Wouldn't doing that in the 6.5s, mess with the optical eye thing in the injector?



If you look under the back of the new duramax's you'll see this funny looking trumpet thingy on the end of the exhaust. GM put that there as a passive exhaust cooler so that if your truck starts to regen in the mall parking lot you won't light some little old lady who happens by on fire.

The "cone" on the exhaust is supposed to pull more air through to keep the heat from burning the paint or other things.Not being able to do a parked regen is the reason a lot of school buses and pick ups are getting brought in on the hook.
They do not get driven long enough at speed or under load to get the DPF hot enough to regen.
The days of driving your diesel rig as a grocery getter is over if you buy a new one.
Volvo and Macks have the ability to initiate a parked regen. Unless it is a tanker or some such rig.
All the Roadway, USF Readyway rigs don't have this option and as they have a lot of in town rigs they are always coming in on the hook.
Woohoo next year they get the piss tanks too.
Urea will be injected also to further reduce emissions. All that will be leaving the tail pipe is water vapor and CO2
Aint progress grand ?
