How many kilometers does the car throttle have to be cleaned?

1. Clean the car throttle every 20,000-40,000 kilometers. Throttle is a controllable valve to control air to enter the engine, which can be vividly described as a "throat" engine. After the gas enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, and the combustion is successful. The depth of the owner's stepping on the accelerator can determine the size and fit of the engine power through the throttle opening. 2. There are two ways to clean the throttle valve, namely, disassembly-free cleaning and disassembly-free cleaning. Without disassembly and cleaning, spray the accelerator cleaner directly on the wiping cloth or accelerator, and then scrub the accelerator. Disassembly and cleaning need to remove the whole throttle assembly, and then clean it thoroughly with special cleaning agent before recycling. Million car purchase subsidy
