A muffler (40) devised particularly for use with an engine of the type used on unmanned aerial vehicles (UAVs), and a UAV (10) having an engine (30) fitted with the muffler (40). The muffler (40) comprises a body (51) having an interior chamber (60). The muffler body (51) has a first end section (53) and a second end section (55). The first end section (51) is adapted for mounting onto the engine (31) by way of a first mount (81), with the interior chamber (60) in communication with an exhaust outlet of the engine (31) to receive exhaust flow therefrom. The second end section (53) is adapted to be mounted by way of a second mount (82) in a manner resisting movement with respect to the engine (31). In one arrangement, the second mount (82) is configured to yieldingly resist movement with respect to the engine (30). In another arrangement, the second mount (82) is configured to mount the second end section (55) under a preload resisting movement of the second end section with respect to the engine (30).

An exhaust manifold heat dissipation cover coupling device for thermal stress and vibration deflection is proposed. The device has a function of preventing wear of a heat dissipation cover to couple an exhaust manifold heat dissipation cover, the device being able to improve the durability of various parts including a heat dissipation cover by attenuating multi-directional vibration that is transmitted from an exhaust manifold when the heat dissipation cover is installed outside the exhaust manifold, being able to prevent damage to parts due to thermal stress by flexibly coping with thermal deformation such as thermal contraction or thermal expansion even if the thermal deformation is generated by high-temperature heat transmitted from the exhaust manifold, and being able to prevent frictional damage of the heat dissipation cover due to friction by a component that slides to attenuate vibration.

An exhaust gas treatment assembly for an exhaust gas system of an internal combustion engine includes a housing defining a longitudinal axis. A first exhaust gas treatment unit is inserted in the housing and has a first casing and at least one first exhaust gas treatment unit carried in the first casing. A second exhaust gas treatment unit is inserted in the housing and has a second casing and at least one second exhaust gas treatment unit carried therein. A locking arrangement is for locking a first exhaust gas treatment unit in the housing at least against movement in the direction of the longitudinal axis in a locked state, wherein, when the first exhaust gas treatment unit and the second exhaust gas treatment unit are inserted in the housing, the locking arrangement is blocked in the locked state by the second exhaust gas treatment unit.

Systems are provided for a coupling element. In one example, the coupling element comprises a rotating element configured to rotate an aftertreatment device relative to a section of an exhaust passage in response to a force greater than a threshold force.

A connector includes a first buffer member that includes a spiral-shaped wire, a second buffer member that has a substantially annular and flat plate-like shape capable of warping in a thickness direction, a collar member that includes a first flange facing a radially inner side of the first buffer member, and a second flange facing a radially inner side of the second buffer member, and a coupling member. A gap for allowing the second buffer member to move in a radial direction is formed between the second buffer member and a cylindrical portion. A distance between a position of a surface of the second flange and a position of a lowest end of the collar member is greater than a distance between a position of a surface of the first flange and the position of the surface of the second flange in a view in an axial direction.

A heating element for a vehicle exhaust gas purification device is provided and is to be disposed in an exhaust gas duct. The heating element extends around a central axis. and comprises a central support defined around the central axis, a heating grid extending radially around the central support, and a liaison element. The liaison element comprises a plurality of mounting brackets comprising at least a first part connecting the mounting brackets to the heating grid, at least a second part connecting the bracket to the duct, intended to be directly or indirectly attached to the duct, and at least one intermediate section connecting the first connecting part to the second connecting part. The connecting element is at least partially radially flexible.

A bayonet joint having a connector with bayonet tabs arranged on the exterior of the connector, a tubular body with at least one external bayonet contour arranged on the exterior of the tubular body and a bayonet ring with inward facing bayonet hooks and at least one inward facing internal bayonet contour. In an assembled state of the bayonet joint, the connector, tubular body and bayonet ring are in a locking orientation relative to one another. The bayonet ring surrounds an outside of the connector and the tubular body in the radial direction and secures the connector and the tubular body against removal from the bayonet ring.
