What is throttling?

The accelerator pedal, commonly known as the accelerator, is a control component for the driver to control the throttle opening of the carburetor according to the working conditions and adjust the intake air of the mixed gas in the cylinder, so as to change the engine speed and adapt it to the working conditions.

The accelerator pedal of diesel vehicle is used to control the effective stroke of the plunger of the fuel injection pump, adjust the amount of oil injected into the combustion chamber, and make the engine speed change as needed.

When operating the accelerator pedal, the right heel and hand should be placed on the cab floor as the fulcrum, and the sole of the foot should be lightly pedaled. When stepping on it, the fuel supply increases and the engine speed accelerates; It's just the opposite when you relax. When operating the pedal, you should pay attention to the softness, so as to "step on it gently and lift it slowly", and you must not step on it continuously.

In addition to the accelerator pedal, the parts that control the carburetor accelerator, as well as the accelerator knob (commonly known as hand accelerator), are all auxiliary devices of the accelerator pedal, which fix the carburetor accelerator at any opening.
