Now cars have become seabet myan indispensable means of transportation for our daily travel，But many people will simply use it，But don’t understand some in-depth issues。Just like the engine speed when idling，How much is normal??What problems will occur if the speed is too high?Let’s listen to what the veteran driver has to say。

First，Different models have different engines，Idle speed values ​​are different。Generally, the normal idle speed of a car will not exceed 1000 rpm，Basically around 600-900 rpm。

But on cold start，The idle speed will be higher，Because the engine works at low temperatures, it will cause wear，To avoid this situation，At this time, the engine computer will control the system to increase the idle speed，Rapidly reaches the normal operating temperature of the engine。After the water temperature stabilizes，The normal value is when the idle speed drops back。

Idle speed is set at the factory when the vehicle leaves the factory，There won’t be much difference in daily use。

If the car is warmed up，Idle speed is too high or too low，The car may have a problem，For example, the intake pipe is leaking、The injector is damaged, etc.，Need to go to the repair shop to check。If the idle speed is high and low，If the vehicle shakes seriously，seabet appIt is most likely caused by excessive carbon deposits in the car。

Will idling for a long time damage the car??What if the air conditioner is left idle for a long time in summer?

The maintenance master tells everyone，Won’t damage the car，It’s just that the carbon deposits will produce a little more。Because the engine speed is low when idling，Slow air intake speed，Less air entering the cylinder，Resulting in incomplete combustion，The carbon deposits produced will increase。

Conclusion: About when the car is idling，What is the normal engine speed??Generally at 600-900 rpm，Over 1000 rpm，The car may have a glitch，If the idle speed is too high，You need to go to the repair shop to find out the problem。What is your idle speed??Is there any one with more than 1000 rpm?
