| Abstract | This report documents the results of emissions tests performed on three old and two new outboard engines. Tests of the emissions were made before and after water contact. Older engines were tested in as-received condition, tuned to factory specifications and retested. After being tuned, these engines showed improvements in emissions and fuel consumption. The new engines with improved ignition and combustion chamber design and crankcase drainage recycling showed less emission and better fuel consumption characteristics than the older engines. The results of these tests were used to calculate the emissions impact of the United States Coast Guard outboard fleet for comparison with the emissions impact of other Coast Guard vessels and vessels in general. |
