Turbocharged or naturally aspirated engine. What is better and more reliable, also a few words about consumption

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 varieties automobile motors have as their undeniable merits, and, of course, a number of shortcomings. Therefore, it is impossible to give a definite answer which engine is better. In our article, we will try to give a comparative description of the main technical and consumer indicators of both motors.

Briefly recall how a gasoline engine works:

• The air-fuel mixture enters the cylinder through the intake valve.
• 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

To say that atmospheric (that is, standard) and turbocharged engines is fundamental different motors, it is forbidden. 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 special device- 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 the exhaust manifold to 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, a special radiator is installed between the compressor and the intake manifold - an 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 in one cycle. fuel mixture, which means more energy is released. It is due to this that they significantly exceed atmospheric counterparts in terms of power.

For information! Since all internal parts of 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. Under the right operating conditions and proper care, the “life” of atmospheric engines is 2–4 times longer than that of turbocharged engines: 300,000–400,000 km are often not the “longevity” limit 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) motor oils. However, one should not forget that what better oil the longer the life of the motor.
• 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 atmospheric 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 over a wide rev range, 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 you to most rationally position the power unit and reduce total mass vehicle, 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 due to more complete combustion of 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 consumption oil, as the turbine bearings heat up to very high temperatures during operation.
• The need to use only special high-temperature synthetic oils.
• More frequent frequency oil change (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 is significantly inferior to turbocharged 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 naturally aspirated engine with a volume of 2.0 liters or turbocharged engine volume of 1.4 liters. In the urban cycle, the consumption of a 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 the normal operation of a 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, a quick start from a standstill, 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.

Choosing new car, it is recommended that you familiarize yourself with the technical specifications and operational features offered well-known manufacturers. The article presents naturally aspirated engine, which is very popular among motorists due to its numerous advantages. There is no turbocharger in the design of the power unit, air-fuel mixtures are formed using a pressure equal to one atmosphere.

What is a naturally aspirated engine

Not all car owners understand what a naturally aspirated car engine means. These are gasoline engines of a classical design, which pump air from the surrounding space using carburetor pistons. With uniform mixing of oxygen with atomized gasoline particles, fuel mixtures are formed. They are used for combustion in the combustion chamber of a gasoline engine.

The principle of operation of the atmospheric engine:

1. The suction of air from the atmosphere.
2. Mixing with gasoline vapors in the proportion: gasoline - 1 part, oxygen - 14.
3. Feeding the mixture into the combustion chamber.
4. Volume expansion.
5. Piston pressure.
6. Transmission of rotation to the crankshaft.

The effect of suction of air masses occurs due to the creation of a rarefied atmosphere in the cavity of the intake manifold.

What is the difference between a naturally aspirated engine and a turbocharged engine?

It is known that the quality of fuel combustion and the amount of energy pushing the pistons depend on the volume of air supplied to the cylinders. The larger the motor, the more power and develops the atmosphere.

Unlike turbocharged engines, atmospheric engines do not provide for the forced retraction of air flows under pressure. Atmospherics are characterized by reliability, they are resistant to detonation. Thanks to the use of lubricating fluids made on synthetic basis, losses to overcome friction forces are significantly reduced. Due to the improvement of the valve timing adjustments, ultra-precise fuel injection is carried out under the control of an electronic system.

In order to improve specifications engine, models with cylinders of large working volumes in the amount of 6 to 12 pieces are used. However, an increase in volume in the engine building industry is not always considered appropriate, since this leads to a heavier structure.

Pros and cons of naturally aspirated engines

With the advent of powertrains equipped with a turbocharger, many drivers began to give preference to turbocharged vehicles. However, there are many motorists who, when asked which engine is better naturally aspirated or turbocharged, choose the familiar classic option, based on the following advantages:

1. Long service life.
2. The simplicity of the device.
3. Absence serious problems during operation.
4. Availability of repair and Maintenance with your own hands.
5. Reduced consumption engine oil.

atmospheric engines internal combustion differ most long run. There are cases when cars with installed atmospherics work without major repairs along the way, more than 500 thousand kilometers. The only condition is timely care and regular replacement engine oil with filters. Their parts and assemblies are resistant to wear. The reliable naturally aspirated motor has an increased motor resource and continues to work even after repeated replacements of the car body.

Thanks to uptime atmospheric engine and ease of operation, it is unpretentious to the quality of fuel and lubricants. With regular use of low-quality gasoline, such engines, if they fail, restore their performance faster. The main requirement for engine oil is to provide required level. Replacement lubricating fluid should be carried out every 15 - 20,000 km. When choosing the most suitable brand engine oil for an atmospheric engine, it is recommended to give preference to synthetics or semi-synthetics.

Interesting: Unlike a turbocharged engine, here you can fill in and mineral oils if it was not possible to purchase better lubricants.

The simplicity of the design of the aspirator makes it possible to produce some repair work even in garage conditions. When contacting a car service, the cost of services is several times lower compared to repairing similar malfunctions of turbocharged engines.

Atmospheric internal combustion engines have some disadvantages:

1. Relatively large weight of the mechanism.
2. Reduced power and developed torque in comparison with a motor equipped with a turbine.
3. Aspirators are not designed to work under heavy loads.
4. Difficulties in operating high altitude under rarefied air conditions.
5. When the atmospheric engine is running at low speeds, it is not always absorbed enough air, which affects the stability of work.

Examples of vehicles with powerful naturally aspirated engines

• Mercedes C 63 FMG Coupe Edition 507.
• Chevrolet Corvette C 7 Stingray.
• Jeep Grand Cherokee S.R.T.
• Audi RS5.
• Audi RS4 Avant.
• Chevrolet Camaro.
• Mercedes SLK 55 AMG.
• Porsche Cayenne GTS.
• Infiniti QX70.
• Lexus LS460.
• Mercedes-Benz OM 602.
• OM 612.
• OM 647.
• BMW M57.

What is better naturally aspirated or turbocharged engine

There is no single answer to this question. Each of the presented motors has its advantages and disadvantages. To understand whether a naturally aspirated or turbocharged engine is more suitable for you, it is recommended that you familiarize yourself with the features of their operation.

Unlike atmospheric, turbocharged power units have an essential feature: air is not sucked in here, but is forcibly pumped with the help of installed turbine. At the same time, such characteristics of the motor as torque and power are significantly improved.

Many drivers want to improve the dynamics of the vehicle, as a result, they have a natural question whether it is possible to put a turbine on an existing naturally aspirated engine and, if so, how to do it.

This possibility exists, it all depends on the model of your car. There are situations when it is more profitable to get a new car than to purchase expensive parts for chipping and pay for the work of masters. To install a turbine on a naturally aspirated engine, it is necessary to invite a qualified mechanic with experience in such work.

Diesel engines equipped with turbocharging are called turbodiesels. The composition of the turbocharged power unit includes a turbocharger, which pumps air into the diesel intake manifold under high pressure.

Interesting: Unlike atmospheric diesel engines, when operating in high mountain conditions, turbodiesels provide the most complete combustion of fuel. Among experts, this effect is known as the "altitude of the car."

Strengths and weaknesses of turbocharged engines

These power units are usually compared with conventional aspirated. The main advantages of engines equipped with a turbocharger:

1. Such motors are characterized by increased power characteristics.
2. Develop increased torque.
3. They don't make a lot of noise while working.

Along with the advantages, motors with turbines also have disadvantages:

• increased requirements for the quality of gasoline, diesel fuel, motor oils, which makes it necessary to buy products of expensive brands;
• work in conditions elevated temperatures leads to a reduction in the service life of fuel, oil filters, drivers have to regularly check the level of lubricants, monitor the degree of contamination of the filter elements in order to prevent the failure of expensive units (compressor, etc.);
• increased fuel consumption;
• relatively short service life;
• high cost of repair and maintenance;
• difficulties in choosing an auto mechanic with the necessary knowledge and experience.

Atmospheric and turbocharged engines have positive and negative qualities. Before installing a fashionable turbo engine on a car, it is recommended to make sure that such tuning is appropriate. When making a decision, it is necessary to assess the condition of the roads, the cost quality gasoline etc.

Often, car buyers are faced with concepts such as "aspirated engine" or "turbocharged engine" (sometimes there are "forced engines").

From this article you will learn:

It even happens that the buyer finds out about the type of motor immediately before himself, not realizing that each engine has its own operating characteristics, which it is important to know about even before the buyer gets behind the wheel.

Fundamental differences between engines

The atmospheric engine is a "normal" internal combustion engine, the design of which was developed a long time ago and brought to its perfection over many decades of operation.

A turbocharged engine is the same internal combustion engine, in the design of which a turbine has been added that pumps air into the cylinders under pressure, which significantly increases the power of the engine. A small turbocharged engine (eg 1.3 liter turbo - 140 hp) can have the same power as a noticeably larger aspirated engine (1.8 liter - 140 hp).

The forced engine is the same internal combustion engine, but having a rather complex design, often involving the use of racing technologies, expensive materials and all kinds of mechanisms for extracting maximum power. It can be equipped with a turbine or not. The design of a boosted engine often implies that high engine power is at the expense of a resource (forced engines do not last long).

Each type of engine has pros and cons that determine a number of requirements for the operation of such an engine.

atmospheric engines

The disadvantages of atmospheric engines usually include their "outdated" design, low power per unit volume, as well as relatively low efficiency (as a result of which harmful emissions increase).

However, the atmospheric engine has one very serious plus, which in Russian conditions operation, often outweighs all the disadvantages - this is high reliability.

The design of the aspirated engine is quite simple (in comparison with a turbocharged and forced engine), in such an engine, after many decades of improvements and improvements, there are practically no parts left that can break.

Latest significant changes in the design of atmospheric engines, which significantly increased power and reduced fuel consumption, occurred in the 80s and 90s of the last century. Since then almost all automotive manufacturers make changes to the design of their atmospheric engines only for the sake of reducing harmful emissions.

Due to its simplicity and reliability, the naturally aspirated engine has another significant advantage - unpretentiousness. An atmospheric engine is much easier to endure operation on poor gasoline (which is not uncommon in Russia) than a turbocharged or forced engine. This feature is very relevant for owners on whom such engines are most often installed.

turbocharged engines

As for the engine with a turbine, it has many disadvantages that the dealer does not talk about when selling the car.

The disadvantages often include the complexity of the engine design (as a result, breakdowns occur more often), the relatively short service life of the turbine (due to permanent job at high temperatures), Not high resource the engine itself (due to operation at increased loads).

Also, the disadvantages include high flow fuel (during intensive driving), exactingness to its quality, the presence of a "turbo hole" during acceleration, which many models of turbo engines have, a large number of difficulties in operating and maintaining the turbine (installing a turbo timer, using special oils etc.).

Another significant disadvantage is the high oil consumption, which is the norm for many turbo engines.

Among other things, a turbocharged engine requires highly skilled craftsmen for maintenance and repair. Many car owners neglect this fact, giving the car to "omnivorous" services, after which the engine life can be significantly reduced.

The advantages of a turbocharged engine, in turn, include a fairly high power with a relatively small volume. This allows manufacturers to:

• - firstly - to achieve relatively low flow fuel in urban driving and reduce harmful emissions (which corresponds to environmental regulations Euro-4 and Euro-5 and others).
• - secondly, to install small engines on a relatively heavy vehicles(business sedans and SUVs).

Connoisseurs also attribute the unique driving pleasure and characteristic whistling sounds during acceleration to the advantages of turbo engines.

Forced engines

The pros and cons of boosted engines are often similar to the pros and cons of turbo engines.

The disadvantages include the complexity of the design (as a result, breakdowns occur more often), the demands on fuel quality and the low overall engine life.

Forced engines are also demanding on quality repairs and can consume quite a lot of oil.

The advantages of a forced motor can also include a fairly high power with a relatively small volume, which allows manufacturers to achieve low fuel consumption in the city and reduce harmful emissions. Due to their high power, such engines can also be installed on heavy vehicles.

Exploitation

The cost of running an engine (and the entire vehicle) typically depends on the complexity of that engine's design.

If the engine has a complex design (turbocharged or forced), then for its normal operation, high-quality fuel is required (the risk of filling bad gasoline large in Russia), quality (fakes famous brands there are many on the market), as well as qualified service, which is quite expensive.

An engine with a complex design is more likely to break down, and spare parts for such an engine are quite expensive.

The opposite is also true - the simpler the design of the engine, the less money the owner has to spend to maintain its normal operation (cheaper spare parts, easier service less chance of breakage).

Progress and wallet

The recent trend is such that almost all automakers, in an effort to increase engine power and at the same time reduce its consumption, are switching to the production of cars with turbocharged or forced engines of small volume.

This approach makes it possible to produce sufficiently powerful and green cars, but at the same time quite complicates the design (which leads to more frequent breakdowns), and also reduces the resource.

For the buyer, this approach is a plus until he begins to deal directly with the repair - that is, until the end warranty period. After that, a car with a turbocharged or boosted engine may well become a headache for its owner.

Of course, most buyers of a new car tend to drive it just before the end of the warranty period, after which they sell it.

However, any buyer of a used car will calculate in advance their possible costs for this car and will not pay a lot of money for a car whose engine life will be in some doubt.

Therefore, in order to sell used a car with a turbocharged or boosted engine of a small volume, sellers will most likely have to lose more money in money than when selling the same car, but with a normal-volume naturally aspirated engine, the resource of which is initially longer.

Thus, technical progress for any car owner in Russia will have its own cost - for the owner new car it will be the amount of loss on a subsequent sale, and for the owner of a used car - the amount of maintenance costs and more expensive repairs.

Motorists are faced with the question of which car to give preference to, a naturally aspirated or turbocharged engine should be installed on it, which would be better for a 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 atmospheric engine is characterized by a simple structure, which greatly facilitates repair work, reduces time 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. Reduced consumption of engine oil, as 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 low-speed, they do not withstand 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 with 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.

An increased oxygen content in the fuel mixture leads to an improvement in the following characteristics:

• 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, gases under high pressure are pumped into the combustion chamber.

Additional volume and high blood pressure air contribute 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 generate large quantity Horse power as opposed to atmospheric.

The intercooler does not replace the conventional cooling system 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 idling before shutting down to prolong 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 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 costs for the purchase of high-quality gasoline or diesel fuel, engine oil, as well as the cost of maintenance.

A machine with an atmospheric power unit installed will have a higher resource and low-cost maintenance. This option is suitable for buyers with a small budget.

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 same 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 the field believe that turbocharged engine- This 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, switch 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 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 we take a 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 a complete 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 make even more changes to the engine design every year than reduce its potential reliability;
• many companies have pursued 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 of car 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 on sale 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 characteristic of an engine with a turbine, it is possible to use the unit at high speeds without loss of efficiency;
• 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 official station, since 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 consumption in urban conditions, and the need to create large-volume 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 meet high quality standards. 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 successful solution for use in the northern regions of the country;
• atmospheric units are able to operate at low temperatures and cope well with not very 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 to see short video about how turbocharging works in a powertrain:

Summing up

Today, a technological engine can be called a unit with a minimum volume and an excellent power indicator. Manufacturers squeeze more and more more possibilities power from the simplest power units, installing turbines and various automation 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 high-tech units and excellent high technologies are still a controversial advantage for our country. 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?
