What is the fuel consumption of a 1.5t engine idling with car air conditioning on for one hour?
2 Answers
1.5t engine idling with air conditioning on for one hour consumes approximately 1L of fuel. The fuel consumption when using air conditioning is related to multiple factors such as vehicle model, air conditioning power, and external environment. Below is detailed information about car air conditioning: 1. Overview: The car air conditioning system (air-conditioning-device), abbreviated as car AC, is used to regulate and control the temperature, humidity, air cleanliness, and airflow inside the car cabin to the optimal state. 2. Function: It provides a comfortable riding environment for the driver, reducing travel fatigue; it creates favorable working conditions for the driver, ensuring driving safety. The car air conditioning system typically includes refrigeration, heating, and ventilation devices.
Regarding this issue, I've just experimented with my 1.5T car. The engine has low power output at idle, and the operation of the fan and compressor increases engine load, with fuel consumption basically around 1.0 to 1.2 liters per hour. After the air conditioning system is activated, the compressor requires about 2-3 kilowatts of power, equivalent to burning an additional 0.3 liters of fuel. Different engine types may also cause deviations. I tried running the AC for an hour in summer, and the average fuel consumption record showed 1.1 liters. Additionally, prolonged idling can easily lead to carbon buildup, affecting engine lifespan. It's recommended to turn off the engine if waiting for more than 5 minutes while parked, and use a portable power bank for your phone—saving fuel and being eco-friendly. Don't underestimate this small amount of fuel; doing this frequently can add up to significant costs over a month. In short, using the car's instant fuel consumption feature can give you a rough estimate.
