摘要： An exhaust gas heater system for an exhaust system of an internal combustion engine includes a housing and a heating element. The housing includes an outer peripheral wall disposed about a central axis and defining an interior hollow space configured to receive exhaust gas from an exhaust pipe of the exhaust system such that the exhaust gas flows through the interior hollow space. The heating element is positioned within the hollow space and including a first end and a second end. The heating element forms a zig-zag shape extending in a radial direction relative to the central axis.

摘要： An exhaust gas heating unit for an engine includes a housing and a heating element. The housing includes a tubular peripheral wall and has an interior hollow space. The heating element has first and second ends and extends longitudinally therebetween to form a spiral shape within the interior hollow space. The heating element includes a thermally conductive sheath, an electrically conductive resistance element that extends longitudinally within the external sheath, and an electrically insulating material disposed about the resistance element between the resistance element and the sheath. A heat transfer member is positioned within the interior hollow space and is formed from one or more strips of thermally conductive material. The strips contact the external sheath at a plurality of locations between the first end and the second end. The heat transfer member has a corrugated shape that follows the spiral shape of the heating element.

摘要： A half shell joint structure includes a first joint portion formed at an edge of a first half shell and a second joint portion formed at an edge of a second half shell. One of the first joint portions and the second joint portion has a protruding portion protruding by a predetermined interval in an outer diameter direction. The protruding portion has a flat contact surface, and when the first joint portion and the second joint portion overlap with each other, the contact surface contacts an inner surface of the joint portion that the contact surface faces.
