What is the normal idle speed for driving?

[VonMariana]

Car idle speed is generally 700-800 rpm. The specific introduction about idle speed is as follows: 1. Meaning: The idle speed of a car refers to a working condition. When the engine is idling, it is called idle speed, which means the car is in neutral gear. The engine speed at idle is called idle speed. The idle speed can be adjusted by changing the throttle size. Idle speed means the engine is 'working without output'. 2. Normal idle speed: When the vehicle is in a parked state and the engine is started, the minimum speed at which the engine runs stably is called parking idle speed (the process of the engine changing from a cold idle state to an idle state where the engine reaches normal operating temperature is called warm-up or hot start).
