Orchard Ex said:I was surprised that some of the systems will spray fuel onto the filter to raise the temperature and burn off the ash. Exhaust was getting to 1000 deg F. during a "active regeneration"
Yeah, kind of a weird trade off I guess. Neat idea though, It hit me as a "wow, what cool technology", at first. Then more like "wow, another thing to break", then "wow, how much will the exhaust cooler add to that whole system on top of everything else?"Jeff D. said:I read that also, but from a different article. It sounded like the problem with plugging was compounded without the added fuel to burn the ash, when the diesel was idled for extended periods, ie. OTR trucks with sleepers.
The engine fuel efficiencies dropped after the 03 changes, and may drop again after these changes, despite them having increasingly cleaner exhaust.
Some progress, huh?!?!
"Thank you, Come again!" Yep that's what I meant.Jeff D. said:Orchard, is an APU an "aux. power unit"?? (Either that, or it's the guy selling Squishy's at the Quickie Mart on "The Simpsons" ):bouncegri
I'd like to try running some bio-D just to say I've done it, but there's none available around here.Jeff D. said:I haven't heard anything about the effects of Bio-diesel on the new systems. It'll be interesting too see how it does effect them.I know it's very solvent compared to dino-diesel.

Jeff D. said:I just read an article about the newest Detroit series 60. It stated that it will actively regenerate(remove soot) every 200-400 miles. It goes on to say that this is accomplished by dumping approx. 1 gallon of atomized diesel into the exhaust about 6-8 ft upstream of the cannister (particulate filter). It will be activated by a sensor which reads exhaust system backpressure.
Dumping even more fuel must be good for reducing emissions and economy Theres got to be a better way to clean it without wasting a gallon of fuel every 2-400 miles.Jeff D. said:I just read an article about the newest Detroit series 60.

John DiMartino said:Ive been thinking about this,and it would be easy to shut down the engine in the middle of this process.I mean ,how would it know when is a good time to start it?

Educate me further...
How much gross revenue will the truck earn in those 100K miles, and what precentage of that is $1,547 ?
