What is the function of a car throttle valve?

1 Answers

The throttle valve has many functions, mainly including the following aspects: 1. Enhancing power through acceleration or deceleration; 2. Correcting the intake function through its self-regulation; 4. Controlling the operation of the engine assembly (the idle switch inside the engine is working); 5. Controlling the flap, through the operation of sensors, to regulate the intake volume for power enhancement. A dirty throttle valve is mostly caused by poor air quality and fuel quality. Carbon deposits generated during gasoline combustion, due to negative pressure, can contaminate the throttle valve, leading to poor closure, increased intake volume, signal transmission errors, excessive fuel consumption, and engine idle vibration. Therefore, during maintenance, it is essential to frequently check the throttle valve opening. If it exceeds the normal range, it should be cleaned.
