During a test run of a propane injected N14 Pete, talked to a Cummins guy in Columbus OH said in 2010 there will be a tank mounted under the trucks injecting what he called skunkpiss (ethanol) into the dpf... we'll see.

That would be a lot smarter than the system that they installed on our 6.7s. Instead of a 50% increase in fuel, injecting urea would be a much better answer for gaining back some fuel economy and still running a clean exhaust.

One of the big reason for the change is due to bio diesel. Bio diesel has a issue of not vaporizing with post injection, adhering to the cylinder wall and diluting the oil. This was quoted by Cummins in a Biodiesel Magazine. Thats why over the road trucking, from what I was told, stayed away from post injection when implementing the regen system.

I could see problems from owner's letting the skunkpiss tank run dry. No regen, clogged dpf. I kind of like the idea of regen independent of motor operation, even if it used the diesel fuel with a separate low pressure injection from the lift pump. They would have to include a system to warn the operator and eventually prevent the truck from starting if they depended on a separate ethanol tank to deal with the possibility of the tank running dry.

They will probably set up a limp mode deal for a dry urea tank, I think that is how the Benz urea implementation works. From what I've read on those the urea is a dealer only serviceable thing so until we can buy it (or make it) ourselves we end up chained to the dealer and who knows how much that will cost.

needs to be service about every 1-2 oil changes. so that $100 oil change goes to $300. Fun

Seems like this is unnecessary for the 6.7L Cummins as it's already 2010 Emissions compliant in it's current incarnation.

Some think that it might work about better than the current post fuel injection cycle / 'take your truck out for a run' to clean it out deal, should benefit the folks who short trip a lot but with urea not being commonly available it might just move what fuel cost savings are had to dealership expenses.

...not once you get done "fixing" it so it will get some decent fuel economy.

Are these people even thinking when they come up with these devices? I mean for crying out loud, don't these trucks already cost enough and now we are going to have to go back to the dealership every 1-2 oil changes to have a stupid tank refilled? God this country has lost it's freaking mind.

They have put men on the moon and rovers on mars (with off-the-shelf RadioShack parts, no less), but they still can't keep the fourth wheel on the shopping cart from wildly wobbling.

I can only have nightmares about their next solution for diesel exhaust treatment to appease the Nature Nazis.

Assuming it is the liquid form, could you not buy the pellet form and dissolve it yourself ? You can get a 50# bag at CoOp for less than 10 bucks. Once you knew the ratio of course.
