EOC(Engine off coasting) Duration
 

Does anyone that EOCs (Engine off coasting) have an accurate time count of time spent engine off and moving. If it takes you 10 hours to go through a tank of gas how much of that time is EOC? Also what is your idle fuel burn rate?

Good question
 

Good Question...

Fuel burn is:

0.3 at warm idle stationary, minimal load
0.4-0.6 at warm idle coasting, minimal load
0.5-0.8 at warm idle coasting, high electrical demand

Time spent. Hard to estimate. Mostly stopped anymore, but my 40+ tank last year was 2-5% EO (time) maybe :confused: Now it's more like 1% of time.

Uhh, well. I don't have any way of recording that, but it could be done:
An engine hour timer is easy to be had, not expensive, and hooking them up isn't hard either - wire one up to the ACC position, so it's on whether the engine is or not, and the other to the IGN ON position, so it's recording only while the engine is running. Compute the difference, voila: done.

There's other ways to do it, that's the first one that popped into my head.

If I had to guess, I'd say as much as 10% of my commute can be done Engine Off. I track how many miles I cover gliding, it tends to be about 10% of the total distance.

Really hard to calculate this. I'd estimate my EOC time commuting is approaching 50%, though.

.3 gph at idle, sometimes .2 warmed up in the summer.

Mine is around 25% EOC...my idle is .2gph

You just go off the odometer? What do you do with short glides? interesting idea though.

Welcome to the site. What kind of car are you driving? If you get a chance why don't you make a garage entry for it.

Last tank (recorded here) was aprox 20 minutes EOC. Don't know how many hours total driving. Perhaps I can research that on the next tank. Average speed was 40 mph EOC.

Thanks,
20 minutes out of have many hours for the tank?
