How long does it take to clean the throttle of the automobile engine nozzle?

It is best to clean the throttle of automobile engine nozzle every 20-40 thousand kilometers. Clean the throttle as often as possible. Excessive cleaning will slowly clean off the special coating of the throttle inner cavity, and the inner cavity will lose the coating, which is more likely to cause greasy adhesion, accelerate the aging of the throttle or increase the throttle load. If the throttle is not cleaned for a long time, carbon deposition and impurities will affect the accuracy of the throttle opening, and air containing impurities may also enter the combustion chamber, which will affect the normal operation of the engine. The most obvious performance is the unstable idle speed, the feeling of sudden oil collection during normal driving, the power will be worse than before, the fuel consumption will also increase, and sometimes there will be problems such as difficulty in starting.
