Is it safe to sleep in a diesel car with the air conditioning on while idling?

No, sleeping in a diesel car with the air conditioning on may lead to poisoning. When the car is idling with the windows closed and the air conditioning running, the system can draw exhaust fumes into the cabin. These fumes contain carbon monoxide and various harmful gases. Excessive inhalation of these gases can cause unconsciousness and brain hypoxia, and in severe cases, can be fatal. Below are some precautions for using car air conditioning: 1. Avoid prolonged single use of the air conditioning: If the interior temperature has reached a comfortable level, turn off the air conditioning or switch it on intermittently. Prolonged use can increase the pressure on the condenser, causing wear and tear on the cooling system. Therefore, it is advisable not to use the air conditioning for too long at a time. 2. Ventilate by opening windows: Upon entering the car, open the windows and turn on the external circulation to expel the hot air. 3. Avoid prolonged use of internal air circulation: Internal circulation recirculates air within the closed cabin, leading to a gradual decrease in oxygen levels. Additionally, if gasoline in the cylinders does not burn completely, carbon monoxide from the engine may leak into the cabin, deteriorating the air quality inside and potentially causing harm to the occupants.
I've personally experienced this issue before, and it almost led to a serious problem. Sleeping in a diesel car with the air conditioning on may seem convenient, but it poses significant risks, especially due to the accumulation of carbon monoxide from the exhaust inside the vehicle. Once, I took a roadside break and slept for half an hour with the AC on. When I woke up, I felt dizzy and groggy, and upon checking, I realized the windows weren't completely sealed, allowing external exhaust to seep in. Fortunately, I noticed it in time, or the consequences could have been dire. When the car is idling, the heat and position of the exhaust pipe can directly draw gases into the cabin. Combined with the reduced bodily response during sleep, this can easily lead to poisoning. Now, I strongly advise against doing this. It's better to find a service area or a safe parking spot, open the windows for ventilation, and then rest. Safety first! Sharing similar stories in life can help prevent tragedies.
