Is it okay to leave the air conditioning on all night in a new energy vehicle?

It is not recommended to leave the air conditioning on all night in a new energy vehicle, as it may cause damage to the engine. Causes carbon buildup in the engine: Leaving the air conditioning on all night can lead to carbon buildup in the engine because the fuel does not burn completely when the engine is idling. Causes carbon monoxide accumulation in the vehicle: At the same time, since the vehicle is not moving, it will produce a large amount of carbon monoxide. The generated carbon monoxide gradually accumulates around the bottom of the vehicle, increasing in concentration. Eventually, a certain amount will enter the vehicle through the air circulation system. Carbon monoxide is highly toxic, and even a small amount can be fatal. Therefore, even if you are outdoors and using the internal air circulation (in fact, even with the internal circulation on all night, some air exchange with the outside will still occur), the risk of poisoning is very high.
