Does Car Air Conditioning Consume a Lot of Fuel?

[Reese]

Car air conditioning accounts for about 20% of the engine's power, so using the air conditioning consumes a portion of the engine's power, leading to an increase in fuel consumption. The specific increase in fuel consumption is related to the car's displacement and speed. Here is more information about the fuel consumption of car air conditioning: 1. After turning on the air conditioning, the vehicle's fuel consumption will significantly increase, mainly due to the operation of the compressor. The compressor has a relatively high power, which increases the engine's load, naturally leading to higher fuel consumption. 2. The higher the temperature and humidity, the greater the fuel consumption caused by the car air conditioning. When the temperature exceeds 20 degrees Celsius, the increase in fuel consumption varies between approximately 10% and 20% depending on the temperature and humidity. If the temperature reaches extreme levels around 40 degrees Celsius, combined with extreme humidity, the fuel consumption can increase by up to about 30%.
