How much does it cost to clean the throttle? How long does it take to clean the throttle?

The price of cleaning the throttle valve in Changan Ounuo is generally around 300 yuan, and the throttle valve is generally cleaned once every 40,000 kilometers. Throttle is a controllable valve that controls air to enter the engine. After the air enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, which will be burned to do work. It is connected with the air filter at the top and the engine block at the bottom, and is called the throat of the automobile engine.

The throttle valve belongs to the intake area. At present, the work of each piston of the engine is not synchronous. When the engine is turned off, the intake valves of some cylinders cannot be completely closed, and some unburned fuel is continuously vaporized and oxidized, which will produce some carbon deposits at the intake, especially behind the throttle. On the one hand, these carbon deposits will block the idle channel and make the throttle stuck or beyond its adjustment range; On the other hand, they will make the pipe wall of the intake pipe rough, and the intake will produce eddy currents in these rough places, which will affect the intake effect and the quality of the mixture, resulting in idling jitter, poor speed increase, flameout and fuel consumption.
