8.3 and 5.9 liter Cummins engines
I have a 2002 diesel pusher with a 8.3 liter does anyone know what emissions are on it? pretty sure it has a catalytic converter, pretty sure there is no diesel particulate filter, and not sure abou...

The catalytic converter section of the exhaust treatment burns up (oxidizes) fuel not burned up in the engine which is why you no longer smell diesel fuel at the tail pipe. Don't think that there was any exhaust treatment of diesel engines in 2002 with the possible exception of EGR to reduce NOx (which is now done by the DEF treatment).
