Does idling with the air conditioning on in summer damage the car?

[DeCharlie]

Idling with the air conditioning on in summer does not harm the car in the short term, but it consumes gasoline and causes carbon buildup. Prolonged idling can easily damage the engine, and it is dangerous as it may lead to suffocation. Relevant information is as follows: 1. When the engine is running: If the gasoline in the cylinders does not burn completely, it produces high concentrations of carbon monoxide. 2. While the car is moving: Since air flows through the air conditioning system, creating convection, the concentration of carbon monoxide inside the car remains low. 3. When the car is stationary but the air conditioning continues to run: If the doors and windows are closed, the air inside the car cannot circulate. If carbon monoxide from the engine leaks into the car, it will gradually accumulate, increasing its concentration, which can lead to poisoning or even suffocation. Therefore, avoid running the air conditioning after parking in poorly ventilated areas to prevent carbon monoxide buildup and oxygen deprivation poisoning.
