Cause and analysis of cleaning throttle valve failure

Throttle failure is largely caused by carbon deposition in the throttle, and the inside of the faulty throttle is full of black carbon powder produced by insufficient combustion. The long use of the accelerator and the poor driving habits of the owner are all reasons for carbon deposition.

Throttle failure usually leads to:

1, the car can't start, or after starting, step on the accelerator and the accelerator won't return.

2, black smoke, high fuel consumption.

3. The idle speed is too high and the acceleration is not smooth.

Throttle is a control component that controls the intake of engine, and adjusts the mixing ratio of gasoline and gas according to computer signals, so that gasoline can be fully burned and power can be generated. In fact, every time the driver steps on the accelerator, he is not stepping on oil, but "gas". By stepping on the accelerator and shifting gears, a certain amount of air is forced into the engine.
