Should the throttle of the family car be cleaned100000 km?

It is suggested that cleaning can improve fuel efficiency and automobile performance.

At present, the fuel injector for automobile is actually a simple solenoid valve. When the electromagnetic coil is energized, the suction force is generated, the needle valve is sucked up, the nozzle hole is opened, 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, forming mist, which is beneficial to full combustion. In the past, the nozzle used in diesel engine was controlled mechanically, and the nozzle of mechanical diesel engine worked by controlling the precision coupling (needle valve and needle valve body). Nozzle coupling is one of the three precision coupling parts of traditional diesel engine, which are plunger, plunger sleeve, needle valve, needle valve body, oil outlet valve and oil outlet valve seat. The nozzle of gasoline engine is a part of the electronic control system of gasoline engine, which replaces the carburetor of carburetor gasoline engine.

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, 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.
