How much fuel is consumed by idling with the air conditioner on for one hour?
1 Answers
Idling with the air conditioner on for one hour consumes approximately 2 liters of fuel. The engine's rotation primarily maintains the operation of the air conditioning compressor, water pump, oil pump, flywheel, etc. If the clutch is engaged during idling (without pressing the clutch pedal), the engine also drives the gears of the transmission input shaft and other components. The fuel consumption when idling with the air conditioner on depends on the vehicle's displacement and engine tuning. Of course, idling for extended periods mainly increases fuel consumption and causes engine carbon buildup, so it is recommended to avoid keeping the car in standby mode for too long. In idle mode, turning on the heating air conditioner does not cause serious harm to the car, but it can affect the occupants. When the engine is idling, incomplete fuel combustion produces carbon monoxide. If the windows are closed, the concentration of carbon monoxide inside the car will gradually increase, potentially leading to carbon monoxide poisoning for the occupants.
