Is it necessary to clean the throttle?

Throttle cleaning is necessary. Why do you say that? 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 surface of the throttle, together with the engine oil vapor in the crankcase, thus forming black putty deposits.

What's the effect of dirty throttle? Engine power must be the first to bear the brunt. 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, there will be failures such as unstable idle speed, difficult start-up and power drop.

Generally speaking, clean the throttle every 20,000-40,000 kilometers. If the environment in your car is bad, the cleaning interval will 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, and frequent cleaning will lead to the gradual cleaning of the special coating in the throttle cavity. If the inner cavity loses its coating, it is more likely to cause greasy adhesion, thus becoming a vicious circle, and the final result is scrapping.
