Whether a turbocharged engine is more fuel efficient than a general engine

No, turbocharged engines are much more fuel-efficient than naturally aspirated.

As we all know, automobile engines rely on fuel to be burned in the engine cylinders to output power. In the case of a certain engine displacement, if you want to increase the output of the engine, in addition to providing more fuel combustion, it is to provide more air. Boosting technology is a way to increase the air intake capacity of an engine.

It compresses the gas entering the cylinder in advance by using a special compressor, improves the density of the gas entering the cylinder, increases the air intake, and better meets the combustion needs of the fuel, so as to achieve the purpose of increasing the engine power. There are three main types of engine boosting methods: mechanical supercharging, exhaust gas turbocharging, and compound supercharging.

Exhaust gas turbocharging was used in diesel cars earlier, and domestic sedans began to be used in the Audi 200 with a displacement of 1 8 in 1998, and later there were 1 8T (i.e. turbocharaed, turbocharging) of the Audi A6, until the latest Passat 1 8T. The advantages of turbocharging are obvious, on the basis of not increasing the engine displacement, the power and torque can be greatly increased, and the maximum power output can be increased by about 40, such as 1 8t car is about the same as 2 3 liters of displacement. In addition, the use of supercharging technology improves fuel economy and reduces exhaust emissions.

Of course, after the exhaust gas turbocharging technology is adopted, the maximum burst pressure and average temperature generated by the engine will be greatly increased, so that the mechanical properties and lubrication performance of the engine will be affected. This is the main reason why supercharging technology has not been widely used in gasoline engines until now. Pros:

Without increasing engine displacement, power and torque can be greatly increased. Disadvantages: Turbine operation has hysteresis and high maintenance costs.

The use of turbocharged engines is indeed more and more fuel-intensive, not only the use of turbocharged engines is more and more fuel-intensive, and the current naturally aspirated engine will also consume fuel after a long time, the basis is that the car will cause the car's throttle and spark plug carbon deposits to increase after a long time, and the fuel consumption of the car will rise.

First, the turbocharged engine is indeed more and more fuel-intensive.

For today's cars, most cars use a turbocharged engine. Because the engine is equipped with a turbocharger, this supercharger can input a large amount of air into the combustion chamber of the automobile engine, thereby improving the power output of the engine, but after a long time, the turbocharged engine will consume more and more fuel, the reason is that the carbon deposit on the turbocharger increases, so the legendary air efficiency is not so good, and the fuel consumption of the car naturally increases. <>

2. Relevant basis.

Whether it is an engine with a turbocharger or a naturally aspirated engine, the fuel consumption of the car will increase after being used for a long time, the reason is that the car will cause the carbon deposition inside the engine to increase after driving for a long time, and the carbon deposition generated by the engine will extend to the throttle valve and spark plug of the car. It's even more because of the problems with the car's throttle and spark plugs. <>

3. Summary. In general, the benefit of a turbocharged engine is that it is powerful and accelerates very quickly. However, the biggest disadvantage of this engine is that it is easy to cause carbon deposits in the turbocharger, which will affect the power and fuel consumption of the car.

Therefore, car owners must maintain a good driving habit when driving at ordinary times, so as to reduce the carbon deposition of the car engine. If the owner finds that the fuel consumption of the car has increased and the power has weakened, then the owner should go to a professional auto repair shop in time to clean up the carbon deposits of the engine. <>

The more you use it, the more fuel it consumes. And naturally aspirated engines are all the same. Due to the increasing use time, the internal parts of the engine are aging, which will lead to a decrease in engine power and an increase in fuel consumption.

I think so, but any engine will consume more fuel as it is used, which is an inevitable phenomenon of engine aging.

I think so, turbocharged engines, although more powerful, are more prone to carbon deposits.

Do turbocharged engines cost fuel? Do turbocharged engines cost fuel? Turbocharged engines are not particularly fuel-guzzling and are much more fuel-efficient than naturally aspirated engines.

The following is a more introduction to turbocharged engines: 1. Turbocharged engines are engines that rely on turbochargers to increase the air intake of the engine. It is actually an air compressor, which uses the exhaust gas from the engine as the power to push the turbine in the turbine chamber (located in the exhaust duct), and the turbine drives the coaxial impeller to be located in the inlet duct, and the impeller compresses the fresh air sent by the air filter duct and then feeds it into the cylinder.

When the engine speed increases, the exhaust gas discharge speed and the turbine speed also accelerate, the degree of air compression can be increased, and the air intake of the engine will be increased accordingly, which can increase the output power of the engine. 2. The biggest advantage of this engine is that it can greatly increase the power and torque of the engine on the basis of not increasing the engine displacement. @2019

Turbocharged parts have a life cycle, which is specially marked on the car manual, and the process of replacing turbocharged parts is not only more cumbersome in the process, but also will increase the economic burden of car maintenance in the later stage of the car owner. It's normal to make a fuss, because turbocharging simply adds more pressure to the same cylinder volume, resulting in better power and roll-out torque performance. As the air pressure increases, the gasoline consumption will not be too low.

So relying on turbocharging to save fuel is not realistic.

From the comparison of the working characteristics of naturally aspirated and turbocharged engines, it can be seen that the turbocharged engine effectively uses exhaust gas to do work, increases the intake pressure, and effectively improves the engine power. Judging from the current technical level of turbocharging engine, for example, the power of the engine can be equivalent to even greater power of the naturally aspirated engine using turbocharging. Low displacement, high power and fuel saving, invincible turbo!

This is the real situation advertised by many car companies now, no matter what engine, adding turbo is low displacement, high power, and most importantly, fuel saving. This is somewhat exaggerated, and many small-displacement turbine engines are advertisedLow fuel consumption

Here is the first to explain the turbo fuel saving theory, the turbine fuel saving theory is like this:The turbocharger injects compressed air into the cylinder, so that more air can be drawn in each work process than a naturally aspirated engine of the same displacement, so the combustion is more sufficient, thus achieving the effect of fuel economy and power enhancement. The small exhaust turbo wind blown by Europe focuses on low emissions and low fuel consumption, which is now a trend in the world, as long as it is a mainstream manufacturer, almost all manufacturers can get a turbo engine, and this point has confirmed that their emissions may not meet the standard, as for fuel consumption?

Is the low fuel consumption that manufacturers are focusing on really low?

The turbocharged engine runs at high speed and fuel-saving (the engine noise is smaller than the naturally aspirated noise and the speed is low after the high-speed driving turbine is involved), and the low-speed driving in urban areas is more fuel-efficient than the natural aspiration.

Yes, turbocharged cars are generally more fuel-intensive than powered tans. Of course, I'd go with the Warren car, because it's more motivating.

Personally, I feel that yes, because turbocharged cars will increase the weight of the engine, so it will be more fuel-intensive, and I will not choose it.

It's not a potato digging, it will, and such a car generally has more power in the force, and the speed of the engine is relatively fast, and the gearbox is also very high-energy.

Yes, and they are more powerful, but they will not choose such a car themselves, and the requirements for power are usually not very high.

Reasonable use can save the fuel consumption of the car, the turbocharged engine can provide more sufficient power for the car, in the daily use of the car in the process of the need to pay attention to the use of the turbocharged engine, to avoid abnormalities, affect the normal use.

Attached: Precautions for the use of turbocharged engines:

1. Oil for turbocharged engines

Turbocharged engine needs to choose high-temperature resistant oil, in the performance of oxidation resistance should also have a better performance, when changing the car oil, shorten the cycle, to maintain the oil on the turbocharger lubrication, cooling and other effects. Generally, turbocharged engines will be equipped with oil coolers and air intake system cooling devices to reduce the temperature of the turbocharger and provide a better working environment for the engine.

2. Vehicle start:

The car with turbocharging can not accelerate sharply after starting, especially in a low temperature environment, the engine should be idle for 1-3 minutes, if you are in a hurry to use the car, you can slow down the accelerator after the vehicle starts, so that the engine oil is fully lubricated to the bearing of the turbocharger.

3. Stop and turn off:

The turbocharged engine cannot be turned off immediately after running at high speed, and after the engine is turned off immediately, the amount of oil supplied to the turbocharger bearing will drop sharply, and the turbocharger is still running, and the immediate shutdown may cause damage to the bearing.
