How many liters of fuel does a 1.6L engine consume per hour at idle?
1 Answers
According to current calculations for vehicles with displacements generally ranging from 1.5 to 1.8 liters, the fuel consumption per hour at idle is approximately 1-2 liters. Here are the relevant details: 1. High idle speed is related to engine displacement: Generally, gasoline vehicles idle at around 800 RPM, while diesel vehicles idle at around 500 RPM. The higher the engine displacement, the more fuel is consumed per hour at idle. Therefore, when waiting for long periods, it is better to turn off the engine rather than letting it idle. 2. Hazards of idling: Prolonged idling not only increases fuel consumption but also leads to incomplete combustion of gasoline, resulting in carbon buildup. 3. Auto start-stop function: For car owners who are particularly concerned about fuel consumption, they can choose vehicles equipped with an auto start-stop function when purchasing a car. Nowadays, many vehicles come with this feature. 4. Role of auto start-stop: At traffic lights, the vehicle can automatically shut off to save fuel. However, during the shutdown, the air conditioning system's cooling function will stop and switch to blowing air. To restart the engine, simply lightly press 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.
