Sandka has no warm air when idling.

The reason why there is no warm air when the car is idling is that the engine water temperature is too low, which leads to the low temperature of the warm air system.

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. Simply put, idling means that the engine is "not working".

Idle speed phenomenon, that is, the car is parked while the engine is "chugging"-it is really a waste to burn engine oil for nothing. At this time, the mechanical work generated by gasoline combustion is consumed by the friction of internal parts.
