How many kilometers is the throttle usually cleaned?

Generally, the throttle is cleaned every 40,000 kilometers.

The specific information of throttle valve is as follows:

Throttle is a controllable valve that controls air to enter the engine. There are two kinds: traditional cable throttle and electronic throttle. After the gas enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, which will be burned to do work. It connects the air filter and the engine block, and is called the throat of the automobile engine. Whether the acceleration of a car is flexible is closely related to the cleanliness of the throttle.

Fault handling

Hard fault: The resistance part of potentiometer is made by spraying a layer of carbon film on polyester substrate, which is actually a very low-level preparation process with low wear resistance. To put it bluntly, it is not as good as the potentiometer of our usual household appliances. The sliding contact consists of a row of opposing claws made of fine steel. Pay attention to the claw! This is simply worse! In addition, there is no protective agent on the carbon film, and the falling carbon powder leads to poor contact, which is inevitable.

Soft fault: people are often troubled by cleaning the throttle because the throttle is too low most of the time. Air flows through the gap of the throttle at high speed (tens to hundreds of meters per second), and the influence of dust on the airflow exceeds the adjustment ability of the throttle.
