This configuration provides increased packaging space adjacent the first leg for any valving that may be required to control the direction and destination of exhaust flow in recirculation to an EGR valve or downstream to a catalytic converter.

    Abstract: An air gap-insulated exhaust manifold (10) for a supercharged internal combustion engine (1), preferably of a motor vehicle has an engine flange (11) fastening the exhaust manifold to an engine block (2) and a turbine flange (12) fastening the exhaust manifold to a turbine (8) of an exhaust gas turbocharger (7). Two inner pipes (13, 14) lead from an inlet opening, for exhaust gas, adjacent to the engine flange to an outlet opening (18), for exhaust gas, adjacent to the turbine flange. An outer pipe (15) envelopes the two inner pipes, forming an air gap insulation (21), and extends from the engine flange to the turbine flange. A separation partition (16) separates, in the interior space (22) of the outer pipe, two interior spaces (23, 24), in which one each of the two inner pipes is arranged. Reduced wear is achieved with the partition arranged loosely at the turbine flange.

  • Patent number: 8899029
    Abstract: Apparatuses for marine propulsion systems having an internal combustion engine comprise an exhaust conduit conveying exhaust from the internal combustion engine; a cooling jacket on the exhaust conduit; and a cooling passage between the exhaust conduit and the cooling jacket. The cooling passage guides flow of cooling liquid from upstream to downstream towards a location where the cooling liquid is mixed with exhaust in the exhaust conduit. First and second baffles are axially spaced apart and extend transversely with respect to the cooling passage so as to disperse the flow of cooling liquid at the location where the cooling liquid is mixed with the exhaust, thereby reducing reversion of cooling liquid in the exhaust conduit. At least one catalyst and at least one oxygen sensor are disposed in the exhaust conduit. The oxygen sensor is adjacent to and oriented parallel to a downstream face of the catalyst so that exhaust flows perpendicularly across the sensor.
