What is the function of the throttle?

The main function of the throttle valve is to control the air intake according to the load of the engine. The throttle valve is installed on the engine to control the amount of oil entering the cylinder for combustion (commonly known as throttle valve). The greater the opening, the more mixed gas enters the cylinder and the higher the engine speed, thus controlling the engine speed.

Throttle is divided into electronic type and cable type. The so-called dirty throttle mainly refers to the sludge and carbon deposition on the turntable, turntable shaft and the inner wall of the throttle. Dirty will lead to idle jitter, when driving, the idle speed will suddenly rise and it will not come up, and the oil collection reaction will be slow. Sudden acceleration will have backfire sound. If the cable-type throttle bypass channel is too dirty, there will be no idle speed, and if the turntable shaft is too dirty, the car will not get off when it just starts (idle speed is above 2000).
