idle speed
Stationary engine pace
Idle speed is the rotational speed of an engine when it's running but not doing work—when the vehicle is stationary or the machinery isn't engaged.
Mechanics adjust idle speed to keep engines running smoothly without stalling: The idle speed was set too low, and the car kept dying at stoplights.
