How much fuel does a car consume in one hour of idling?
1 Answers
A car consumes approximately 2L of gasoline during one hour of idling. During idling, the intake pressure is low and the airflow is weak, requiring the engine to inject more fuel to maintain a higher air-fuel mixture concentration to keep the engine running, which also increases fuel consumption. Reasons for increased idling fuel consumption: The reason idling leads to higher fuel consumption is that the engine is operating in an abnormal state. During idling, the engine speed is very low, the intake swirl weakens, and fuel atomization is poor, resulting in incomplete combustion. The prolonged fuel burning time and increased cylinder heat dissipation losses also contribute to higher engine fuel consumption. For naturally aspirated engines, the low intake pressure and weak airflow during idling necessitate the engine to inject more fuel to maintain a higher air-fuel mixture concentration for operation, further increasing fuel consumption. Idling performance: When the engine is running and the accelerator pedal is completely released, the engine enters an idling state. When adjusting the idle speed, the RPM should not fluctuate abruptly, as this can cause premature wear to the engine. It is best to have the idle speed adjusted at an automotive repair facility. The idle speed can be adjusted by modifying the throttle opening and idle fuel supply. Generally, the optimal idle speed is the lowest RPM at which the engine does not shake within the idling range and maintains good acceleration performance.
