What do you mean by idling the engine?

Nowadays, many families buy cars. For a car owner, it is necessary to know about the car, so as not to bring more trouble. So what does the engine idle mean?

Engine idle speed refers to the engine speed value when the engine works stably without stepping on the accelerator after starting; The idle speed of the same car is different between cold car and hot car.

Generally, the engine speed is between11500 when the vehicle is cold, and between 700 ~100 when the vehicle is hot.

If the engine speed is higher than the normal value or lower than the normal value, it may be that a function of the engine has failed, and the owner needs to drive the vehicle to the garage in time to avoid damaging other parts of the vehicle.

Abnormal fuel system: If the fuel injector is blocked or the fuel pressure regulator has a fault light, this will lead to abnormal fuel injection, resulting in too thin or too rich mixture, which will lead to unstable idle speed of the vehicle.

Abnormal ignition system: If the spark plug gap is abnormal, or the spark plug electrode is damaged, the energy of the ignition spark will be reduced, or there will be a fire, which will cause the vehicle to rise and fall when idling.

Excessive carbon deposition in throttle: If the carbon deposition in the airway below the throttle is too large, it will lead to abnormal cross section of the airway, which will lead to the control unit not being able to accurately control the intake air at idle speed, and it will also cause the mixture to be too thin or too rich, which will make the vehicle unstable at idle speed.
