When does the accelerator of the car start?

When the car starts, the car is at idle speed. At present, there are two kinds of engine idle speed control. One is the throttling bypass type. When this type of engine does not step on the accelerator pedal, the accelerator is closed. When the car starts idling, air enters the cylinder through the bypass channel, and the idling control valve controls the intake to control the idling of the engine. The other is the throttle control air intake type. In order to keep the engine idling, the throttle will have a certain opening, which is also the minimum opening value of the throttle. This system is an intelligent electronic throttle control system. The idle speed will be controlled by the idle motor, which will be instructed by the driving computer according to the speed sensor, water temperature sensor, crankshaft sensor and throttle sensor. I hope it can help you.
