How normal is the car idling?

The idle speed of Pacific Auto Network will be different under cold and hot conditions. Generally, the idle speed of an engine with good working performance under hot car conditions is generally 550-800 rpm. When the car is cold, the idle speed of the engine will be relatively high, generally at 950- 1300 rpm. When the engine temperature rises to a certain value, the idle speed will drop to the normal value.

Because the engine needs to enter the normal working environment as soon as possible after the car is started in a cold state, when the car is started, the engine computer will automatically inject more fuel, and by burning more fuel than the normal idle speed, the water temperature of the engine will rise rapidly, so that the engine can quickly enter the appropriate temperature.

Idle speed means that the engine runs with no load, and it only needs to overcome the friction resistance of its internal parts and does not output power to the outside. The lowest speed to maintain the stable operation of the engine is called idle speed, which is one of the five basic working conditions of the engine. Idle speed can be adjusted by adjusting throttle opening and idling oil supply. Generally speaking, the minimum idle speed is the best when the engine does not shake in the idle speed range and the acceleration performance is good.

The idling speed of automobile engine is one of the engine operating conditions, so the idling performance of the engine has a great influence on emissions, fuel consumption and comfort. The idle speed of the engine is called idle speed, which cannot be too high or too low. Too high will increase fuel consumption, too low will make the engine idling unstable.
