ABSTRACT:
An automobile combustion engine having at least one exhaust port is provided with a tubular insert within an engine casing. This tubular insert is accommodated within an exhaust passage leading from at least one combustion chamber towards the exhaust port, and is held in position by the interposition of a heat insulating member made of heat insulating material having a lower thermal conductivity than that of material of the engine casing and/or the tubular insert. Heat transfer from the tubular insert to the engine casing is minimized by the interposition of the heat insulating member thereby avoiding a possible reduction of the temperature of an exhaust gas flowing through the tubular insert towards a subsequent process station.
