When do the throttle and intake nozzle need cleaning?

When the throttle and intake nozzle need to be cleaned, the throttle should be cleaned every 20,000 kilometers, and the nozzle should be cleaned every two years or 60,000 kilometers. 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. The air filter is connected with it, and the engine block is connected with it. The fuel injector is a simple solenoid valve. The electromagnetic coil is energized to generate suction, the needle valve is sucked up to open the nozzle hole, and the fuel is ejected at high speed through the annular gap between the shaft pin at the head of the needle valve and the nozzle hole, which is beneficial to full combustion and may affect the engine performance.
