How Much Fuel is Consumed at Idle?

[SanManuel]

When the engine is running in an idle state, the fuel consumption is related to the engine's displacement. Taking a 1.6L displacement engine as an example, with an idle speed of 800 RPM and no additional loads such as air conditioning or radio, if it runs for 1 hour, the fuel consumption is approximately 1011.2 milliliters, which is slightly more than 1 liter. Relevant information about idling is as follows: 1. Introduction: Idling is a working condition of a car, referring to the engine running in neutral gear. The engine speed during idling is called the idle speed. The idle speed can be adjusted by modifying the throttle size, among other methods. Idling means the engine is "exerting force without doing work." 2. Driving Idle When the car is in gear, without pressing the accelerator pedal or releasing the accelerator pedal while driving, maintaining the minimum throttle opening, the engine speed at this time is the same as the parking idle speed, which is called driving idle.
