of the 1.2 engine does not correspond to reality. The six-valve version develops only 55 hp, while the 12-valve version is more fun: 64 and 70 “horses”. Torque reaches only 108 and 112 Nm/3000 rpm. Hence the restriction of the operation of cars with such internal combustion engines within city limits.
As for fuel consumption, it is 1.2 comparable to gasoline consumption 1.4. Only the latter has one more cylinder, which eliminates a number of operational issues.
Typical problem with petrol 1.2 - failure of the ignition coils. This is easy to determine by strong vibration, misfires and unstable engine operation.
Despite the design flaws, VW did not abandon the idea of a three-cylinder engine and in 2012 even boosted it for the Skoda Rapid, giving it 75 hp. and released modification 1.2 with a direct injection system for the Polo.
Don't miss other secrets of VAG cars:

- Hidden functions of your Audi - check.
When buying a car, every driver is interested in which one is the best reliable engine. Safety and durability of operation depend on this factor. vehicle. It should be noted that each motor has its own characteristics regarding reliability and resistance to various influences. Let's look at which engines can claim to be truly the best.
The best among diesels
First, let's determine which is the most reliable engine among diesel varieties. Let's just say that recently cars with such units have become increasingly popular. They are distinguished by their sporty character, speed, and stability of operation. If you drive a lot and often, diesel engines are simply irreplaceable for these purposes. And if the motor is of an old generation, it has a good margin of safety despite its simplicity of design.
Mercedes-Benz OM602
The most reliable for Mercedes-Benz is from the OM602 family. Such engines are presented in 5-cylinder versions. They have two valves per cylinder, a mechanical injection pump. Drivers note that this engine is the leader in the following characteristics: car mileage and resistance to environmental influences. When not the most high power(90-130 hp) units have always been considered the most reliable and economical. These motors were installed on Mercedes cars in the back of W124, W201 (MB190), G-class SUVs, T1 and Sprinter vans. If you follow up promptly fuel equipment And attachments, these diesel engines are capable of “winding up” a huge number of kilometers.
BMW M57
Probably the most reliable engines passenger cars modernity is created in Bavaria. In addition to durability, they are characterized by a sporty spirit, which fundamentally changes the image of a diesel engine. BMW engineers were able to prove to the whole world that such a unit can be fast and can be installed on any type of car. Cars have a variety of power units, and diesel engines became popular not so long ago.
Which is the most reliable among diesel engines? Experts focus on the turbocharged 4-cylinder engine BMW N47D Twin Turbo, which has a volume of 2.0 liters. It was named the winner in the "Best New Development" category. Note that this motor is installed on a huge number of models. And in general, buyers prefer diesel engines, which can freeze in winter.
BMW
The most reliable in 2016 is the BMW B58, which is installed on 340i F30 models. This is a 6-cylinder power unit, which is gradually being equipped with new models of BMW cars. Note that BMW is systematically introducing both gasoline and diesel engines of the modular family into its vehicles. Their feature is unified components and a single half-liter working volume of one cylinder. At the same time, BMW hatchbacks since 2015 have been equipped with 118i engines with a 1.5 liter turbocharger with a power of 136 hp. With. And the coupes and convertibles of the second series have 2.0 liter diesel engines.
The most reliable passenger engines BMW cars, according to experts, these are not gasoline, but TwinPower Turbo diesel units with three or four cylinders. The B47 and B37 engines are complemented by an injection system and turbochargers that can change geometry. In the same 2015, BMW models were supplemented with a new generation of productive four with a capacity of 23 hp. With. Thus, BMW engines are reliable and high-power, although simple in design.
Note that the average resource BMW engines estimated at 150,000 km, since their parts are not always of outstanding quality. In addition, not all models in the line have factory repair sizes. Therefore, problems may arise with replacing power units.
Audi
Which Audi engines are the most reliable? There is no clear answer here. But both users and experts highlight 1.4 liter gasoline engines with a power of 150 hp. pp., 190 l. With. and 252 l. With. Moreover, the latter is supplemented all-wheel drive Quattro. Among diesel units Four-cylinder TDI engines with a power of 150 hp are in demand. With. and 190 l. With. In addition to them, a 6-speed gearbox is installed manual transmission transmission
Another engine that can be distinguished as the most reliable Audi engine is the A4 Avant g-tron 2.0 TFSI (170 hp). Its special feature is the ability to operate on compressed natural gas. As for the Audi A6 model, users here highlight a three-liter naturally aspirated engine. Its reliability is explained old technology production and cast iron sleeves. True, such a motor has not been produced since 2008.
Volkswagen
It is noteworthy, but Volkswagen brand Diesel engines are considered the most reliable units. Among the entire range of engines, the most reliable Volkswagen engine is the 5-cylinder AXD with a displacement of 1.8 liters. According to both drivers and experts, this motor good for excellent power capabilities with fairly modest fuel consumption. In most cases, Volkswagen Tiguan is equipped with this unit.
It is not so easy to determine the most reliable engine among gasoline configurations. In this list, it is necessary to note the stable 2-liter AWM engine, showing a power of 140 hp. With. It is equipped with such models as Jetta and Tiguan. Among the advantages of the engine, users note excellent behavior in any driving style and on any road surface.
For a long time it was considered the most reliable. Its advantages included excellent driving dynamics, power, and fast acceleration. The unit is liked by those who often travel outdoors, where the roads are not of high quality and smoothness. The most reliable engines among six-cylinder models are ABU with a volume of 1.8 liters. With a simple design, the unit is good for drivers who are just starting to drive a car. In addition, it is balanced. When the motor operates, there is no vibration of the main mechanisms and components. This engine can last even with a mileage of more than a million kilometers.
Japanese production
The most reliable engines have always been produced Japanese brands. We offer an overview of the most popular and best in terms of quality and reliability of motors. Probably the most stable in behavior can be considered Toyota unit 3S-FE. Being reliable, it is also unpretentious. It has a volume of 2.0 l, 4 cylinders and 6 valves. This engine was installed on models such as Camry, Carina, Corona, Avensis, Altezza. According to mechanics, the motors of this series are distinguished by their amazing ability to withstand any load. In addition, it is easy to repair due to its well-thought-out design. The motor performed well in operation Toyota series 1‑AZ, whose resource is about 200,000 km.
The most reliable car engines can also be distinguished among the Mitsubishi line. The Mitsubishi 4G63 is a power unit that was constantly changing and improving, due to which it began to be equipped with a timing adjustment system and complex supercharging systems. It is noteworthy that the engine is installed not only on Mitsubishi, but also on cars of the Huyndai, Kia, and Brilliance brands. A million kilometers can be achieved by naturally aspirated engines, although turbocharged variations also have large resource work. There are no serious “illnesses” and Mitsubishi engine series 4B11, which has a resource of 200,000 km. Due to the high quality of the elements, simplicity of design, absence complex parts achieved high level reliability of the unit.
Honda D-series is a representative of the Japanese family of engines, the series of which includes more than 10 models of engines with a volume of 1.2-1.7 liters. According to experts, these are perhaps the most indestructible models, capable of showing combat character with a small working resource. Among the new products we can highlight the motor Honda series R20. He's different high quality parts, a simple valve adjustment diagram. The most reliable representative Japanese engines can rightfully be considered a Subaru EJ20 series. It is still installed on some car models, although only those used in Japan. The resource of this power unit is 250,000 km, the quality of the parts is high. True, original spare parts for the engine are not cheap.
Opel 20ne
Among the reliable ones we can mention a model from the Opel 20ne engine family. Its peculiarity is that it served much longer than cars, for which it was used. Simple design consists of 8 valves, belt drive, simple system distributed injection. This, according to experts, is what affects the longevity of the motor. C20XE is another motor that belongs to to the Opel family. It was installed on racing cars and earned good reviews for its quality, stability and simple design. True, today this power unit is rarely used to equip vehicles.
Class struggle
All modern engines can be divided into classes in accordance with the classes of vehicles on which they are installed. And this affects their technical and operational properties. So, in the small class of cars, which, by the way, is the most common in our country, they are distinguished by practicality and the absence of any serious innovations. For cars in this segment, the K7M engine from Renault is most often installed, which has the most high performance reliability. Its recipe, by the way, is very simple: the engine has a volume of 1.6 liters, 8 valves, but does not have any complex parts or mechanisms. The second and third places in the small class can be taken by the VAZ-21116 and Renault K4M power units.
In the middle segment, the K4M from Renault can rightfully be considered the leader. True, the cars themselves are distinguished by their large dimensions and power, and are equipped with automatic transmission, which increases the requirements for power and engine power. Among the cheap but practical engines in the middle class is the Z18XER, which is installed on the Astra J, Chevrolet Cruse, and Opel Zafira.
In terms of reliability, we’ll put the Hyundai/Kia/Mitsubushi G4KD/4B11 series of engines, which are always leaders in quality and performance characteristics, in second place in the middle class. Their working volume is 2.0 l, there is a timing adjustment system, simple system power supply, high build quality. Such motors can be installed on any car. high power and technology: Hyundai i30, Kia Cerato, Mitsubishi ASX, Hyundai Sonata.
Junior business class
In the junior business class, two-liter engines can be distinguished. For example, 2AR-FE with a power of 165-180 hp. with., which is equipped with Toyota Camry. This is a reliable and practical power unit. Being simple, it is distinguished by high quality workmanship. In second place in the business class are the G4KE/4B12 Hyundai/Kia/Mitsubishi engines. Cars in this segment differ in size and power. Accordingly, the engine must meet the requirements of operational reliability and manufacturability.
Senior business class
The senior business class features prestigious sedans, the maintenance of which is expensive. And the motors themselves differ in complexity and power. Leading the way in this Lexus class: 2GR-FE and 2GR-FSE engines are installed on models of this brand and premium SUVs. The operation of the motor, according to users and experts, is not characterized by any problems.
In second place in this class is the Volvo B6304T2 - a turbo engine that is cheap and easy to operate. In third place is the Infiniti Q70 VQVQ37VHR. It attracts attention with its power, glorious performance, and historical reliability. Regarding cars executive class, here you will have to do without a rating, since their operation and maintenance cost a pretty penny. Accordingly, the equipment of such machines is excellent, but requires serious investment.
conclusions
Thus, a car of almost any brand or class can be equipped with reliable and therefore trouble-free engines. When choosing a car, be sure to find out everything you can about its engine. After all, the longevity of the entire vehicle depends on its quality and reliability. True, many engines are no longer used to equip modern cars.
If diesel engines are more durable than gasoline engines, then which diesel engine is the most reliable? This is interesting, first of all, to those who travel a lot, for example, people whose activities involve frequent travel. After all, it is known that diesel engines are famous for their reliability and longer service life compared to gasoline engines. Also, such information will be useful to all other car enthusiasts for general development.
Which diesel engine is the most reliable for its class of car, why has the popularity of diesel engines been growing lately, and which power unit should you give preference to when buying a car? The answers to these questions will be revealed in this material.
Why do people love diesels so much?
We will talk about diesel engines in passenger cars, because, as you know, special equipment is always equipped with diesel engines, so comparison will not be possible.
There are always some legends about the huge resource of diesel engines, that they can last up to 1 million kilometers without major repairs. There are no such stories about gasoline engines.
In addition to large resource, the glory of diesel engines also rests on their reliability. They say that a diesel engine always works stably, starts in any weather and can withstand the most severe operating conditions. While gasoline ones suffer from some vagaries. So it turns out that diesel has two main advantages over gasoline.
The reliability and endurance of diesel engines is determined by their design and operating mode. The design of a diesel engine is somewhat simpler and includes fewer elements that operate after starting than its gasoline counterpart. And during operation, the diesel engine always operates at lower speeds, which results in long wear of parts.
Another huge plus for diesel engines is fuel consumption. If you take two modern motor, diesel and gasoline with identical power in Horse power oh, then diesel fuel consumption will be less, by 30-40%.
It is these main factors that force people to choose diesel power units. By the way, in recent years The demand for cars with diesel engines is noticeably increasing, even from premium brands. This is explained by the fact that there is no longer a stereotype that diesel engines are created for pensioners, that is, for calm ride, with a complete lack of sporting character.
Modern diesel engines are now on par with gasoline engines in terms of dynamics; a striking example of this is BMW, which has created the fastest diesel engine, which has a power of 435 horsepower and accelerates to 100 km/h in 4.5 seconds. This performance indicator would be the envy of many gasoline engines with a completely sporty character.
The most reliable diesel engines in Russia
Of all the diesel cars that are still in use in the Russian Federation, there are several that have gained the reputation of being “indestructible,” even in harsh conditions.
- The most reliable, unpretentious and hardy from Mercedes are motors of the OM602 series. They are in-line 5-cylinder and 10-valve, with a power from 90 to 130 hp.
Thanks to their popularity, they lasted a record long time on the assembly line, from 1985 to 2002. They have a very well thought out design with an emphasis on reliability and durability. Mechanical fuel injection pumps from Bosch also performed very well, which were installed on engines with which there were never any problems.
You can find such engines at passenger models– W124, W201, on trucks – T1 and Sprinter, on SUVs – Gelentwagen and even on the 210th model (W210). Such models can be seen every day on the streets of your city, which shows their durability, because most cars have mileages well over 500 thousand km, and some have more than 1 million km.
- Well-known diesel power units from BMW are not inferior in quality and reliability to Mercedes. BMW became famous for its in-line 6-cylinder diesel engines, which, unlike the OM602 series from Mercedes, had more power, and, accordingly, improved dynamic characteristics.
Diesels with which the models were equipped BMW of different series had power from 163 to 286 hp, which made them not “boring” at all. Most popular Bavarian motor considered to be the M57, which was released in 1998 and was produced until 2008. It was the 57th series that equipped most of the well-known in Russia diesel BMW, from “one” to “seven”. Its predecessor was the M51, cars with which can still be found in our time, the mileage of which has long passed the 500 thousand km mark.
- Not only German engines have won the reputation of being “unkillable”, there are also options from the Japanese. The best diesel Japanese engine is marked 1HZ. This straight six, volume 4.2 liters. The design is very similar to Mercedes, also 2 valves per cylinder and a mechanical injection pump. This engine was produced from 1990 to 1998 and has a power of 129 hp. It can also be found on our roads. 1HZ representative is Toyota Land Cruiser 80 and 100. The mileage of some copies reached a million kilometers, which speaks of reliability.
Which engine should I buy a car with?
The debate between diesel and gasoline never subsides; there are avid diesel drivers, and there are devoted fans of gasoline engines. To understand which engine is preferable, you need to understand what the automobile market offers and for what purpose the car is purchased.
As mentioned above, diesel engines can be as dynamic as sports gasoline engines. But this only applies to top models famous brands. Diesel cars, which are sold in car dealerships and are available to the public, cannot boast of high dynamic characteristics. Gasoline engines will be faster. Therefore, for people who love active and driving fast Gasoline units are better suited.
Diesel is ideal for people who need to drive a lot on country roads, this is where its main advantage manifests itself in the form low consumption fuel. Modern diesel engines can show highway consumption within 4 liters per hundred.
Also, diesel is preferable in case of calm and measured driving, because its maximum torque occurs much earlier, almost from idle and has a larger range, while with gasoline it starts from 2.5-3 thousand revolutions. To answer the question, which diesel engine is the most reliable of those offered on modern automotive market time needs to pass. After all, the design of motors has changed significantly, and perhaps they have become even more reliable.
The reliable engine is the Fiat turbocharged power unit.
Many car enthusiasts note the fact that modern engines for cars the service life has sharply decreased. If earlier multi-liter engines were called “million-dollar engines” for their enormous resources, then their modern representatives now run on average 200-300 thousand kilometers. New gasoline turbo engines, which due to the turbine were able to reduce the displacement at the same power level, also do not shine with such engine life indicators. However, we were able to find several models of gasoline engines that seemed to us very reliable in our time. modern times, when automakers, for the sake of sales, reduce the life cycle of new cars.
As you know, the “Best Motor of the Year” awards are awarded annually in the USA and Europe. The jury of these competitions are journalists from various automotive publications. Maybe motorists think that the engine internal combustion, which received the title “Best Motor of the Year” is reliable and has long service life. In reality, everything looks completely different. Journalists choose best engines according to the criteria of efficiency and environmental friendliness, power density. None of them choose best motor years according to the criterion of reliability and service life. But for car owners from all over the world, it is the last criterion that we indicated that is extremely important.
We decided from the total volume of gasoline engines produced by automobile manufacturers around the world to select the best examples that demonstrate not only a solid resource, but also low cost operation.
The best small-displacement naturally aspirated engines
We classified power units with a displacement of up to 1.6 liters as small-displacement gasoline engines. In this class of gasoline engines, manufacturers offer reliable engine models with a service life of up to 300 thousand kilometers. Among the reliable naturally aspirated engines are engine models from manufacturers such as Renault, Opel, Ford and Fiat. Such models can be considered reliable, since they were developed 20 years ago, and are still considered economical after a small modern modernization. It is not surprising, but reliable naturally aspirated engines with a displacement of 1.6 liters are supplied by global automakers to car models sold in Russia, Eastern Europe and Africa. That is, in other words, they seem to be writing off car models with such engines for developing markets. Of course, such engines do not have high efficiency and environmental friendliness, like modern gasoline turbo engines, but they are easy to repair and inexpensive. Thanks to this, automakers can reduce the cost of new cars in emerging markets.
Reliable small-displacement engines include a series of 1.6 and 1.4 liter engines. Such motors can now be found on models Ford Focus and Ford Ecosport.
EcoTec motors German manufacturer Opel are also reliable. The German automobile manufacturer Opel has a reliable small engine, the 1.6-liter A16XER engine with 116 horsepower. This atmospheric unit still installed on Opel Astra J, which continue to be sold on par with the new generation. By the way, new Opel generation Astra K completely lost its naturally aspirated engines.
Also reliable are the A14XE, A14XEP and A14XER engines with a displacement of 1.4 liters and a power of 75 to 100 horsepower. Such engines are installed on this moment on Opel model Corsa Opel Meriva and Opel Astra J. This model atmospheric engines are already equipped with a timing chain. However, its resource is limited to 150 thousand kilometers.
The French automobile concern Renault offers atmospheric small engine with a displacement of 1.2 liters and a power of 75 horsepower. It belongs to the D4F series. Unfortunately, in Russia Renault models They are not sold with this engine. However, it is considered very reliable in the French line.
The best naturally aspirated small engines are the naturally aspirated engines of the Italian concern Fiat from the Fire series. So 1.2- and 1.-liter naturally aspirated gasoline engines are installed on Fiat models Punto, Fiat Panda And Fiat Doblo. This series of engines is distinguished by a timing belt drive, one phase shifter on a 16-valve engine, cast iron block cylinders, simple injection system.
In German automobile concern Volkswagen also retained naturally aspirated petrol engines. So Czech automobile manufacturer Skoda, which is part of the VAG group, offers car models with three-cylinder naturally aspirated MPI motors. These engines belong to the EA211 series, which also includes the 1.6 MPI engine, supplied to models assembled in Russia Skoda cars. This series engines have a simple design: direct timing drive, phase shifters, an advanced electric thermostat and a cylinder head with an integrated drain manifold. True, the power of such engines ranges from 60 to 75 horsepower, but compact models Skoda this power is quite enough.
The best turbocharged gasoline engines
We can safely say that one of the most reliable series of turbocharged engines on the European market is the Opel A14NET/A14NEL series of engines. This series of engines was built on the already well-known naturally aspirated A14XER engine. Opel engineers managed to install a simple but reliable turbocharger on a naturally aspirated engine, which made it possible to increase the specific power of the new engines. The engines of this series develop power from 118 to 140 horsepower. They can be found under the hood of the Opel Astra H, Opel Meriva and Opel Insignia. The service life of such gasoline turbo engines is 200-250 thousand kilometers.
Also successful and reliable turbo engines running on gasoline are the Fire series engines from the Italian concern Fiat. These power units are also built on the basis of naturally aspirated engines and develop power from 125 to 170 horsepower. This petrol turbo engine is installed on Alfa models Romeo Giulietta, Jeep Renegade and Fiat 500.
U Renault reliable gasoline engines are naturally aspirated engines of the D4F series. Surprisingly, the engine of a German automobile Volkswagen Group is also considered very reliable, despite its great criticism from domestic car owners. Since last year, Volkswagen engineers have eliminated all the weak points of this gasoline turbo engine. The resource was raised to 200-250 thousand kilometers. However, it is still weak point The turbine and direct injection system are considered.
