How much fuel does a 1.6L car consume when idling for an hour?

[SanAdam]

Currently in the market, most family sedans have displacements of 1.5 or 1.6 liters. When idling for one hour, the fuel consumption is approximately 2 liters per hour. Relevant information about idling is as follows: 1. Introduction: Idling is an operating 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 opening size. Idling means the engine is "producing power without doing work." 2. Driving idle: When the car is in gear without pressing the accelerator pedal or when releasing the accelerator pedal while driving, maintaining the minimum throttle opening, the engine speed matches the parking idle speed. This state is called driving idle.
