Turbocharger is a very important part of the car, it can improve the operation of the engine, make the car more powerful, so what is the precursor of turbocharger failure?

1. Blue smoke comes from the exhaust pipe of the car. Because there is a gap in the turbocharged blade axle, resulting in poor sealing, so there will be blue smoke when driving, or at idle.

2. The fuel consumption of cars increases. Due to the blockage of the exhaust gas circulation pipeline in the engine, the exhaust gas can not be discharged smoothly, which leads to the increase of fuel consumption, not only gasoline consumption is fast, oil consumption is also fast.

3, the engine has abnormal sound. Because the piston ring and other parts are seriously worn, or the parts are aging, the engine will have abnormal sound when driving, and the exhaust pipe will emit a lot of blue smoke.

4. There is abnormal sound when refueling or receiving oil. Because of the rupture of the air duct in the turbocharger, there will be abnormal sound when refueling or collecting oil. In these cases, it is necessary to go to the 4S shop for maintenance in time.

What happens when turbocharger fails

1. The composition of turbo-mechanical supercharger is very complex. If there are some problems with the wheel shaft through the sealing system, the car will take blue smoke when working at idle, and the more obvious it is when the weather is cold.

2. If the exhaust pipe is blocked, it will not only emit blue smoke, but also greatly increase fuel consumption. The car's power was noticeably reduced, and from time to time it made a strange engine noise.

3. The air duct of the turbocharger is broken, which will lead to obvious abnormal sound when refueling or collecting oil. After a long time, it will be found that the development power continues to decline.

4. Fuel burning is also a common phenomenon, which is reflected in blue smoke.

5. After the turbocharger is bad in the society, we will also cause the engine jitter.
