Is it necessary to clean the car throttle?

Automobile throttle needs to be cleaned regularly, and it is generally recommended to clean it when driving 20,000 km to 30,000 km. First of all, we should understand the function of the throttle valve-the control valve that controls air to enter the engine. Because the air contains dust and sand, when the air passes through the throttle, it will leave impurities on the surface of the throttle, and together with the oil vapor brought by the crankcase, it will form a black oil-gray deposit. Second, the dirty throttle will cause the throttle to move slowly, and many impurities will be involved in the air, which will affect the normal combustion of gasoline and reduce the working power of the engine. In severe cases, it will lead to unstable idle speed, difficult start-up, decreased power and even failure. Thirdly, if your vehicle is in a harsh environment (such as driving in a desert or a dirty city), the cleaning interval should be shorter. By the way, maintenance is a good thing, but excessive maintenance will bring irreversible damage to your vehicle. Frequent cleaning of the throttle valve will lead to its early retirement. Excessive cleaning will gradually remove the special coating of the throttle chamber. Once the inner cavity coating is lost, it is easy to cause greasy adhesion and form a vicious circle. Eventually, the throttle will be abandoned.
