U.S. COAST GUARD POLLUTION ABATEMENT PROGRAM: A PRELIMINARY REPORT ON THE EMISSIONS TESTING OF BOAT DIESEL ENGINES

The exhaust emission concentrations from three GM6-71's and a Cummins VT-350 diesel engines were measured on a dynamometer as a function of engine load. The GM6-71 engines were newly rebuilt by the Coast Guard; the Cummins Engine was in used condition. These engines are used as main power units in Coast Guard boats. The exhaust emission concentrations were reduced to mass emissions by the carbon balance technique. Similar emission levels were obtained from the three rebuilt GM6-71 engines with type HV injectors.
