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

[Lawrence]

There is some variation depending on the vehicle model, but for household cars, it is generally between 1L to 3L of fuel per hour. Relevant information about idling is as follows: 1. Introduction one: Idling refers to the operation of the engine without any load, only overcoming the friction resistance of its internal components, without delivering power externally. The minimum speed required to maintain stable engine operation is called idling, which is one of the five basic operating conditions of an engine. 2. Introduction two: When adjusting the idle speed, the RPM should not fluctuate abruptly, as it can cause early wear to the engine. If you rest in the car with the AC on for a long time, especially in recirculation mode, the air quality inside the car will become increasingly polluted, and harmful gases will gradually accumulate, posing health risks and even life-threatening dangers. Please be cautious.
