Idling with air conditioner on
mysticolor
idling and running the air conditioner? I have a Dodge minivan with a 3.3
liter engine.
How's the wear and tear?
I checked the archives, and it was pretty empty.
Any other ideas for keeping the van cool while sleeping in it during the
summer?
Thanks

My car takes 0.5 litres / hour when idling, with a/c 0.2 litres more.
But it is a station wagon with a small diesel engine.

Sounds like at least 1 ... 1.5 litres idling and perhaps up to 0.5 litres
for a/c.

The german automobil-club "ADAC" makes a lot of tests.
I have my numbers from them.

Where was the exhaust? If it's on the back side and the fresh air is
coming from the front, with ventilators on and therefore slightly more
pressure inside the car, what's the problem?

It is not a good idea to sleep in a car that is not moving with the
engine running. Carbon monoxide could get in the cabin and it could end
up being your last nap.

Relatively little fuel, but I wouldn't hazard a guess as to how many
gallons per hour.

Horrible. Gasoline engines hate to idle, especially with a load like the
A/C. Diesels don't mind at all because they're still moving a lot of air
at idle through the engine (no throttle), but gasoline engines move very
little air and therefore the combustion dynamics are very bad (not
enough turbulence for a complete burn, plus a small fuel/air charge
trying to burn in relatively large cylinders. Oil pressure is low and
less oil gets squirted onto the cylinder walls, and the valve train gets
less oil and cooling.

GADS!!! You wouldn't SERIOUSLY sleep in a van with the engine running,
would you? Thats a good way to get carbon monoxide poisoning (catalytic
convertors don't work very well during extended idling, either).
If it were a camper/van, I'd say install an electric A/C and run it from
a portable generator set up AWAY from the van. No other real ideas.

Not in the concentrations normally found in modern vehicle exhausts,
but the common sense principle remains valid nonetheless.
The last Air Care test for my '89 showed the CO concentration to be
0.02% from a warm engine: enough to do some harm, maybe, but not a
lethal dose. LD50 is something like 0.08% for about two to three
hours, or 1.28% for about three or four minutes.
Exhaust gases entering the cabin still can't be too healthy
though...

I'm guessing those lethal concentrations are in air, not car exhaust.
Think "Oxygen Displacement".

Not in current-production vehicles. They just don't produce that much CO
anymore. Certainly it wouldn't happen if you were snoozing in the vehicle
when it's parked outside somewhere.

Don't bet on that, at least not with your life. Catalysts don't work as
well during extended idle as they do during cruise or brief periods of
idle after cruise. I'd be willing to bet if you monitored CO
concentration in exhaust, it would increase steadily the longer you
allowed the engine to idle.
