What is the principle of the throttle valve?
1 Answers
The throttle valve is used to regulate the engine speed. The larger the throttle opening, the lower the speed. There is an air intake hole next to it. When the throttle angle is large, the air pressure inside the engine is less than that outside, and part of the air enters through the small hole on the side, carrying away the corresponding gasoline. In other words, the smaller the throttle opening, the more gasoline is carried away. The throttle valve is a controllable valve that controls the air entering the engine. After the gas enters the intake pipe, it mixes with gasoline to form a combustible mixture, which then burns to perform work. It is connected to the air filter at the top and the engine block at the bottom, and is known as the throat of the car engine. There are two types of throttle valves: the traditional cable type and the electronic throttle. The throttle control mechanism of a traditional engine operates through a cable (soft steel wire) or a rod, with one end connected to the accelerator pedal and the other end connected to the throttle linkage plate. The electronic throttle mainly uses the throttle position sensor to control the opening angle of the throttle according to the energy required by the engine, thereby adjusting the amount of air intake.
