Is the 1,4t engine life good?

In all kinds of rumors about turbocharged models, the saying that "sooner or later you have to change the turbo" really scared off many people, especially when someone comes up with a replacement cost of 10,000 yuan and a "terrible" example of replacing the turbine to 60,000 kilometers to scare you, it makes people feel that "although the turbo is good, we can't afford to raise it!" In fact, the truth is anything but so! As a part of the core components of the car, the turbine is not a wear part that needs to be updated frequently, and such a design cannot be passed in the engineering development stage!

The probability of turbine damage is no different from other parts, and, under today's TSI technology, the turbocharger has been integrated into a component with the engine exhaust system, which can not be replaced separately as before, and there are currently more than 2.5 million models with TSI technology in the world, and the failure of the turbine is minimal, in other words, now we choose TSI models, in the entire life cycle of the vehicle, the turbo is one of the most reliable components, as long as it is used normally, there is no need to pay special attention to it, The turbine does not need to be replaced or maintained throughout its life cycle, and "it can be used when it is not there, but it is absolutely on call when needed" is an important feature of the new generation of exhaust gas turbines.

The current manufacturing process, the life of the engine is not much different, and it is no problem to drive it for 10 years at home.

The life of the engine is very long, because of the EA111 engine.

The turbocharger uses an independent cooling system, and the turbocharger can be replaced as long as it is maintained normally.

Turbocharger:

A turbocharger is actually an air compressor.

The air intake is increased by compressing the air. It uses the inertial impulse of the exhaust gas discharged by the engine to push the turbine in the turbine chamber, and the turbine drives the coaxial impeller, and the impeller is pressurized by the air filter.

The air sent from the pipes pressurizes it into the cylinder. When the engine speed increases, the exhaust gas discharge speed and the turbine speed also increase synchronously, the impeller compresses more air into the cylinder, and the pressure and density of the air increase can burn more fuel, and the corresponding increase in fuel volume and adjust the speed of the engine can increase the output power of the engine.

Finish. Volkswagen Speed.

Volkswagen's engine in the normal use process, the general maintenance to keep up, 300,000 kilometers is no problem, that is, the home use cycle is no problem, but the supporting DSG may fail.

Hello, the engine turbocharger, the general service life mainly depends on the driver's driving habits and the maintenance of the vehicle, if both are good, 100,000 kilometers should be no problem.

The life of the engine mainly depends on the operation of the driver, as well as the maintenance of the vehicle.

The service life of the turbo engine of the Volkswagen turbo engine is basically the same as that of the engine, and the turbo will not have problems using 20-300,000 kilometers.

If not properly used or maintained, the turbine will have problems. Turbocharged engines have high oil requirements, and turbochargers are also lubricated by oil to dissipate heat. When the turbocharger is working, its speed can reach more than 100,000 revolutions.

Therefore, this puts forward high requirements for engine oil, and when the turbocharged engine is working, the pressure and temperature in the cylinder are relatively high, so it is also necessary to use better engine oil. Engine oil is known as the blood of the engine. It plays the role of lubrication, cleaning, sealing, heat dissipation, buffering, and rust prevention in the engine, so it is very important for the engine.

Turbocharged engine to use correctly:

1. After the engine starts, you can't start immediately or slam the throttle. Generally, it is necessary to idle for 3 minutes, especially in winter, and it is necessary to warm up the car for at least 5 minutes, so that the oil temperature rises, the flow performance becomes better, and the lubricating oil fully lubricates the rotor bearing before the supercharger rotor runs at high speed.

2. The engine cannot be turned off immediately when it is hot (the engine without a separate supercharger cooling system is installed). The rotor bearings of the turbocharger are lubricated and cooled by a certain pressure of oil. If the engine in the hot engine state suddenly stops, the oil pressure will decrease rapidly, and the temperature of the turbocharger turbine will rise rapidly.

3. After the engine suddenly turns off, the heat on the exhaust manifold will be absorbed into the turbocharger housing, and the oil staying inside the supercharger will be boiled into carbon deposits, blocking the oil inlet, resulting in the lack of oil in the bearing, and accelerating the wear between the turbine shaft and the pure bearing. Therefore, the engine should be idle for 3 5min before turning off, so that the temperature of the turbocharger and the speed of the rotor will decrease.

4. It is strictly forbidden to use the operation method of "acceleration-flameout-neutral slippery rough and noisy", because the engine suddenly stalls at full load and high temperature, the oil pump stops working, and the lubricating oil cannot take away the heat of the parts in the supercharger, which will lead to damage to the supercharger.

The turbocharged engine can be used for about 100,000 kilometers, and it can reach 200,000 kilometers with frequent maintenance

1. First of all, the original life of the design, the working environment of the turbine is basically 900 to 1000, and the speed of the turbine can reach 180,000 to 200,000 revolutions per minute under the condition of full hail load;

2. The previous materials are not very up-to-date, and they will age after a long time, resulting in various other situations such as detonation, lubrication jamming, burning, etc., basically 8 to 100,000 kilometers to be replaced;

3. Now the turbocharged engine can basically maintain about 150,000 kilometers.

First, the form of the engine.

It is a vortex supercharged engine, in which the vortex supercharger can increase the air intake; It is an ordinary naturally aspirated engine with no device for a forced increase in air intake.

Second, the power is different.

The car is equivalent to the displacement of ordinary self-priming, the larger the displacement, that is, the more power is output.

The engine can achieve the power output of the displacement through the supercharger according to the displacement, which is more fuel-efficient and environmentally friendly. The ordinary one is much worse than the relative engine.

Third, the time required to start is not the same.

The acceleration power of the engine is more difficult and lagging than that of ordinary engines. For example, when stepping on the accelerator, the acceleration response of the engine model is slower than that of the ordinary engine model.

Fourth, the acceleration is different.

The displacement of the engine is much more than the displacement of the ordinary engine, such as the displacement of the model in the straight line acceleration faster than many displacement cars, but in the power does not exceed the many displacement of the car.

Fifth, the maintenance cost is different.

It is not turbocharged, so the power is weaker than the power with turbocharging. However, in terms of maintenance costs, it is much cheaper. The reason is also very simple, adding an extra set of equipment will increase the cost and the probability of failure.

Adding T proves more turbocharged. The displacement of this Nainen car has surpassed many displacement cars in terms of torque, that is to say, the Bora is faster than many cars in straight line acceleration. But in terms of power, it does not exceed the car of many displacements.

Therefore, there will be a gap in the top speed. Models that are not as good at high-speed acceleration (over 180 yards). Here's a quick run:

It's not that the bigger the displacement, the faster the car. For the speed of the car we should be understood in two aspects: the first power, power is horsepower, which can be simply regarded as the standard of maximum speed, because the car with small horsepower can no longer overcome wind resistance at top speed.

That's why high-horsepower cars are extremely fast. Second: Torque Torque can be understood as explosive force, the greater the torque The faster the straight line acceleration, the stronger the push back feeling.

The torque is 220 and can be reached at 1750 rpm, so many cars can't run at the start or acceleration.
