Today, there are many types and modifications of engines, and recently there has been a tendency to increase power. Moreover, manufacturers are trying to do this without increasing the working volume of the engine. For this purpose, but is it worth buying similar cars or is it better to buy an old, proven "aspirated"? This is a highly controversial issue. What is the difference between a naturally aspirated engine and a turbocharged one, we will consider in our today's article.

Characteristics of the atmospheric internal combustion engine

He is Classic System Its power supply is based on a distributed injector. So, a combustible mixture is formed from 14 parts of air and one part of gasoline. ECU if necessary modern cars can adjust this value up or down. After the mixture enters the cylinder, the system ignites it and ignition occurs, and then the piston stroke. Due to this, it rotates crankshaft, flywheel and, accordingly, the wheels of the machine.

Pressure is the main difference between a naturally aspirated engine and a turbocharged one. The pressure of the air that enters the engine is small - about one atmosphere (hence the characteristic name). There is no forced injection here.

Advantages of a naturally aspirated engine

Which is better - naturally aspirated or turbocharged? Among the advantages of the first motor, experts distinguish:

Resource

What to choose - atmospheric engine or turbocharged? On average, engines without a turbine have a resource of 300, or even more than a thousand kilometers to overhaul. And if it is an atmospheric diesel engine, then it is completely capable of traveling a million kilometers. A striking example to that - diesel engines old 124's "Mercedes". Also, these engines are easier to repair, since their design is extremely simple.

Regarding the reliability of atmospheric engines, there are no questions. Such engines can feel good even when running on low-quality gasoline. They are also not so demanding on oil. Among the special advantages should be noted their maintainability. Repair will be very cheap and will not take much time.

Disadvantages of atmospheric engines

The difference between naturally aspirated and turbocharged engines is power. Such motors will always develop less power and produce limited torque. Therefore, you should think about dynamic driving only when the engine displacement is above 2.5 liters. Most cars with naturally aspirated engines accelerate slowly.

Turbocharged engine: characteristics and advantages

Many believe that these motors were developed recently. But for the first time a turbocharged unit was installed on a car back in the 50s of the last century. Its principle of operation is somewhat different from atmospheric. So, in the design there is a special pumping mechanism. This is a turbine. She uses energy exhaust gases and thus pumps air into the intake manifold.

An artificial pressure is created, which is many times higher than atmospheric pressure. This increases the power and torque of the motor without increasing its working volume. These indicators can be higher by 20-40 percent, which, of course, affects the dynamics of acceleration of the car. High torque allows you to pick up speed faster. Besides turbocharged engine makes less noise and is more environmentally friendly. In terms of fuel consumption, it practically does not differ from its atmospheric counterparts. Such engines will be an excellent choice for those who want to enjoy driving. Overtaking on such a motor can be done with complete confidence.

Disadvantages of a turbocharged engine

When making a choice between a naturally aspirated engine or a turbocharged one, it is worth considering the fact that the latter type is more picky about fuel quality. Most engines prefer high octane gasoline. And if we are talking about a turbocharged diesel engine, you need to buy fuel only at proven gas stations. When choosing between a naturally aspirated engine or a turbocharged one, you need to understand that last motor requires better quality lubricants. Oil must be expensive and original. It needs to be changed every 10 thousand kilometers. This applies to both gasoline and diesel turbocharged engines. In addition, attention should be paid to the filter. The oil filter must be of high quality. It depends on resource and wear. important details engine.

About reliability

Which engine is more reliable - atmospheric or turbocharged? Compared to the first turbocharged engine less reliable. This is due to the more complex design. You also need to understand that all parts in such a motor are subjected to high loads. Indeed, with the same volume and design, this unit produces great features. This clearly affects the overall resource. You should know that a turbocharged engine runs at elevated temperature. Therefore, you need to check the oil more often and monitor the condition of all filters. The slightest problem with them affects performance and fuel consumption.

Unfortunately, the resource of such motors will always be lower. This is especially true for gasoline engines. bright volume an example is turbocharged engines from the Volkswagen-Audi concern.

The resource of such motors, even with timely service does not exceed two hundred thousand kilometers. Diesel engines are also available. They last a little longer. But the turbine will make itself felt anyway earlier. And then the owner will have to prepare for serious investments.

Now about the repair. It is not so easy to repair the most critical node (turbine). If she submits characteristics should be diagnosed and troubleshooted. This is best left to qualified professionals. The repair itself consists in replacing the turbine cartridge. This is the most popular recovery method. You can go the other way - install an already used turbine from disassembly. Although this option is dangerous, because no one gives a guarantee of how long it will last, what is its real mileage and in what conditions it was operated. However, all operations related to the repair and diagnosis of this element have their own difficulties. This is reflected in the final cost. atmospheric engines in this case much easier. Since there is no turbine, there is nothing to repair here.

Also note that the operation of a turbocharged car has its own characteristics. For example, after aggressive driving, you should not immediately turn off the engine. It is necessary to give him the opportunity to work at idle, so that the turbine cools down.

Summing up

Which engine is better - naturally aspirated or turbocharged? As you can see, both motors have their own characteristics. But I must say that a turbocharged engine will definitely be more expensive to repair and maintain. It is demanding on fuel and consumables. Atmospheric in this case is easier. But do not forget that a turbocharged engine gives acceleration dynamics that even a modern “aspirated” with direct injection cannot get.

There is no definite answer to the question of which is better - a turbocharged or naturally aspirated engine. But practice has shown that the content of the last motor is three times cheaper. Therefore, if dynamics is not important to you, but you need a simple car for everyday use, you should consider buying a car without a turbine. If you are a fan of speed and want to enjoy the ride, you need to put up with spending and choose a turbocharged engine. Some want to beat fate and thus buy a larger, but atmospheric engine (if there is such an option in the line of power units). In this case, do not forget about fuel consumption. The larger the volume, the more gasoline required for the operation of the cylinder. Therefore, sometimes it makes sense to buy some small-capacity, but turbocharged engine than a voracious atmospheric one.

Before purchasing a car (and it does not matter the first or next, new or used), each potential buyer faces a choice: which engine (if we are talking about a gasoline power unit) to choose - atmospheric or turbocharged. In this matter, a lot depends on personal preferences (that is, driving style), operating conditions and planned costs for its maintenance. Both types of automobile motors have both their undeniable advantages, and, of course, a number of disadvantages. Therefore, it is impossible to give a definite answer which engine is better. In our article, we will try to give comparative characteristic the main technical and consumer indicators of both motors.

Briefly recall how a gasoline engine works:

• Air- fuel mixture across inlet valve enters the cylinder.
• Then it is compressed and ignited with a spark plug.
• After ignition, the energy of the so-called "microexplosion" is transferred to the piston.
• The gases resulting from the combustion of the mixture are then discharged through the exhaust valve.

The main differences between atmospheric and turbocharged engines

It is impossible to say that atmospheric (that is, standard) and turbocharged engines are fundamentally different engines. The design and principle of operation of both units are largely similar. What is their difference? In a standard engine, air is sucked into the cylinder through an intake valve at atmospheric pressure. In a turbocharged engine, it is pumped under much higher pressure, which creates a special device - a turbine. For its rotation, the energy of the exhaust gases from the exhaust manifold is used. Structurally, the turbocharger consists of two isolated impellers mounted on one shaft.

Exhaust gases coming from exhaust manifold on the so-called "hot" blades, spin the turbine shaft. The rotating "cold" impeller picks up air and forces it under pressure into the cylinder. Since the turbine housing is heated to significant temperatures by hot exhaust gases, between the compressor and intake manifold install a special radiator - intercooler. Lowering the temperature of the charge air increases its density, which allows you to get a more enriched air-fuel mixture. With the same cylinder volume, a turbocharged engine burns much more fuel mixture in one cycle, which means more energy is released. It is due to this that they significantly exceed atmospheric counterparts in terms of power.

For information! Since everything internal details turbocharged engines experience significant mechanical and thermal loads during operation; more wear-resistant and heat-resistant materials are used for their manufacture. Because of this, the cost of the entire unit as a whole increases.

Pros and cons of naturally aspirated engines

The undoubted advantages of atmospheric engines include:

• The simplicity of the design, which has been proven in practice for many decades. Repair and maintenance of such power units cost the owner much cheaper (compared to similar operations for a turbocharged engine).
• Much greater resource uninterrupted operation before overhaul. At right conditions operation and proper maintenance, the “life” of atmospheric engines is 2–4 times longer than that of turbocharged engines: 300,000–400,000 km are often not the limit of the “longevity” of such engines.
• Less oil consumption, which, depending on the driving style, usually does not exceed 200÷500 ml per 10,000 km of the vehicle run. This is due to the absence of additional devices that require lubrication, as well as the lower loads experienced by the rotating parts of the motor during operation.
• Unpretentiousness to the quality of the oil used. They work quite satisfactorily on semi-synthetic (and even mineral) engine oils. However, one should not forget that what better oil the longer the life of the engine.
• Not as frequent as for turbocharged engines, the frequency of oil changes, which must be done after a run of 15,000 ÷ 20,000 km.
• Less demanding on the quality of the fuel used. As a rule, many atmospheric engines can work quite satisfactorily on AI92 gasoline.
• More fast warm-up in winter time.

Naturally, like any technical unit, the naturally aspirated engine has its drawbacks (compared to turbocharged counterparts):

• Less (by 30÷50%) power with the same engine size.
• Great weight and dimensions.
• Lower environmental friendliness.
• Less dynamic performance.

Advantages and disadvantages of turbocharged engines

The advantages of turbocharged engines (compared to atmospheric counterparts) include:

• Higher power (usually by 30÷50%) with the same working volume.
• Maximum torque in wide range revolutions, which has a very positive effect on the dynamics of the car.
• Less weight and dimensions with the same power. A turbocharged engine is much lighter and more compact than a naturally aspirated one. This allows the most rational arrangement of the power unit and reduces the total weight of the car, which, in turn, contributes to fuel economy.
• Fast set of working revolutions due to the lower mass of rotating parts.
• High environmental friendliness, which is achieved through more complete combustion fuel in the engine cylinders.

The main disadvantages of turbocharged engines are:

• A smaller resource compared to "atmospheric", due to the large loads experienced by engine parts.
• Short turbine life. As a rule, after a run of 120,000 ÷ 150,000 km, it needs to be replaced (even if all the required operating rules are met).
• The need to use only high quality high octane fuel.
• Increased oil consumption, as the turbine bearings heat up to very high temperatures during operation.
• The need to use only special high-temperature synthetic oils.
• More frequent oil change intervals (at least every 10,000 km).
• Long warm-up in winter.

On a note! This shortcoming can be easily eliminated by installing a special preheater. However, this leads to additional material costs.

• High cost of repair and maintenance.

About fuel consumption

If you carefully read about the pros and cons of both engines (aspirated and turbocharged), then you were surprised that we did not say anything about fuel consumption. It is worth dwelling on this issue in more detail. Let's try to figure out which motor is more economical.

First, let's compare two engines with the same volume (for example, 1.4 liters). An atmospheric engine will consume an average of about 6 ÷ 7 liters per 100 kilometers, and a trumpeted one will need 8 ÷ 9 liters. However, at the same time, it develops power 1.5 times greater than atmospheric. Conclusion: with the same working volume, the “aspirated” is much more economical (after all, it not only “eats” less fuel, but also uses cheaper gasoline), but it is significantly inferior to the turbocharged one in terms of power.

Now let's compare the fuel consumption of engines with the same power (for example, about 140÷150 hp). So many "horses" under the hood usually have a 2.0-liter naturally aspirated engine or a 1.4-liter turbocharged engine. In the urban cycle, the consumption of conventional engine will be about 12÷14 liters per 100 km, for a turbocharged one - all the same 8÷9 liters. Conclusion: even taking into account the lower cost of gasoline required for normal operation naturally aspirated engine, a turbocharged engine is much more economical.

What engine is the best car to choose

Both types of motors have their advantages and disadvantages. Therefore, it is impossible to say unequivocally which one is better. If you are a fan of aggressive driving, quick start from a place, love the drive and are ready for significant maintenance costs, then the choice is clear - a car with a turbocharged engine. However, inclining to such a choice, we must remember that the motor of your vehicle(and especially the turbine) will “live” much less than the atmospheric counterpart. In addition, you must be sure that you can easily purchase fuel in your region. High Quality, as well as special synthetic oils.

If your driving style is calm, prudent and cautious, and you are also a practical and frugal person, then the excess power of a turbocharged engine is simply not tender for you. But the reliability, ease of maintenance and durability of the atmospheric motor will significantly save the cost of its daily operation.

Every motorist sooner or later faces a choice: a car with which engine, atmospheric or turbocharged, he should buy. Both those and other power plants have their advantages and disadvantages.

atmospheric engine

This is an engine that does not have a turbocharger in its design. It operates at normal atmospheric pressure. The pistons draw air through a filtration system, where, using devices such as a carburetor or injector, this air is mixed with fuel, resulting in a combustible mixture that subsequently ignites. This principle of operation, as usual, has its pros and cons.

1) The gasoline version has a simpler structure (when compared with a turbocharged one). Therefore, its repair is cheaper.

2) It does not work under such heavy loads, and therefore the resource is higher (sometimes two or more times higher)

3) Oil consumption. There are no devices that additionally require lubrication, and therefore oil consumption is not large.

4) Oil quality. Not as demanding on oil as its turbocharged counterpart, so you can pour and mineral oils, and semi-synthetics, and synthetics. However, it is worth remembering - the better the oil, the longer the engine runs. Don't skimp on this approach.

5) Fuel quality. Less demanding on fuel quality.

6) Oil change. Oil changes after 15 - 20 thousand kilometers. Always keep an eye on the oil level, this can lead to serious damage!!

7) Warming up. The aspirator warms up faster than turbocharged options.

The advantages of such an engine are clear - it is simple, unpretentious (including fuel), cheaper to maintain, oil changes less often, etc. If you don’t “chase” around the city, then the aspirated is better, cheaper and, most importantly, more durable.

1) Power. With the same volume, it loses in power to the turbocharged version.

2) Consumption. Everything is complicated here, but I want to explain it more clearly. In general, this is how an atmospheric engine will have more volume, but the same amount Horse power like turbocharged with less volume! As a result, the cost will be higher. In simple words- "aspirated" with a volume of 2.0 liters, it produces, say, 140 hp, its consumption will be in the region of 12 - 13 liters. While the turbocharged version will have the same amount (140 hp) with a volume of 1.4 liters, and a consumption of about 8 - 9 liters.

All cons. Yes, ordinary "aspirated" are not resourceful, and are not designed for heavy loads, but durable!

turbocharged engine

The first turbocharged engine was invented by her in 1905, and on cars motors of this type began to be used in the middle of the twentieth century. The principle of its operation is that the turbine installed on the engine uses traffic fumes to create forced air pressure, which enters the cylinders, where the fuel mixture is formed. Under the influence of pressure, more air is pumped into the cylinders than in an atmospheric engine, which entails an increase in engine power (up to 10% on average).

1) More powerful. As already mentioned above, with a smaller volume, more power is achieved due to air injected under pressure.

2) Less consumption fuel (relative to horsepower).

3) It has a smaller weight and dimensions than conventional ones. And this can have a beneficial effect on the consumption and compactness of the location of the power unit.

4) They can be three or even two cylinders and very compact, especially now in the age of fuel economy. Moreover, there will be enough power, at the level of 4-cylinder atmospheric options.

5) A turbocharged engine is more environmentally friendly (more efficient combustion of fuel in the cylinders).

6) The turbocharged engine has a higher torque - this affects the dynamics better than the "aspirated" one.

7) A turbocharged engine makes less noise than a naturally aspirated engine.

Of course, there are many advantages, the main ones are lower fuel consumption and big power. But there are also a lot of cons.

1) Again, the same fuel consumption. When viewed from the side of the engine size, and not from the horsepower side, then a conventional 1.4-liter aspirated will consume less than a turbocharged 1.4-liter, but will be much weaker. Turbocharged will be superior in power to atmospheric.
Due to the fact that a larger volume of air is used to prepare the mixture in the cylinders, a larger volume of fuel is supplied there. It should not be forgotten that the turbine wears out faster if the engine is turned off immediately when the car is stopped. Therefore, to extend the life of the turbine, you need to give the motor some time to work on idling to cool the turbine, and only then turn it off.

2) More sensitive to fuel quality. If you pour "cheap" 92 gasoline at dubious gas stations, the turbine will quickly die.

3) Oil quality. You can not pour mineral water and semi-synthetics! For turbocharged options, you need your own synthetic oil, and manufacturers severely limit you, that is, a step to the right, a step to the left! And this oil is not cheap, sometimes more expensive by 30 - 40%

4) The resource of the turbine is small, about 120,000 kilometers, and then replacement will be required, even with proper care! And the replacement is very expensive!

5) It is badly heated in winter. You need to spend more time on prog.

6) Oil change. You need to change the oil after 10,000 kilometers, and not after 15 - 20,000 as on conventional atmospheric engines. oil life and oil filter in such an engine, it is reduced, compared to that of an atmospheric one, by one and a half to two times due to the fact that the turbine has to operate at higher temperatures.

7) You also need to monitor the condition air filter: if it becomes clogged, it will impair the performance of the compressor.

Thus, it can be concluded that good points and there are plenty of shortcomings here and there. But you need to remember that a turbocharged engine will require more careful care from you, although it is more powerful, it is more expensive to maintain, due to frequent replacement special oil, use quality gasoline and a short resource of the turbine itself.

Atmospheric, on the contrary, loses in power, but is more economical to use - oil is cheaper, and it needs to be changed less often, there is no turbine, and spare parts can be replaced with non-native ones and not at the dealer.

Among motorists, the following point of view has become widespread: turbocharging is unreliable, the engine with it is structurally too complicated, it is characterized by increased consumption oils, such engines are cold. In a word, it is better not to mess with them.

To the reliability of turbo engines Volkswagen Group there were indeed questions. Especially to the first engines of small displacement (1.2 and 1.4 liters) of the CBZ or CAX series. There were cases when the wear of the cylinder-piston group reached critical values ​​after 100 thousand kilometers. So there are two objective reasons. The first relates more to the operating conditions. Small engines do not like it when the tachometer needle spends a lot of time in the red zone, if the engine itself has not yet warmed up to operating temperature. They warm up longer, and a large load in an unheated state is fraught with increased wear. Well, the second reason is that the smaller the size of the elements of the crank mechanism (KShM) and the gas distribution mechanism (GRM), the faster they wear out.

However, over time, the reliability of supercharged engines has been significantly improved. On the contrary, the design complexity of some modern aspirated engines has increased and is not inferior to turbocharged engines. changeable intake tracts, direct injection, valve timing adjustment, highly lightweight KShM parts - all this is also found on non-turbocharged engines. So the only serious design difference the boost itself remains.

Further, the choice is up to the consumer, as they say, demand creates supply. And the question of the reliability of turbo engines is rather relevant for secondary market(how the previous owner operated and maintained a secret shrouded in darkness), respectively, the risks of "getting on the turbine" increase.

Modern motors on cars are increasingly becoming an element of the dispute among motorists. Downsizing - new trend in the world of transport. Volumes are getting smaller, and power, to everyone's surprise, does not decrease, but even grows. And if a dozen years ago it was possible to get about 60 horsepower from 1 liter of engine capacity, today manufacturers offer 100 or more horses from that very liter without exception. How do they achieve this? With the use of a variety of turbines and superchargers, which artificially increase the power of the engine. Many experts in this field believe that a turbocharged engine is headache for the owner, who soon after the purchase will begin to show all its shortcomings. Others are convinced that the turbine is a great invention that helps save fuel and go much faster.

The choice between a turbocharged and naturally aspirated powertrain becomes quite difficult for buyers. Often in one price category presented cars with standard traditional aspirated and turbocharged powerful engines with great potential. But it is worth remembering that a cheap turbine is practically guaranteed problems with power plant. On average, the life of a cheap motor with a powerful turbine is 150-200 thousand kilometers, after which the unit will have to be replaced. Most manufacturers, in order to save money, are switching to power units that cannot be repaired and cannot be restored for successful further operation. Let's talk about everything in order and figure out which engines are worth buying and which ones are better to refuse.

Diesel engines - you will not find aspirated

In the range of diesel power units, there are practically no simple atmospherics without a turbine. This is a rarity that is completely unjustified and will only bring trouble in operation. With a huge volume, such units give out ridiculous power and are not able to satisfy the needs of the owner. But with a good turbine diesel engine reincarnates and becomes a real masterpiece of technical art. The advantages of this technology are obvious:

• power sometimes increases several times, today diesel turbocharged units are not too inferior to their gasoline counterparts in terms of power from a certain volume;
• the thrust is simply incredible, all the advantages of a conventional aspirated diesel fuel, you can freely shift gears and elastically control the unit;
• fuel consumption is reduced if you take gasoline unit with the same power for comparison, the difference can reach a reduction in consumption by almost half;
• there are no drawbacks with diesel fuel in the fuel supply system, if you fill in high-quality fuel on proven filling stations without experiments with cheaper fuel;
• life time diesel unit actually does not depend on the presence of a turbine, so you can operate your car for a long time and not worry about breakdowns.

But this does not apply to all turbodiesels. Such an engine must be assembled efficiently and reliably. IN Chinese cars this technology is practically not used, since assembly errors can cause full output failure of the unit. You need to take this into account when buying a car. If you prefer budget transport, it is better to buy petrol car and not worry about the reliability of a simple unit.

Turbine on a gasoline engine - important advantages and disadvantages

Turbocharged gasoline engines also have a fairly large number of advantages. This is a reduction in fuel consumption in comparison with an atmospheric unit, an increase in power and an increase in traction characteristics. Also, you won't need to buy a car with a larger engine, which means that maintenance will be easier and more confident. However, a small number of disadvantages of a turbo engine should also be highlighted:

• an increase in fuel consumption with an increase in speed - at a speed after 110 km / h, the engine begins to consume an incredible amount of fuel when driving;
• rather dubious reliability in comparison with simple atmospheric engines, lack of confidence in operation due to little operating experience around the world;
• the technology is not very well proven, but manufacturers contribute more every year more changes in the design of the engine, which reduces its potential reliability;
• many companies are chasing fuel consumption and environmental standards, in which the quality and reliability of power plants, their practicality completely die;
• engine life indicators suffer, even from eminent companies, turbocharged units fail quite often, the turbine itself is a consumable.

If your car already at 30,000 km MOT determines the need to replace the turbine, you should not be surprised. It is better to take such cars in the cabin with a guarantee and receive official service. Otherwise, you will have to lay out a lot of your own money to fix factory problems. various types. It's not the most pleasant factor. current trend in the field automotive engines, but the pursuit of environmental cleanliness is doing its job.

Atmospherics - important advantages and disadvantages of units

As time goes by, we see less and less classic engines among cars sold in showrooms. Simple units cease to be interesting for a buyer who is interested in new technologies and in reducing fuel consumption. However, cars with simple atmospheric engines are still being sold and are actively finding their niche in the market. This basic configurations many cars, as well as all budget transport. The advantages of the units are as follows:

• a fairly high resource, which can often be described as a millionaire, some manufacturers make power plants that can travel even more kilometers;
• the elasticity of the unit is quite high, there are certain advantages in managing all the potential, in the rather capacious operation of all systems and simple technologies;
• gives a large volume clear benefits and a certain confidence in the trip on the highway, on high revs the engine does not heat up, its component parts do not deteriorate;
• highway operation gives a significant reduction in fuel consumption, which is not typical for an engine with a turbine, you can use the unit on high speeds without loss of economy;
• aspirators are cheaper and easier to maintain, you can save on replacement Supplies and liquids, as well as on the services of the service, you do not have to go to the officials.

Many turbocharged engines can only be serviced at an official station, as other specialists simply will not be able to deal with the power plant. But atmospherics are often repaired at service stations of any type. Are there any downsides to naturally aspirated engines? Undoubtedly. These are low indicators of environmental cleanliness, and rather high flow in urban environments, and the need to create large-capacity engines to meet the needs of car buyers.

Russian operating conditions - some adjustments

For Russia, many manufacturers prepare cars separately. This is a preparation that requires really good protection against high frosts, significant road troubles and fuel surprises. And there is a rather important point that should be taken into account. Fuel on Russian gas stations does not always match high standards quality. Therefore, there are some features of the operation of equipment:

• for high-tech turbocharged unit with small volume and high power fuel quality is one of the most important parameters operation;
• too low temperatures harm the operation of the turbine, it may not be the most economical and good decision for use in the northern regions of the country;
• atmospheric aggregates able to work with low temperatures and do well with not so good quality fuel but very sensitive to maintenance;
• in shops and stations you can often buy a fake instead of original oil than cause a number of troubles in the maintenance and subsequent operation of a good unit.

For these reasons, for Russia, engines are often bought as hardy as possible and quite well tested. And manufacturers do not always send the most technologically advanced units with the most complex and effective technical solutions to our country. Therefore, for the successful use of the engine in Russia, it is worth paying special attention to its endurance and ability to overcome unpleasant and difficult situations. We offer you to watch a short video on how turbocharging works in a power unit:

Summing up

Today, a technological engine can be called a unit with a minimum volume and an excellent power indicator. Manufacturers are squeezing more and more power from the simplest power units, installing turbines and various automations on them. This is how the supernatural is made. modern engines, which year after year receive awards at world auto shows and become the most interesting solutions in the world automotive production. Progress does not stop, but in this progress we have lost important points resource and reliability of power plants.

The problem with modern turbocharged engines is that they cannot last a good ten years and travel several hundred thousand kilometers without problems. Most likely, the car will have a number of troubles after one hundred thousand kilometers. This should also include problems with peripheral equipment due to Low quality service even at official service stations in Russia. From this we can conclude that technological units and excellent high tech while for our country are a controversial advantage. But this is an individual matter, a matter of the budget of each person. And which engine do you consider the best of its kind?

A real breakthrough in automotive world was the invention of the turbine, which may be present (gasoline and diesel). To this discovery, the designers were prompted by the desire to be able to increase power without the need to increase the working volume. So a turbocharged engine appeared, the pros and cons of which will be studied in detail in this article.

What to expect from turbocharged engines

In such a power mechanism, a mixture of fuel and air is supplied to the combustion chamber under pressure, which simultaneously increases the torque and power of the power unit. And if you use low-volume engines, you can achieve economical and high environmental friendliness. The turbine is driven by the residual energy left behind by the exhaust gases. They are also responsible for creating forced pressure in the cylinders, inside which the fuel is prepared for further work.

Turbine operation scheme

What was the favor of the drivers

Pros of power turbocharged automotive units so significant and serious that many car owners, no doubt, choose cars with just such a system.

1. Increased liter capacity, which entails high performance dynamics.
2. The design of the turbine is designed in a special way. All its features are aimed at increasing the power of the power unit.
3. The versatility of the turbine, which works great on gasoline and diesel units.
4. The presence of an intercooler - a mechanism for cooling the air inside turbocharged systems.
5. The fuel in the cylinders is burned so completely and efficiently that the environmental performance is at a very high level.
6. Quiet work.

What do you have to deal with

But is it really all that rosy and beautiful? Of course not, since there are also disadvantages, they are significant and serious, it will not work to ignore them.

1. It is worth considering the disadvantages of engines with a turbine from the price issue. For example, the closest brothers - atmospheric units have more low cost. The difference can be up to 20%. The cost to the user does not end with the costly investment. You can’t do without a special service, and you will also have to pay considerable amounts for this.
2. Active work for a long time should alternate with the rest of the turbine without turning off the engine. This will take about 10 minutes. You will forget to let the turbine run on Idling, you will often have to deal with the repair of the heart of your car.
3. Not every fuel can be used in a car with a turbocharged heart. Only high-octane gasoline and very high quality - the choice is small and strictly limited. Oil is poured not only into the engine, but also into the turbine, and bad gasoline will force the repair of the power unit after more than 100 km.
4. Fuel consumption is not the most economical, which is offset by the generation of high power.
5. The disadvantages of an engine with a turbine are also related to the thermal regime, the parameters of which are close to extreme. As a result, all nodes experience increased load, which does not have the best effect on general state mechanism. Its durability suffers significantly.
6. Careful control is required, the clogging of which leads to a deterioration in performance.

Mankind will have to wait a long time for the moment when the discovery takes place. perpetual motion machine, perfect, perfect and absolutely economical. In the meantime, we have to be content with what the leading engineers can offer us. automotive companies. The advantages of turbocharged engines are so serious and significant that even numerous shortcomings cannot overshadow them. These power units are being improved and modernized, becoming more practical, economical and durable.
