Automobile throttle is a controllable valve to control 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.

Clean the throttle valve at ordinary times, otherwise it will be easily damaged.

Cleaning cycle of throttle valve: The change of throttle valve use status mainly depends on factors such as dry air quality, air filter status, vehicle use environment, driver's driving habits and so on.

Because the cycle of cleaning the throttle of a vehicle cannot be judged by mileage alone, the interval between the first cleaning of the throttle must be the longest when buying a vehicle.

After that, with the factors such as crankcase ventilation and oil and gas condensation in the intake pipe, the cleaning frequency will become more and more dense.
