Throttle is a controllable valve, which controls air to enter the engine. 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.

There are two kinds of throttle valves: traditional cable throttle valve and electronic throttle valve. The traditional engine throttle control mechanism works through a pull wire (soft steel wire) or a pull rod, one end of the pull wire is connected with an accelerator pedal, and the other end of the pull rod is connected with an accelerator linkage plate. The electronic throttle mainly uses the throttle position sensor to control the opening angle of the throttle according to the energy required by the engine, so as to adjust the intake air.

When cleaning the throttle, it is not necessary to disassemble it, but it is necessary to clean the sealing part of the air inlet, and the idle motor must be disassembled before cleaning. Cleaning the nozzle and avoiding disassembly have their own advantages and disadvantages. Generally speaking, the maintenance station suggests avoiding disassembly and cleaning to prevent unnecessary waste, such as replacing the sealing ring or installing some gaskets after disassembly, or leaking oil during disassembly and assembly. This will delay the master's time.
