Yes, similar effect, but there is a limit to how much diesel you can dump in there before 
it stops burning completely and makes so much soot that it clogs up the combustion chamber 
and exhaust valves.  So adding a cleaner burning fuel like propane lets you get closer to 
fully using up the oxygen in the cylinder w/o the adverse affects of soot formation.
