Does Dongfeng Scenery 580 need an accelerator pedal?

No need. Replacing the electronic accelerator pedal does not require re-matching. The electronic throttle controls the opening of the throttle through cables or wire harnesses. On the surface, the traditional throttle cable is replaced by a cable, but in essence, it is not only a simple change in connection mode, but an automatic control function for the power output of the whole vehicle.

Principle of automobile accelerator pedal;

1, the throttle of gasoline engine does not control the fuel injection quantity, but controls the throttle opening. That is, if the opening is small and the mixture entering the steam cylinder is small, the power generated by the engine will be small, and vice versa;

2. The more mixed gas enters the steam cylinder, the greater the force generated by combustion, so the greater the force to push the piston and the faster the piston moves, thus making the engine rotate faster;

3. For gasoline engines, the throttle valve controls the opening of the throttle valve, thus affecting the intake of the engine. After stepping on the accelerator, fresh air increases, and the fuel injection quantity controlled by ECU also increases, so the force generated by combustion also increases, driving the engine to run faster.

4. For diesel engines, the throttle valve directly controls fuel injection. With the increase of fuel, the force generated by combustion also increases, thus driving the engine to run faster.
