How often is the electronic throttle cleaned?

If you drive for a long time, dust will accumulate on the accelerator. This may lead to insufficient air intake of the engine, unstable idle speed of the engine, feeling that the throttle is suddenly received during driving, and the power is reduced. In severe cases, it may also cause problems such as difficult start-up and increased fuel consumption. There is no specific time limit for the cleaning frequency of the throttle valve, and it is usually cleaned after the above symptoms appear. It is generally recommended to clean once every 20,000 ~ 40,000 kilometers, but this is only a reference value. The specific cleaning cycle also depends on the air environment of the personal car, the type of oil used, the replacement interval of the air filter and the operating habits. For example, when driving on dusty roads, the throttle is easy to get dirty, and it may need to be cleaned less than 20,000 kilometers. The electronic throttle usually needs to be cleaned about 20 thousand kilometers, but it still has a lot to do with the habit and environment of the car. If the idle speed is unstable, you should consider cleaning the throttle or electronic throttle. Electronic throttle is an important control part of automobile engine, which consists of engine, speed sensor, throttle and so on. It can not only accurately control the throttle opening, improve fuel consumption and reduce emissions, but also obtain satisfactory handling performance, realize the integration of idle speed control, cruise control and vehicle stability control, and simplify the structure of the control system.
