What does "idle speed" mean?

The idle speed of a car refers to a working state, and the idle speed of the engine is called idle speed, that is, the gear of the car is neutral, and the speed of the engine at idle speed is called idle speed, which can be adjusted by adjusting the size of the throttle, and idle speed means that the engine does not work hard.

Classification of idle speed

Automobile idle speed can be divided into three categories: normal idle speed, driving idle speed and unstable idle speed. Normal idle speed refers to starting the engine when the vehicle is parked, and the lowest speed of the engine is called parking idle speed (generally, normal idle speed is used to warm up the vehicle and make the engine reach the normal working temperature).

Driving idle speed refers to the state that the minimum opening of the accelerator is kept while driving, and the engine speed is consistent with the parking idle speed without stepping on the accelerator pedal or releasing the accelerator pedal. Idle instability is the most common fault in engine maintenance. If the diagnosis is wrong, the maintenance time will be prolonged and the work efficiency will be reduced.

Use of idle speed

Generally, when you buy a car, you will deal with idle speed every day, because the most commonly used idle speed is normal idle speed, that is, parking idle speed, which is one of the biggest uses of idle speed. It is the most obvious and commonly used use in winter to make the automobile engine reach a suitable working temperature by idling, and it should be noted that the idling speed of a well-working engine is generally 550-800 rpm.

If you know what idle speed means, can you further use idle speed? Especially in winter in the north, if you want to drive a car normally in the early hours of the morning, you must let the engine reach a reasonable working temperature through normal idling, otherwise it is very likely that the engine will stall because it does not reach a suitable temperature during driving, which will lead to safety hazards.
