What is the fuel consumption when idling with air conditioning on in summer?
2 Answers
In summer, the fuel consumption when idling with air conditioning on ranges between 1L to 3L per hour. Below is more relevant information: 1. Air Conditioning Compressor: The air conditioning compressor is directly driven by the engine crankshaft, with power transmitted between the compressor pulley and the compressor drive shaft via an electromagnetic clutch. When the A/C switch is pressed and the interior temperature is higher than the set temperature, the electromagnetic clutch engages, and the compressor starts working. When the interior temperature is lower than the set temperature, the clutch disengages, and the compressor stops working. 2. Hazards of Long-Term Idling with Air Conditioning On in Summer: (1) Increased fuel consumption, leading to waste. (2) Idling combustion in the engine produces carbon deposits, which over time can cause significant damage to the engine.
I often idle with the AC on in summer while waiting for friends or running errands, which actually consumes quite a bit of fuel. A regular sedan can burn 1 to 1.5 liters per hour – my compact car uses about 1 liter, while larger SUVs may consume even more depending on the model and AC settings. Higher temperatures make the AC work harder, increasing fuel consumption. This isn't just about wasting money – prolonged idling also leads to carbon buildup that damages the engine. I recommend limiting idling to short durations (under 5 minutes) and cracking windows slightly for ventilation to save fuel. Extended idling also increases emissions, harming the environment. Make it a habit to regularly check your AC system to prevent aging components from adding unnecessary strain.
