When catalytic converters are used for cleansing of exhaust gas from two - stroke marine engines, new issues must be brought up in combination with prior technology. Therefore, a study was made of V6, 2600cc engines having a large volume of hydrocarbon emissions with respect to three issues: It was found that physical adsorption was a significant factor in catalytic degradation resulting from direct contact with seawater. The cleansing levels obtained when a marine engine is equipped with a catalyst converter were found by clarifying the extent of effects of catalyst volume, performance and temperature. The reduction obtained in exhaust emissions allowing for a degradation factor, is shown in a catalytic converter heated to the maximum temperature of 960 °C.
