Sorry for the odd question but here goes...

Lets say you are stuck in traffice with 1/4 tank of gas in your h22a or f22 equipped accord, how long will the car be able to idle on a 1/4 tank of gas before it stalls out and dies? Any ideas?

 

you could only test this by filling up, sitting at idle for some set amount of time, and refilling taking a note of home much gas could then fit. With a quarter tank on the gas gauge you still have 6-7 gallons, when the light first comes on you still have 4 gallons. 6 gallons at idle, would probably last six hours.

 

For ******* ever. I tried and tried and tried to run my CL out of gas prior to putting in the Walbro fuel pump. Ran it well below "E" then let it idle in the driveway for god knows how long. Hopped in it again went around the block. Let it idle some more revving it in idle. Nothing.

Gave up and dug into removing the fuel tank and it was still partially full. I'd say > 2hours easy.

 

All I know is that I've idled for an extremely long time on less than 1/4th of a tank of gas once icy night in Dallas traffic and never ran outta gas....needle didn't move that much either....it was a 5hr, 11 mile drive

 

id be worried about the car overheating (especially w/h22a or f22 turbo) before the gas cut out

 

Why at idle?

If the fans work and the coolant system is up to par, idling is the easiest scenario for heat (low rpm, no load).

 

because all that heat and little airflow. I dunno, im just paranoid i guess.

 

W3RD TRUE DAT


aaaaactually your right, my car runs hotter when idleing for longer periods of time then under normal driving conditions.

it is true. Ive heard stories of cars where they idled too long with heater turned on and their cars caught on fire. They said that heat is building up inside the engine with very insufficient airflow cooling the engine down. Fans can only do so much.

 

cars can idle for a an indefinate amount of time without any damage as long as the engine is in proper working order.

http://www.cartalk.com answerd this question many times and they always gave the same answer

my dad had a old 80 dodge omni that idled for 9+ hours while he was at work in the parking lot on a 90 degree day and it did not do anything except purr like a kitten it ate about 1/4 tank of fuel.

 

I have been stuck in LA traffic for over 2 hours with less than 1/4 tank of gas on my F22. The first time I was pretty worried, but the needle barely moved and the temperature never went up much more than normal, and it was over 80 degrees out. This was moving about 10-15 miles in 2 hours.

 

you people are talking about idleing with stock cars, brian said overheating with a h22 and or turboh/f motor a turbo accord a stock type hood with no vent sitting at idle for a long period of time is gonna run hotter than it would moving and hotter than it would if it wasnt turbo'ed... whether or not it would "overheat" i dont care to find out but it is something to consider.

 

actually he is just asking about stock H22 and F22's, fuel mileage should be minimal for idle, I am intereseted in knowing the amount of fuel is used per RPM, there should be a ratio per injector given in the Helms wouldn't you think?

about the heat - there is more of a chance of overheating when sitting at idle for a while because you are not pumping fresh air through your radiator at 50 miles per hour nor are you venting all that heat out from under the hood at a high rate

so heat is going to build in the engine and engine bay, thus heating the coolant and radiator causing it to boil and overheat

A turbocharged engine is still in vacuum at idle, so there isn't anymore heat produced by compression. If I know I'll be sitting more than a few minutes, I'll shut the motor off.

 

if you ask me i'll say that a honda accord (i'm talking about my F22B2) can idle with a 1/4 of a tank for about a day, i swear, i was once stuck in a really bad accident at about 100 F for about 7 hours, with the a/c on, sometimes i would rev it to 1300RPM so that the a/c would cool better and i even turn it off for while cuz we were getting tired of the AC and the gauge didn't move that much, maybe 2 mm! i swear these engines does not consume much gas at idle at all, but i wouldn't let a car idle if i have the chance of turning it off, because there is wear, heat build up and i heard many times that leeting a car idling TOO much is not that good, and i believe it, cuz there is not much oil pressure.

Anyway this was a 5 gen stock, no intake, no headers, so i guess that if you have intake ad headers and exhaust it'll be a lil more efficient

 

The longest time I remember letting my car idle recently was for about 75 minutes while I pulled off the road to sleep, and the needle didn't move at all.
