Idling the car with the AC on in summer does affect the vehicle. This is because prolonged engine idling with the AC running can easily increase fuel consumption. Below is relevant information about car idling: 1. Function: Idling overcomes the engine's own operational resistance, maintains the minimum engine speed, and provides a convenient device for drivers to drive under various circumstances and make temporary stops. 2. Definition: When the engine is running without load, it is called idling. When the engine is running and the accelerator pedal is completely released, the engine is in an idling state. The engine speed during idling is called the idle speed. The idle speed can be adjusted by changing the throttle opening size. Generally speaking, the optimal idle speed is the lowest speed at which the engine does not vibrate.
