How much diesel does a 430 horsepower engine consume at idle for one hour?
1 Answers
430 horsepower engine consumes approximately 1.5 to 2 liters of diesel per hour at idle. Here are the relevant details: 1. Idle speed is related to engine displacement: Generally, gasoline engines idle at around 800 RPM, while diesel engines idle at around 500 RPM. The higher the engine displacement, the more fuel is consumed per hour at idle. Therefore, when waiting for a long time, it is better to turn off the engine rather than let it idle for extended periods. 2. Hazards of idling: Prolonged idling not only increases fuel consumption but also leads to incomplete combustion of fuel, causing carbon buildup. 3. Auto start-stop function: For owners who are concerned about fuel consumption, they can choose vehicles equipped with an auto start-stop function, which is now available on many cars. 4. Role of auto start-stop: At traffic lights, the vehicle can automatically shut off to save fuel, although during this process, the air conditioning system stops cooling and only blows air. To restart the engine, simply tap the accelerator, and the engine will automatically ignite. In stop-and-go city traffic, the auto start-stop function can save a significant amount of fuel.
