Does using P gear with air conditioning on affect the car?
1 Answers
Leaving an automatic transmission car in P gear with the engine running and air conditioning on for a long time does not damage the car. P gear is the most common gear in automatic transmission models, usually located at the frontmost position of the gear shift console, in front of the R gear, designed to lock the axle when the car is stationary on a slope. However, when the vehicle is idling in place, the gasoline in the engine may not burn completely. If this happens frequently over a long period, it can increase the formation of carbon deposits in the engine, and relatively, fuel consumption may also increase. In addition, if you rest in the car with the air conditioning on in a confined environment, a large amount of gas can enter the car through the vehicle's ventilation system. Staying in the car for an extended period under such conditions can easily lead to carbon monoxide poisoning. If the driver must rest in the car, it is advisable to first park the car in an open and ventilated location. Then, lower the window by about two fingers' width for ventilation, and finally switch the air conditioning mode from internal circulation to external circulation to ensure proper air flow inside the car.
