rolling coal, excessive soot

Dain Bramage · Oct 30, 2007

what causes it? i have been watching some diesel vids on youtube, and i notice that all of the trucks that are making big power numbers are blowing a lot of smoke. i think someone told me that it is unburned fuel?

Oh crap! I'd better get that looked at! :awesomework: Dainbramage... when you overfuel a diesel, significant power gains are achieved by combusting the easy to burn off hydrogen from the diesel first and leaving the longer burning carbon molocules to roll out the tailpipe. Like this!
