Engine e.g. diesel engine, for vehicle, has connection conduit connecting gas inlet and valve, and air supply line comprising supercharged air cooler for cooling part of gas circulating in exhaust gas re-circulation loop by coolant

摘要

The engine (12) has an air supply line (14) including an exhaust gas re-circulation loop (10) with a valve (28) that controls exhaust gas flow. A connection conduit (22) connects an exhaust gas inlet (24) and the valve. A metallic structured particle filter (26) filters particles, and is arranged in the conduit. The line has a supercharged air cooler (44) to cool a part of gas circulating in the loop by coolant. The filter has a catalytic phase that comprises an active oxidation phase including elements selected from transition metal oxides and/or rare earth oxides.
