The throttle valve of a car is a controllable valve that controls the air intake into the engine, akin to the "throat" of the car. It is connected to the air filter above and the engine cylinder block below. By regulating the intake air volume, it mixes with gasoline to form a combustible mixture, thereby participating in combustion and power generation.

There are two main types of throttle valves: traditional cable-operated and electronic throttle valves. The traditional cable-operated throttle valve is connected to the accelerator pedal via a cable or rod, while the electronic throttle valve controls the throttle angle based on the engine's required energy through a position sensor.
The cleanliness of the throttle valve is crucial for the normal operation of a car, as it directly affects the car's idle stability, acceleration flexibility, and fuel consumption. If the throttle valve is not cleaned for a long time, it may lead to issues such as unstable idle speed, sluggish acceleration, increased fuel consumption, and in severe cases, even affect the car's startup.
Therefore, it is recommended that car owners regularly inspect and clean the throttle valve to ensure the normal operation of the vehicle. When cleaning the throttle valve, professional cleaning agents and tools should be used, and correct cleaning steps and precautions should be followed. If necessary, one can visit a professional car repair shop for cleaning and maintenance.
