How much fuel is consumed by running the heater for one hour while parked?
1 Answers
Running the heater for one hour while the car is parked consumes approximately 0.6-1L of fuel. Under normal circumstances, turning on the heater does not increase the engine's fuel consumption. The heater relies on the heat generated by the engine's cooling system. There is a small fan in the engine compartment that blows the heat collected by the cooling system into the car. The correct way to use the heater is to turn it on when the water temperature gauge reaches the middle position. However, it is recommended to first use the external circulation mode to expel the cold air inside the car, then switch to internal circulation after 3-5 minutes. Idling with the heater on can be harmful to the car. Since the engine is idling, the fuel does not burn completely, producing carbon monoxide. If the windows are not opened, the concentration of carbon monoxide inside the car will gradually increase, potentially leading to carbon monoxide poisoning for the occupants. Additionally, it can increase engine carbon buildup. Generally, the larger the engine displacement, the higher the fuel consumption per 100 kilometers. However, there is no fixed formula to calculate this, as factors like the driver's control cannot be standardized. Engine displacement, curb weight, gross vehicle weight, actual engine operating conditions (RPM, torque output), and road conditions can all be reflected through the engine's real-time parameters.
