Working principle of throttle valve

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. It connects the air filter and the engine block, and is called the throat of the automobile engine.

Whether the acceleration of a car is flexible or not has a lot to do with the dirt of the throttle. Cleaning the throttle can reduce fuel consumption and make the engine flexible and energetic. Whether the throttle should be removed for cleaning is also the focus of discussion among car owners.

Classification of throttle valves:

1, throttle body of mechanical cable

The oil pedal is connected with the throttle body through a steel wire rope. The driver steps on the pedal and finally pulls the flap in the middle of the throttle through the transmission of power. The larger the flap opening, the larger the air intake and the stronger the power output of the engine.

If it is idling, the air does not enter the engine through the flap at this time, because the driver does not put pressure on the throttle, but through the nearby motor.

There is a small hole in front of the flap, which leads to the back of the flap. The engine computer can directly input commands to the motor to start the motor. At this time, air will bypass the throttle and directly deliver air to the engine through the small hole, thus entering the engine for combustion.

2. Electronic throttle body

The interior consists of a motor, which is used to control the opening of the solar panel. This is based on the signal sent by the driver stepping on the oil, which is finally received and judged by the engine computer, and then a voltage of 5V is provided to drive the motor, so the air intake control is more accurate. Pure electronic equipment, very low failure rate,
