When the throttle oil circuit is cleaned for 20,000-40,000 kilometers, the valve should not be cleaned at will, and the cleaning frequency should not be too much. Excessive cleaning will lead to the gradual cleaning of the special coating of the throttle inner cavity, and the inner cavity will lose its coating, which will easily lead to greasy adhesion. The cleaning frequency of throttle valve depends on the quality of air filter, the quality of engine oil used, the condition of driving section, air temperature, working temperature of engine, driving habits and so on. Throttle is a controllable valve that controls air to enter the engine. There are two kinds: traditional cable throttle and electronic throttle. After the gas enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, which will be burned to do work. Known as the throat of an automobile engine, it is connected with the air filter and the engine block.
