Problems existing in electronically controlled fuel injection system of automobile engine
Throttle and valve are two different things. The accelerator pedal we step on controls the opening of the accelerator. The so-called increase the throttle is to increase the opening of the throttle. At present, there are two control methods for the throttle used in automobiles. One is that the accelerator pedal directly controls the opening of the accelerator through the zipper, which is a mechanical control mode; The other is that the accelerator pedal is equipped with a position sensor, which sends the signal of the driver stepping on the accelerator to the engine ECU, and the ECU obtains the driver's driving intention through this signal, and gives the control instruction of the accelerator motor after calculation to meet the required torque output. This is an electronic control mode, commonly known as electronic throttle control. Valve refers to the intake valve or exhaust valve of the cylinder, and its opening and closing are controlled by the camshaft.
