The Detroit Diesel from 2009 up lose about 1/3 of the closet,the Volvo engine has 2 exhaust stacks that go through the roof and those coaches loose even more closet space,I think about 60%.

Gary, that must be a very well insulated and vented area. The DPF, during its regeneration cycle, can reach over 800 degrees! Maybe with the DEF injection system they don't regen as often...I have no idea on that.

Dan, I had looked at that, but couldn't tell where the DPF was. It does show a large exhause component, maybe the DPF, horizontally mounted above the engine in an insulating blanket.

Wow, Thanks for the photo Gary. I never would have imagined it was that big!

One benefit to the '07 with the DPF, and then later the 2010 engines with Urea and "selective emissions reduction" is that in both year changes for the engines, LESS E.G.R. was utilized to attain the desired emissions target for soot, and NOx. Less E.G.R. means more/better fuel economy. Customers I've talked to with either of these engines (although more complex and space-robbing) better mileage has been reported versus the 04, 05, and 06 Series 60 engines.
