How much fuel does a car consume when idling for one hour without turning off the engine?

Idling a car for one hour without turning off the engine consumes a significant amount of fuel and can damage the engine. Idling refers to a state where the engine is running without any load. When the accelerator pedal is completely released while the engine is running, it enters an idle state. During idle speed adjustment, the RPM should not fluctuate abruptly, as this can cause premature wear on the engine. It is best to have the idle speed adjusted at an automotive repair facility. Below are specific drawbacks of idling: 1. High fuel consumption: Keeping the air conditioning on while idling in place after parking consumes a lot of fuel because the compressor relies on the engine idling, leading to incomplete combustion of gasoline and the formation of carbon deposits. 2. Toxic emissions: Incompletely burned gasoline produces toxic substances such as carbon monoxide. If the car windows and doors remain closed for a long time, these exhaust gases can enter the enclosed cabin and accumulate to levels that may cause carbon monoxide poisoning. Idling with the air conditioning on emits more harmful exhaust gases compared to driving with the air conditioning on. Idle conditions produce relatively higher amounts of harmful gases such as carbon monoxide, hydrocarbons, and nitrogen oxides.
