What's That Smell
Okay, I know this is probably the oddest question ever asked, but I'm totally serious and really curious. It has to do with the smell of the exhaust (yep, you read it right).
Having a history of owning other diesel powered vehicles and a history of driving charter buses, I have developed a standard on what I think diesel exhaust should smell like. This may sound weird to some (well maybe not to those on this site), but I like the smell of diesel exhaust. However, the exhaust from my truck doesn't smell like what I think it should and what I have come to love. It has more of a pungent sharp smell. Would that be due to the emissions equipment (DPF, CAT, etc)? I'm guessing that since the DPF is designed to remove the soot from the exhaust, it literally changes the smell. Am I right?
