Does the car need to clean the throttle when it travels 20 thousand kilometers?

Does the car need to clean the throttle when it travels 20 thousand kilometers? Does it need to clean the throttle for 20 thousand kilometers? Because the throttle is the throat of the car, the mixture can not be completely burned, and carbon deposition will inevitably appear in the throttle. Since carbon deposition will occur, it is natural to clean it up in time. The throttle is generally cleaned every 20,000 kilometers or so. Throttle is the throat of automobile engine, which controls the air intake of zd automobile engine, and the driving computer judges the fuel injection quantity according to the value of air flow sensor. Therefore, the accuracy of throttle intake is related to fuel injection. It is the premise of stable operation of automobile engine. So the version of the accelerator pedal we step on actually controls the throttle opening, not the throttle. The air in the engine needs to pass through our throttle, which is easy to accumulate dust. When there is too much dust, the air entering our throttle will be blocked by dust, resulting in less air actually entering the engine at the same opening. Therefore, in this case, we need to clean our throttle to ensure that our throttle can accurately empty the air entering the engine. Too dirty throttle will lead to power decline, unstable idle speed, and serious engine failure lights. Therefore, it is necessary for us to clean the throttle regularly. @20 19
