Benefits of regulating valve for large trucks

The advantage of adjusting the valve of large trucks is to reserve the expansion coefficient of the valve metal, so as to prevent the valve metal from expanding without expansion gap, resulting in lax valve closure and air leakage.

The throttle of a large truck is equivalent to the breathing system of the engine, similar to our throat. It is the gate that controls air in and out of the engine. When the outside air enters the engine, the gas will mix with gasoline to produce a combustible mixture. The upper end of the throttle valve is connected with the air filter and the lower end is connected with the main body of the automobile engine. After the combustible mixture is produced, it will enter the engine through the delivery pipe, thus triggering the power system of the engine.

The role of the throttle:

1. Control the amount of air absorbed by the engine, and provide enough air for the engine to burn by controlling the amount of air flowing into the engine.

2. Throttle opening represents engine working load. The greater the throttle opening, the greater the engine workload (the greater the torque at the same driving speed, the faster the working speed at the same torque). Throttle basically consists of accelerator pedal, throttle cable, throttle opening sensor and throttle butterfly valve.

Throttle provides ECU signal for engine intake through throttle opening. The opening time of ECU injector transistor is prolonged, the opening time of injector is prolonged, and the fuel injection quantity is increased. The main function of throttle valve is to provide engine load signal to ECU and set a basic fuel injection time, which is the basic function of throttle valve.
