How Much More Fuel Does Using Air Conditioning Consume?

[LeDaisy]

Vehicle air conditioning consumes approximately 20% of the engine's power, so using the AC will inevitably increase fuel consumption. Typically, it consumes about 1-2 liters of fuel per hour. This may vary slightly depending on the vehicle model and driving speed. Here are some specific tips: 1. Start with external circulation: When entering the car, first turn on the external circulation mode of the AC, then open the doors or windows for ventilation. Once the cabin temperature has dropped, switch to internal circulation mode. This method avoids placing any additional load on the engine while idling, effectively lowering the cabin temperature and reducing fuel consumption. Additionally, adjust the AC vents to face upward, as cold air tends to sink. This helps cool the cabin more efficiently as the cold air descends. 2. Turn off in advance: Another way to save fuel is to turn off the AC about 1.5 kilometers before reaching your destination and switch to external circulation mode. This utilizes the remaining cool air and natural airflow to maintain a comfortable temperature in the cabin, further reducing fuel consumption.
