Fuel consumption of a 2.0T engine idling with AC on for one hour?

[SiennaDella]

With the air conditioning turned on and idling for 1 hour, a 2.0T engine typically consumes approximately 3-4 liters of fuel. Below is relevant information about car idling: 1. The function of car idling: Idling is an operational state 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, among other methods. Idling means the engine is 'producing power without doing work.' When the engine is running, if the accelerator pedal is completely released, the engine enters the idling state. 2. Causes of unstable idling: Direct causes refer to mechanical components being dirty, worn, or incorrectly installed, leading to changes in cylinder power output, which results in an imbalance of power among cylinders and causes unstable engine idling. Indirect causes refer to abnormalities in the engine's electronic control system, leading to poor combustion of the air-fuel mixture, making it difficult to balance the power among cylinders, and resulting in unstable engine idling.
