How to adjust the throttle of Dongfeng Shen Feng a60?

The electronic throttle can adjust the idle speed as follows:

1. Loosen the throttle adjusting screw to make the engine reach the lowest stable speed.

2. Put the screwdriver on the idle screw, and when the engine is about to stall, use the screwdriver to unscrew the idle screw slowly, so that the engine can run smoothly and reach a high speed.

3. Unscrew the throttle screw to reduce the engine speed from high speed to a minimum.

4. Unscrew the screw and increase the engine speed until the throttle opening becomes smaller and the throttle suddenly closes.

The working principle of electronic throttle is as follows:

1. The driver manipulates the accelerator pedal, and the accelerator pedal position sensor generates the corresponding voltage signal and inputs it into the throttle control unit.

2. The control unit calculates the required torque and throttle angle, and sends corresponding voltage signals to the drive circuit module.

3. Drive the control motor to make the throttle valve reach a better opening position.

4. The throttle position sensor feeds back the throttle opening signal to the throttle control unit to form closed-loop position control.
