What is "idle speed"?
Idle state refers to a working condition when the engine is idling. When the engine is running, if the accelerator pedal is fully released, the engine is at idle.
The speed at which the engine is idling is called the idling speed, which is the minimum speed at which the engine can run normally when there is no work. Idle speed can be adjusted by adjusting the size of the damper. Generally speaking, the idle speed is the best when the engine is not shaking.
