What is the fuel consumption when idling with the air conditioning on?

[DeSamantha]

1.6L displacement idling with the air conditioning on for one hour consumes approximately 1.4-2.5 liters of fuel. The following are the specific drawbacks of idling with the air conditioning on: 1. High fuel consumption: Keeping the engine idling with the air conditioning on after parking consumes a lot of fuel because the compressor relies on the engine idling to operate, which can lead to incomplete fuel combustion and the formation of carbon deposits. 2. Toxic emissions: Incompletely burned fuel produces toxic substances such as carbon monoxide. If the car windows and doors are kept closed for a long time, these exhaust gases can enter the sealed cabin. When they accumulate to a certain level, they can cause carbon monoxide poisoning. Idling with the air conditioning on emits more harmful exhaust gases than driving with the air conditioning on. The idling condition produces relatively higher amounts of harmful gases such as carbon monoxide, hydrocarbons, and nitrogen oxides.
