ENFORCEMENT OF DIESEL SMOKE EMISSIONS FOR THE STATE OF NEW JERSEY

THE RESEARCH PROGRAM UNDERTAKEN BY NEW JERSEY TO DETERMINE TESTS AND INSTRUMENTS WHICH CAN BE USED BY AUTHORIZED STATE AGENCIES FOR THE ENFORCEMENT OF DIESEL SMOKE EMISSIONS IS REPORTED. THE STATE AGENCIES UNDER CONSIDERATION FOR THE ENFORCEMENT OF DIESEL SMOKE EMISSIONS ARE THE DIVISION OF MOTOR VEHICLES, THE PUBLIC UTILITIES COMMISSION, AND THE NEW JERSEY STATE POLICE. THE MAXIMUM INSPECTION TIME FOR EACH VEHICLE WAS NOT TO EXCEED ONE MINUTE. EIGHT DIFFERENT TESTS WERE EVALUATED TO DETERMINE WHICH ONES CORRELATED WELL WITH NORMAL VEHICLE OPERATION. THESE TESTS INCLUDED ACCELERATION OF A FIXED EXTERNAL INERTIA, FREE ACCELERATION OF ONLY THE MOVING PARTS OF THE ENGINE, THREE RAMP TESTS, A TEST IN WHICH A HEAVY VEHICLE WAS TOWED, AND A DRIVING TEST IN WHICH THE VEHICLE BEING TESTED WAS ACTUALLY ACCELERATED. THE RESULTS OF TESTS DEMONSTRATED THAT THE MODIFIED FREE ACCELERATION METHOD CORRELATES REASONABLY WELL WITH A LOADED STEADY STATE CYCLE, DISTINGUISHES THE HIGH EMITTERS AND IS SIMPLE TO PERFORM. CONSEQUENTLY THE FREE ACCELERATION TEST METHOD IS RECOMMENDED FOR USE IN INSPECTION STATIONS AND ON THE ROAD. /AUTHOR/
