How Much Does Using Air Conditioning Increase Car Fuel Consumption in Summer?

[LaneAnn]

For most family cars, the displacement is generally between 1.3-2.5L, and the fuel consumption is usually 6-10L/100km. After turning on the air conditioning, the fuel consumption typically increases by 10-15% of the original consumption, resulting in an additional 0.6L-1.5L per 100 kilometers. Related details are as follows: 1. Reason: In daily use, when the AC button is pressed, the air conditioning compressor needs to perform cooling work. Since the car's air conditioning compressor is directly driven by the engine, it consumes part of the engine's power, thus increasing fuel consumption. 2. Compressor: If it is a fixed displacement compressor, there is no need to deliberately adjust the temperature and fan speed, because for cars with fixed displacement air conditioning pumps, as long as the air conditioning is on, the fuel consumption is almost fixed, regardless of the temperature setting or fan speed. On the other hand, for variable displacement compressors, fuel consumption is related to the temperature setting.
