Default Fuel Consumption while standing still

can anyone here comment abt the fuel consumption of a car while it is standing still running with a/c. the power cuts and the city heat in new delhi force me to just switch on the ac too much.
any comments are welcome.

Well,what I've heard somewhere is for every 10 mins. of idling time ,the car consumes around 100ml of petrol ( 1/10th litre).
I don't know whether it is for with/without AC..it's just that I read these figures somewhere sometime ..can't recall,but I think it was in some auto magazine a 15-18 months back..

switching on the A/c does use up engine revs thereby increasing consumption .. cant really say how much the consumption increase while idling with the a/c on .. so maybe it increases from 100ml /10mins to 110ml/10 mins ...

it leads to engine overheat in more often in smaller cars like altos and 800s ..

The guy who takes care of my cars at the service centre told me sometime back that in about half an hour around 1 litre would be consumed.

I asked him coz I would listen to my stereo with two amps in my parked car for 30-40 mins with the engine running! If I were to listen to my stereo without the engine running for long durations on battery power alone I would have fryed umpteen batteries by now!!

People dying is explained by CO leaking into the car. Odourless, leads to asphyxiation. Could happen if you sit with the AC on for prolonged periods.

thats a lot relief!
0.9 ltrs an hour can be afforeded considering the day's heatwave in delhi.
btw, howz an idle engine consumes more fuel than a running engine with gear-shifts...?
sounds a little odd???

how did you figure that, bro? If you consume 1/10th of a litre every 10 mins, it means 1 litre per 100 mins, or 1hr 40 mins. Thats saying 15km in 1hr 40 mins, if your FE is 15 kmpl. Which is the equivalent of driving at lower than 10kmh for over an hour and a half.

That would show that idling consumes less fuel than running.

I've heard about this, and also people dying accidently when they start a car inside a closed garage(and let it warm up).

But I've always been able to smell the exhaust gas that the car gives.
I'm just curious, since things other than CO come out of the exhaust. And how is it that people don't smell it?
