I AGREE UNDER A STOICHIOMETRIC FUEL MIXTURE NO SMOKE IN A DIESEL CAN BE ACHIEVED, (THE BIG HOWEVER) DIESEL FUEL IS PRIMARYALY REFINED OIL AND IS CUMBUSTED UNDER HIGH COMPRESION. AS DIFFERERENCS IN ALTITUDE CHANGE, COMPRESSION LOWERS DUE TO WEAR, FUEL INJECTION PUMPS USUALLY BECOME RICHER WITH TIME ETC,ETC, IT BECOME INCREALINGLY DIFFICULT FOR A MOTOR TO BURN ALL OF THE OIL IN DEISEL FUEL. THIS RESULTS IN THAT BLUE TO BLACK SMOKE. OF COARSE IF YOU HAVE REALLY BLACK SMOKE LOOK INTO A TURBO OIL SEAL LEAK WHICH INTRODUCES ENGINE OIL INTO THE EXHAUST SYSTEM,RESULTING IN CLOUDS OF SMOKE!!!!!


RETIRED CATAPILAR,DIETZ DIESEL MECH.
