How often do you clean the throttle of turbocharged engines?

Under normal circumstances, the throttle valve is cleaned once every 20,000 kilometers. If it is used in harsh environment, for example, it is often driven in areas with serious air pollution below 1000 km. Function of throttle: 1. Throttle is a controllable valve that controls air to enter the engine. We can vividly describe the throttle as the "throat" of the engine. After the gas enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, thus the combustion is successful. The depth of stepping on the accelerator determines the size and fit of engine power through the throttle opening; 2. There are two ways to clean the throttle, namely, disassembly-free cleaning and disassembly-cleaning, each with its own advantages and disadvantages. The biggest feature of disassembly-free cleaning is that it is simple and convenient to spray the accelerator cleaning agent directly on the wiping cloth or directly on the accelerator and then scrub the accelerator. The disadvantage is that the cleaning effect is generally suitable for throttle valves that are not particularly dirty; 3. Dismantling and washing is very troublesome. Before recovery, the whole throttle assembly must be removed and thoroughly cleaned with special cleaning agent. Although the steps are cumbersome, the advantage is that the cleaning effect is thorough, but the price is more expensive.
