How much fuel does a car consume when idling for one hour without turning off the engine?

When a car idles for one hour without turning off the engine, the fuel consumption during idling can be affected by factors such as the vehicle's displacement and whether the air conditioning is on. Taking an ordinary 1.5-liter displacement family car as an example: 1. The normal idling fuel consumption is approximately 1-1.5 liters per hour, while with the air conditioning on, it can reach up to 2.5 liters per hour. Based on an average fuel consumption of 7 liters per 100 kilometers, this is equivalent to the fuel consumption of driving 35 kilometers. 2. The larger the vehicle's displacement, the higher the fuel consumption naturally. Here are some additional points: 1. Prolonged idling can affect the engine: Frequent idling in place may also lead to engine malfunctions. If the vehicle remains idle for an extended period, the fuel will not burn completely. These unburned substances will remain in the engine and, over time, form carbon deposits. Carbon deposits can cause various issues in the engine, such as engine shaking, noise, high fuel consumption, poor acceleration, and difficulty starting. 2. Incomplete fuel combustion can also release a large amount of carbon monoxide: Since the vehicle is stationary, these harmful gases can enter the car through the air conditioning system, posing health risks to passengers inside. Prolonged exposure can also harm the vehicle itself and lead to oxygen deprivation in the car.
