What's the use of the throttle of a car? Is this important?

The throttle of automobile is a device to control the fuel supply of internal combustion engine. It has a great effect. Without the accelerator, the car can't run normally.

Key points: tread lightly and lift slowly, accelerate in a straight line, use soft force, not too fast, use hard on your toes, and don't shake suddenly.

The accelerator pedal only controls the accelerator, and the current EFI engine only controls the intake. ?

The accelerator pedal of gasoline engine controls the opening and closing angle of engine throttle through linkage mechanism, thus affecting the amount of mixed steam inhaled by the engine, changing the output power of the engine and adjusting the driving speed of the automobile. Of course, when the steam intake is small, the engine speed is low and the number of piston reciprocating is less. ?

The accelerator pedal of a diesel engine car controls the tension of the speed regulating spring of the automatic governor of the diesel engine through the linkage mechanism, and changes the high-pressure oil pump controlled by the governor to supply oil to the nozzle for injecting fuel into the cylinder, thus changing the power and speed of the engine on the surface.
