ABSTRACT:
An apparatus and method suitable in controlling a level of noxious fumes and visible smoke discharging from diesel engine exhaust gases. In a purification mode, a stream of relatively dirty exhaust gases and discharged cooling liquid from the engine are mixed together; liquid entrained in the mixture and particulate matter in the mixture are then removed and noxious substances in the resulting exhaust gases are adsorbed. In a regeneration mode, the exhaust gas is relatively clean so that streams are kept apart to avoid mixing so that the exhaust gases can adsorb the previously adsorbed noxious substances. The purification mode arises when the marine diesel engine is running at slow speed and combustion takes place inefficiently. The regeneration mode arises when the marine engine is running at high speed and combustion takes place efficiently or else noxious substances have been adsorbed substantially to capacity.
