How much fuel does a 1.5t car consume when idling with AC on for one hour?

[LeJuliette]

1.5L displacement vehicles consume approximately 2.0 liters of fuel when idling for one hour. Below is relevant information about car idling: 1. The function of car idling: Idling is an operational state of a vehicle where the engine runs in neutral gear. The engine speed during idling is called idle speed, which can be adjusted by modifying the throttle opening. Idling means the engine is "producing power without doing work." When the accelerator pedal is fully released while the engine is running, the engine enters idling state. 2. Causes of unstable idling: Direct causes include dirty, worn, or improperly installed mechanical components leading to variations in cylinder power output, resulting in imbalance among cylinders and causing unstable idling. Indirect causes refer to abnormalities in the engine's electronic control system causing poor combustion mixture, making it difficult to balance cylinder power and resulting in unstable idling.
