Naturally aspirated or turbocharged engine - which is better? Turbocharged car engine Which engine is better atmospheric or turbocharged.

Let's start with the fact that the situation modern market new cars has changed markedly over the past 15-20 years. Changes in the automotive industry have affected both performance, equipment level and solutions in terms of active and passive safety, and power unit devices. Familiar on gasoline with one or another working volume, which used to be an indicator of the class and prestige of a car, are now being actively replaced.

In the case of turbo engines, the engine displacement ceased to protrude basic characteristic, which determines the power, torque, acceleration dynamics, etc. In this article, we intend to compare turbine engines and naturally aspirated versions, and also answer the question of what is fundamental difference atmospheric from turbocharged analogues. In parallel, the main advantages and disadvantages of turbocharged engines will be analyzed. Also, in the end, an assessment will be given whether it is worth buying new and used gasoline and diesel cars with a turbocharged engine.

Turbocharged engines and "aspirated": the main differences

Let's start with some history and theory. The operation of any internal combustion engine is based on the principle of combustion fuel-air mixture in a closed chamber. As you know, the more air can be supplied to the cylinders, the more fuel can be burned in one cycle. The amount of released energy that pushes will directly depend on the amount of fuel burned. In atmospheric engines, air is taken in due to the formation of a vacuum in the intake manifold.

In other words, the motor literally "sucks" into itself outdoor air on the intake stroke independently, and the volume of air that fits depends on the physical volume of the combustion chamber. It turns out that the larger the displacement of the engine, the more air it can fit in the cylinders and the large quantity fuel can be burned. As a result, the power of atmospheric internal combustion engines and torque are highly dependent on the size of the engine.

A fundamental feature of supercharged engines is the forced air supply to the cylinders under a certain pressure. This decision allows the power unit to develop more power without the need to physically increase the working volume of the combustion chamber. We add that air injection systems can be both and.

In practice, it looks like this. For getting powerful motor you can go two ways:

• increase the volume of the combustion chamber and / or make an engine with a large number of cylinders;
• supply air under pressure to the cylinders, which eliminates the need to increase the combustion chamber and the number of such chambers;

Taking into account the fact that about 1 m3 of air is required for each liter of fuel for efficient combustion of the mixture in the internal combustion engine, automakers around the world for a long time followed the path of improving atmospheric engines. Atmotors represented the maximum reliable appearance power units. The compression ratio increased in stages, while the engines became more resistant to. Thanks to the advent of synthetic motor oils, friction losses were minimized, engineers learned, implementation made it possible to achieve high-precision fuel injection, etc.

As a result, engines from V6 to V12 with large displacement have long been the benchmark for performance. Also, do not forget about reliability, since the design of atmospheric engines has always been a time-tested solution. In parallel with this, the main disadvantages of powerful atmospheric units are rightly considered to be large weight and increased consumption fuel, and toxicity. It turns out that at a certain stage in the development of engine building, an increase in the working volume turned out to be simply inappropriate.

Now about turbo engines. Another type of units against the background of the popular "aspirated" has always been less common units with the prefix "turbo", as well as compressor engines. Such internal combustion engines appeared a long time ago and initially followed a different path of development, having received systems for forced air injection into the engine cylinders.

It is worth noting that the significant popularization of supercharged engines and the rapid introduction of such units to the general public for a long time was hindered by the high cost of cars with a supercharger. In other words, supercharged engines were rare. This is explained simply, since at an early stage of a car with a turbo engine, mechanical compressor or a simultaneous combination of two solutions at once were often placed on expensive sports models auto.

The reliability of the units was also an important factor. of this type, which required increased attention during the maintenance process and were inferior in terms of engine life to atmospheric internal combustion engines. By the way, today this statement is also true for turbine engines, which are structurally more complicated than compressor analogues and have gone even further from atmospheric versions.

Advantages and disadvantages of a modern turbo engine

Before we begin to analyze the pros and cons of a turbo engine, I would like to once again draw your attention to one nuance. According to marketers, the share of new turbocharged cars sold today has increased significantly.

Moreover, numerous sources emphasize that turbo engines are increasingly crowding "aspirated" engines, motorists often choose "turbo" because they consider atmospheric engines to be hopelessly outdated ICE type and so on. Let's figure out if a turbo engine is really that good.

Advantages of a turbo engine

1. Let's start with the obvious pros. Indeed, the turbo engine is lighter in weight, smaller in displacement, but at the same time produces a high maximum power. Also, turbine motors provide high torque, which is available on low revs and is stable over a wide range. In other words, turbo engines have an even shelf of torque, available from the very "bottom" and up to relatively high speeds.
2. In a naturally aspirated engine, there is no such flat shelf, since thrust directly depends on engine speed. At low speeds, the atmotor usually produces less torque, that is, it needs to be untwisted to obtain acceptable dynamics. On high revs the motor reaches its maximum power, but the torque is reduced as a result of the natural losses that occur.
3. Now a few words about the efficiency of turbo engines. Such motors really consume less fuel compared to atmospheric aggregates under certain conditions. The fact is that the process of filling the cylinders with air and fuel is fully controlled by electronics.

   Features of car operation: how to properly turn off the engine and whether it is possible to turn off when the fan is running. Why can't you turn off the turbo engine right away.

4. List of the most reliable gasoline and diesel engines: 4-cylinder power units, in-line 6 cylinder internal combustion engines and V-shaped power plants. Rating.

Motorists are faced with the question of which car to prefer, a naturally aspirated or turbocharged engine should be installed on it, which would be better for new car.

Atmospheric power units

Automobile engines that are not structurally equipped with a turbocharger are classified as atmospheric. Unlike a turbocharged one, such an engine operates at a pressure equal to atmospheric.

Air masses are drawn into the filtration system of the power unit using pistons. Entering the injector or carburetor, the air is evenly mixed with droplets of gasoline or diesel fuel. The resulting air-fuel mixture is ready for ignition.

The main advantages and disadvantages of atmospheric engines

Aspirators have the following undeniable advantages:

1. The design of a gasoline naturally aspirated engine is characterized by a simple structure, which greatly facilitates repair work, reduces time costs and material costs for its restoration.
2. A high resource (more than twice) is provided due to the operation of the car at low loads.
3. Consumption reduction engine oil, since there are no additional devices that require thorough lubrication.
4. The absence of increased requirements for oil quality, the possibility of wide use of mineral, semi-synthetic and synthetic grades of motor oils. It is worth noting that excessive savings on the quality of the oil is reflected in the longevity of the motor.
5. Reduced requirements for the quality of consumed fuel.

The disadvantages of atmospheric power units include the following points:

• large mass of the entire unit;
• increased consumption of gasoline and diesel fuel;
• engine power is less than that of a turbocharged engine with a similar volume;
• the inability to maintain the set power when traveling in mountainous areas, because rarefied air has low pressure there;
• cars equipped with atmospherics have the worst dynamics than their turbocharged counterparts.

Aspirators are relatively cheap and durable motors. Although they are slow-movers, they can’t stand it heavy loads however, their durability has broken all records.

Simplicity and unpretentiousness, low cost of maintenance, infrequent oil changes and other advantages allow us to insist that it is better to use power units of this type. Atmospheric motors enjoy great sympathy among car owners.

Description of turbocharged engines

Unlike atmospheric, turbocharged power units are equipped with additional devices- turbines. In this type of motor, air masses are pumped with the help of a turbine. The direct purpose of the turbine is to pump compressed air into the working cylinders of the engine. In such power units, the combustion chambers have the ability to fill compressed air much larger volume.

Increased oxygen content in fuel mixture results in the following improvements:

• the combustion process takes place more qualitatively;
• motor power increases;
• increased torque;
• improves the dynamics of the car.

The principle of operation of turbocharged engines

Power units equipped with a turbocharger have design differences compared to similar atmospheric engines. The main property of turbocharged engines is the presence of turbochargers in their design. The turbocharger consists of a special fan and a turbine. Compressor connection to exhaust system provides the supply of exhaust gases to the turbine blades.

The pressure of the supplied gases contributes to the spinning of the turbine and compressor fan blades. With the help of the compressor, the gases under high pressure pumped into the combustion chamber.

Additional volume and high blood pressure air to promote complete combustion. air-fuel mixture, which leads to a significant increase in motor power. Conclusion: while maintaining the volume of the combustion chamber, a turbocharged power unit is able to produce more Horse power as opposed to atmospheric.

Intercooler does not replace conventional system cooling and does not even complement it. The intercooler cools the air that heats up in the turbine and reduces its efficiency.

Often this unit is equipped with an additional ventilating mechanism to enhance the cooling effect.

Pros and cons of turbocharged engines

Like any device, a turbocharged engine has certain advantages and disadvantages. To the list of benefits this engine includes the following items:

1. A significant increase in power, as well as engine torque by 70% compared to the atmospheric counterpart, which is the main goal constructive change unit.
2. Reducing the consumption of gasoline or diesel fuel per unit of power.
3. Improved environmental performance exhaust gases due to the operation of the turbocharger, as well as the most complete combustion of the air-fuel mixture in the cylinders.
4. Noise reduction.
5. The versatility of the design of a turbocharged engine, both gasoline and diesel, which allows it to be installed on cars of any brand. Installation of a power unit of this type is possible using the same fasteners.

The main disadvantages of these motors include the following operational disadvantages:

• the complexity of the design, creating difficulties in operation;

• it is necessary to constantly change the engine oil poured both into the crankcase and into the turbine, and also regularly monitor its quality;
• frequent replacement of air and oil filters;
• increased requirements for the quality of gasoline and diesel fuel, which must have a high degree cleaning;
• increase in overall fuel consumption;
• the high cost of repairing a turbocharged engine;
• the need for the engine to idle before shutting down in order to extend the life of the turbine itself.

When evaluating all the pros and cons, the conclusion suggests itself that the efficiency and power of turbocharged engines are significantly higher than atmospheric power units with a similar volume. Owners of cars with such an engine need to carefully monitor the engine of their car.

Only with this ratio is a turbocharged power unit able to provide high efficiency in all modes under any road conditions.

Which engine to choose

When choosing the most suitable model motorists should carefully read design features, advantages and disadvantages of the considered engines. What should be under the hood of a new car, naturally aspirated engine or turbocharged?

If you need a car with better dynamics And high power, That a good option This is a car equipped with a turbocharger. In this case, you will have to face the maximum cost of acquiring quality gasoline or diesel fuel, engine oil, and maintenance costs.

A machine with an atmospheric power unit installed will differ more high resource And inexpensive service. This option is suitable for buyers with a small budget.

An automobile engine is a mechanism that converts some kind of energy into mechanical energy necessary to drive vehicle in motion. The operation of any internal combustion engine is based on the principle of combustion of the air-fuel mixture in a closed chamber. The more air enters the cylinders, the more fuel will be consumed, and as a result, the amount of energy generated will increase. It follows that the power and torque directly depend on the size of the motor.

Atmospheric power unit

Atmospheric engine (AD) is a type of engine that was first created in the days of engine building. It got its name from the very atmosphere that surrounds us and participates in the process of burning the combustible mixture in the engine. BP - the simplest engine without use additional equipment to increase its power.

The atmospheric engine does not have a system for forcing air into the intake system and operates at a pressure equal to atmospheric, sucking in air currents natural way. In other words, the pistons, like a pump, draw in air through the filtration system, and with the help of an injector or carburetor, these air masses mix with the fuel, forming a combustible mixture, which soon ignites. When ignited, the mixture creates energy that drives the working parts of the motor. This way of working has its advantages and disadvantages.

Advantages of a naturally aspirated engine:

1. Increased motor resource. Practice shows that the life of this type of engine can be hundreds of thousands of kilometers before the first overhaul. This is due to relatively small loads. Of course, such a development is possible only under the condition of timely and quality service unit.
2. Simplicity of a design - as consequence, reliability and simplicity of operation, and service.
3. High maintainability. If one or another part of the engine fails, its repair will be relatively inexpensive, which is undoubtedly a huge plus.
4. Less consumption of engine oil, due to the absence of additional parts that require lubrication.
5. No increased requirements for oil quality. It is possible to use mineral, semi-synthetic and synthetic grades of oil, but by saving on quality, you can significantly reduce the “life” of the motor.
6. Fuel quality. An atmospheric engine can process even the most low-grade fuel, but it is highly recommended not to "poison" it, in order to avoid an early breakdown.
7. Longer mileage between oil changes. It changes every 15-20 thousand kilometers and this must be carefully monitored, otherwise the consequences for the engine will be disastrous.
8. More fast warm-up, as opposed to turbocharged.

The atmospheric engine is perfect for a measured and calm pace of driving through city streets.

As for the shortcomings, it can be noted:

1. Less engine power, compared to a turbocharged one, with the same volume.
2. Large dimensions and weight of the unit.
3. Greater fuel consumption than a turbocharged engine.
4. Difficulties when traveling in mountainous areas due to rarefied air and low pressure.
5. Less environmentally friendly to use.

Atmospheric engines are in great demand among car owners due to the previously listed advantages.

For good purging (i.e. filling working mixture and removal of exhaust gases) on modern blood pressure, four valves per cylinder are installed. Two for air intake and two for exhaust. This ensures maximum efficiency and power of the motor.

turbocharged engine

The first turbocharged engine (TD) was invented in 1905, and operated on cars became from the middle of the 20th century. It differs from the atmospheric one by the presence of an additional installed turbine. The function of the turbine is to force air masses into the working cylinders of the engine.

Air intake does not occur naturally, but is stimulated with the help of additional equipment, and therefore the air flows are more voluminous, and more combustible mixture is formed in one intake stroke. A turbocharger, consisting of a turbine and a fan, is connected to the exhaust system, providing exhaust gases to the turbine blades. With the help of a compressor, gases under high pressure are pumped into the combustion chamber. Motor power is significantly increased by increasing the pressure and complete combustion air-fuel mixture. turbocharged engine capable of producing more horsepower than atmospheric, with the same volume.

Turbocharged engines are more revving and can operate at high temperature conditions. To ensure the long operation of the TD, it is necessary to pay great attention to its improvements in the field of lubrication of parts and cooling of the supplied air. In addition to the turbine, a turbocharged engine is equipped with additional device- intercooler, which just solves the problem of overheating. The principle of operation of the intercooler is to use circulating air instead of coolant.

IMPORTANT: the intercooler on the TD is necessary to prevent detonation, in case of engine overheating, due to the intake of an excessively heated mixture into the cylinders.

The advantages of a turbocharged power unit are:

1. Power. Higher than atmospheric due to pressurized air. For the same volumes, turbocharged engine can produce power and torque 70% higher than atmospheric. Actually, increasing power is the main point of modifying the engine design.
2. Small size and weight. Compact in size and easy to use. Suitable for almost any car, and due to the simple design, it can be installed using existing fasteners.
3. Less fuel consumption (relative to horsepower).

These are the three main points that motorists pay attention to in the first place. In addition, the advantage of a turbocharged engine is its high environmental friendliness (due to more efficient combustion of fuel in the cylinders and less harmful substances in exhaust gases). TD makes less noise than BP.

Engine Disadvantages:

1. Increased requirements for fuel quality. Unlike a naturally aspirated engine, a turbocharged one is quite "capricious" and quickly breaks down if you use cheap, low-grade fuel.
2. Increased fuel consumption. Due to the large volume of incoming air, requiring a larger volume of combustible mixture. It is impossible to artificially reduce fuel consumption, because when spinning up, the engine pumps up on its own required level fuel.
3. Increased requirements for the quality of engine oil. Mineral and semi-synthetic are not used, TD requires special oil. Often, the brand of oil that is recommended by the manufacturer has an unreasonably high price. At the same time, the service life of the oil filter is shorter, because. A turbocharged engine has to work at fairly high temperatures.
4. Increased engine oil consumption. Due to the fact that, unlike atmospheric, with a turbocharged engine, the oil changes every 10,000 km.
5. The resource of the turbine is quite small, only about 120,000 km, after which it needs to be replaced, even if the unit was serviced at high level. This is due to the rapid wear of the turbine.
6. Expensive repairs are a fat minus, which plays an important role. Frequent replacement consumables and turbines will significantly hit your pocket.
7. long warm-up and idling, for about 2 minutes, after the end of the trip (a turbocharged engine needs to cool down gradually for longer life).

Observing simple rules on the operation of the TD, it is possible to significantly increase its service life. There are cases when the engines were rearranged and operated on other cars, due to the fact that they remained in working condition, unlike the vehicle itself (the body rotted earlier).

• refuel quality fuel and oil
• Warm up the engine well before driving.
• Control the cooling process
• Timely conduct quality Maintenance unit

IMPORTANT: to install a turbocharger, it is necessary to re-register documents in the traffic police

If we talk about popularity, it can be noted that atmospheric engines are still in the first place. The demand for them is higher, because they have long and firmly established themselves as reliable and easy to operate. On the part of car dealers, preference is also given to atmospherics, since sellers take into account factors such as:

• low quality fuel at gas stations
• insufficiently qualified service specialists in those services

Salons are reluctant to commit to warranty repair cars equipped with turbocharging, but it is impossible to completely exclude their implementation.

Most manufacturers continue to produce cars with simple atmospheric engines, occasionally including models with turbines in the lineup. On Russian roads, mainly by representatives of turbocharged petrol cars, the models German concern VAG: Audi, Volkswagen, Skoda, etc.

Thus, having studied the positive and negative characteristics of atmospheric and turbocharged engines, it can be noted that the choice between them must be made based on the purpose of using the vehicle: for measured and quiet ride quite reliable, massive aspirated. Great for more dynamic rides fit motor equipped with a turbocharger.

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 such 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, combustible mixture It 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 before a major overhaul. And if it is an atmospheric diesel engine, then it is completely capable of traveling a million kilometers. A striking example of this is 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 turbocharged unit was installed on the 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. It uses the energy of the exhaust gases and thus forces air into 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. In addition, the turbocharged engine produces less noise and is more environmentally friendly. In terms of fuel consumption, it practically does not differ from its atmospheric counterparts. Such engines will 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 it's about turbo diesel, 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 the latter engine requires better 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. Oil filter must be of good quality. It depends on resource and wear. important details engine.

About reliability

Which engine is more reliable - atmospheric or turbocharged? Compared to the first, the turbocharged engine is 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. Especially it concerns 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. Can be purchased and diesel engines. 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 repair and diagnostics given 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 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 modern “aspirated” with direct injection.

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.

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 power mechanism a mixture of fuel and air is fed into 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 put into operation thanks to the residual energy that is left behind traffic fumes. 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

The advantages of power turbocharged car units are 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 turbine engines with 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.
