Throttle refers to the throttle valve, which means:

Throttle is a controllable valve that controls air to enter the engine. After the air enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, and the combustion is successful. It connects the air filter and the engine block, and is called the throat of the automobile engine.

Throttle four-stroke gasoline engines are generally like this. Throttle is one of the most important components in EFI automobile engine system. Its upper part is the air cleaner grille, and the lower part is the engine body, which is the throat of the automobile engine.

Common faults of throttle valve:

1, hard fault

The resistance part of potentiometer is formed 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 ordinary 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.

2. Soft fault

People often worry about cleaning the throttle, because most of the time the throttle is too low. 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.
