How often does the car clean its throttle?

Generally speaking, the throttle should be cleaned every 20,000 to 40,000 kilometers. If the environment in your car is not good, the cleaning interval should be shortened. It is worth mentioning that maintenance is a good thing, but excessive maintenance will also bring irreversible harm to your car. Excessive cleaning of the throttle will lead to premature scrapping of the throttle. Frequent repeated cleaning will gradually wash away the special coating in the throttle chamber. If the inner cavity loses its coating, it is more likely to cause greasy adhesion, thus forming a vicious circle, and the final result is scrapping.

First of all, let's understand the role of the throttle. The throttle is a controllable valve that controls air to enter the engine. We all know that the air contains dust and sand. When the air passes through the throttle, it will naturally leave impurities on the throttle surface, and together with the engine oil vapor discharged from the crankcase, it will form a black putty deposit.

What's the effect of dirty throttle? First, it must be engine power. Dirty throttle causes the throttle to be inflexible, and the air entering the engine carries a lot of impurities, which affects the normal combustion of gasoline and reduces the working power of the engine. In severe cases, it will lead to unstable idle speed, difficult start-up and power reduction. Finally, after cleaning the throttle, pay attention to resetting the throttle opening. Otherwise, when there is carbon deposit, the on-board computer has already remembered to turn it on. If it is not reset, the engine will have unstable idle speed and overspeed, even more serious than before cleaning. Different vehicle reset methods are different, so I won't introduce them here. If the owner has concerns, it is best to go to a professional repair shop or 4s shop for repair.
