How long does it take to clean the valve?

Usually about 2 hours, removing carbon deposits can improve the accuracy of air intake and fuel injection, improve fuel consumption and prolong engine life. Throttle is a control valve that controls air to enter the engine. After the air enters the intake pipe, it is mixed with gasoline to form a combustible mixture, which is burned to do work. It connects the air filter and the engine block, and is called the throat of the automobile engine. In order to keep the throttle clean, it usually takes about an hour to clean it. Cleaning has the following two functions: 1, removing carbon deposit, improving intake and fuel injection accuracy, improving fuel consumption and prolonging engine life. 2. Failure to clean the throttle for a long time will lead to the wrong throttle opening, and impurities in the air will enter the combustion chamber of the engine. Both of these conditions will lead to abnormal engine, mainly manifested in unstable idle speed, sudden opening of throttle valve and power reduction during operation.
