How much does using car air conditioning affect fuel consumption?

[Gertrude]

It differs by 20%. The car air conditioning consumes about 20% of the engine's power, so using it will utilize a portion of the engine's power, leading to increased fuel consumption. The exact increase in fuel consumption depends on the car's displacement and speed. Below are specific details about fuel consumption: 1. Fuel consumption depends on road conditions: Urban driving, short trips, and stop-and-go traffic all lead to increased fuel consumption. 2. Fuel consumption depends on driving habits: Sudden braking, fluctuating speeds, prolonged engine idling, aggressive acceleration, and long-distance driving at high speeds in low gears can all increase fuel consumption. 3. Principle of vehicle fuel consumption: The fuel consumption per 100 kilometers is an indicator of a vehicle. Driving slower than the optimal speed increases fuel consumption per 100 kilometers, while driving faster than this speed has the opposite effect. If the engine speed is maintained within the same safe range, the hourly fuel consumption remains the same regardless of the vehicle's speed.
