    Abstract: Provided is an exhaust system for an engine in which a fastening force of a fastener hardly decreases. An exhaust system for an engine includes: an exhaust passage component of ferrous metal; and a fastener that fastens the exhaust passage component to other parts, the exhaust passage component including a pressure receiving surface that receives a fastening force of the fastener. The oxide film of triiron tetraoxide is formed on the pressure receiving surface of the exhaust passage component. It is preferable that the oxide film of triiron tetraoxide be also formed on an outer surface other than the pressure receiving surface of the exhaust passage component. It is preferable that the oxide film of triiron tetraoxide be also formed on an inner surface of the exhaust passage component.

    Abstract: A muffler system with a muffler in one aspect of the present disclosure includes an outer wall, and a first separator and a second separator that partition a muffling space. An attachment member is arranged on an outer surface of the outer wall, and a muffler pipe to communicate with the muffling space is arranged to pass through an attachment member hole in the attachment member. The outer surface of the outer wall includes a first area and a second area. The first area is located between a first end of the muffling space and the first separator, and the second area is located between a second end of the muffling space and the second separator. The attachment member is welded to the first and second areas of the outer surface of the outer wall.

    Abstract: An electric heating support includes a honeycomb structure having an outer peripheral wall and interior porous partition walls defining a plurality of cells forming a flow path. A pair of electrode layers are disposed on a surface of the outer peripheral wall so as to face each other across a central axis of the honeycomb structure. Protective layers cover the electrode layers, respectively, such that at least a part of each electrode layer is exposed. A pair of metal terminals are provided on the electrode layers. Each electrode layer is composed of a metal-ceramic mixed member. A portion of each electrode layer that is exposed from the protective layer is electrically connected to each of the pair of metal terminals.

    Abstract: A noise muffler for an air moving device can include a housing with a housing inlet, a housing outlet, and at least a first foam component and a second foam component. The first foam component and the second foam component are placed within a cavity of the housing and define an air passageway. The first foam component and the second foam component redirect air flow through the cavity in three dimensions in order to muffle noise generated by the air moving device.

    Abstract: A housing connection element (10) for a housing of an exhaust gas treatment assembly unit of an exhaust system, especially for an internal combustion engine, includes a first housing part (16) with an essentially cylindrical first connection area (18) for connection to a circumferential wall (14) of a housing (12) of an exhaust gas treatment assembly unit. A tapered area (20) is adjacent to the first connection area (18). An annular, second housing part (40) is connected to the tapered area (20). A second connection area (46) is provided for connection to an exhaust gas-carrying component of an exhaust system. At least one sensor sleeve (48, 50) is in a sleeve receiving area (24) of the first housing part (16). The sleeve receiving area (24) is formed in the tapered area (20).
