What is the throttle diameter of 1ur?

The throttling diameter of 1ur is φ65.

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 classification:

There are two kinds of throttles: traditional cable throttle and electronic throttle. The traditional engine throttle control mechanism works by pulling a cable (soft steel wire) or a pull rod. One end of the cable is connected with the accelerator pedal, and the other end is connected with the accelerator linkage plate.

The electronic throttle mainly uses the throttle position sensor to control the throttle opening according to the energy required by the engine, so as to adjust the intake air.

Note: When cleaning the throttle, it is not necessary to disassemble it, but the sealing part of the air inlet must be cleaned. Idling motor can only be cleaned after disassembly. Nozzle borrowing and cleaning without disassembly have their own advantages and disadvantages. It is recommended to avoid disassembly in general maintenance stations to prevent other unnecessary waste, such as the need to replace the sealing ring or install some other gaskets after disassembly, or the phenomenon of oil leakage and air leakage during disassembly, which will delay the owner's time.
