Kayteg1, years ago all diesel engines smoked because the fuel was not refined like the #2 diesel is now days. Also if you had a bad injector they would smoke black really bad. But now with the ULSD you never see a diesel engine smoke whether it is Cat or Cummins or even Volvo or DD.
Engine technology has really improved because of the emission laws imposed, but it has taken some time because at first it was doing more damage to the engine then good.
You are right about the improvements, but still those older CAT have been heavy smokers.
The 3208 CAT were 1980's generation. Later on I bought coach with 1972 Detroit engine and older, 2-cycle diesel smoked much less than those CATs.
Maybe that is why CAT could not continue with on-road engines?
