In-vehicle equipment is disposed between the high-voltage battery and the high-voltage devices, and the in-vehicle equipment is in an inclined state where an upper surface of the in-vehicle equipment is inclined in a front-rear direction such that the in-vehicle equipment has a shorter dimension in the front-rear direction than a dimension in a horizontal state where the upper surface becomes horizontal.

A muffler heat protection system for a vehicle includes a muffler heat shield configured to extend circumferentially around a portion of a muffler, the muffler heat shield having a first end and a second end; a heat shield extension secured to the first end of the muffler heat shield; a double wall exhaust pipe including an inner exhaust pipe and an outer covering pipe disposed over the inner exhaust pipe, the outer covering pipe having a first end portion and a second end portion, and the inner exhaust pipe having a first end portion and a second end portion; wherein the second end portion of the outer covering pipe is welded to the muffler at a welded connection seam; and wherein the heat shield extension projects outward from the muffler heat shield over the welded connection seam.

A component for an exhaust system of an internal combustion engine includes a component housing (22) elongated in the direction of a housing axis with an exhaust gas inlet (21) and with an exhaust gas outlet (24) and a carrier assembly unit (28) for connecting the component (16) to a carrier structure. The carrier assembly unit (28) includes a carrier rod (46), the carrier rod (46) being fixed to the component housing (22) in at least two fastening areas (60, 62) located at spaced locations from one another along the carrier rod (46). The carrier assembly unit (28) has at least one carrier rod connection area (52, 54) for connection to the carrier structure.

An exhaust discharge system and method of assembling is disclosed. The exhaust discharge system may comprises an ejector tube and an exhaust stack. The ejector tube includes an outlet having an outlet cross-section. The ejector tube is configured to convey treated exhaust to the outlet. The outlet cross-section is oriented at an outlet angle to a first horizontal plane. The exhaust stack includes a first conduit and a second conduit. The second conduit includes an exit port. The exit-port cross-section is oblong in shape.

An exhaust system for an internal combustion engine of a vehicle includes an exhaust gas pipe, at least one branch pipe branching off from the exhaust gas pipe, for example, a pressure pipe (22), as well as at least one support device (38) supporting at least one branch pipe in relation to an exhaust system component. The support device (38) includes a carrier element (42) fixed to the exhaust system component, a clamping element (44) pressing at least one pressure pipe (22) against the carrier element (42), as well as a clamping (tensioning) device (58) acting between the carrier element (42) and the clamping element (44) for tensioning the clamping element (44) in relation to the carrier element (42).

A device for capturing in-port ship exhaust gases is designed to be connected to a ship, when the ship has at least one funnel that serves as an outlet for exhaust gases. The device includes at least one collection device, including a hood designed to connect to the funnel at the exhaust outlet so as to collect the exhaust gases coming out of the funnel, a handling unit designed to move the collection device and position it at the exhaust outlet, a first constraint configured to interconnect or disconnect the collection device and the handling unit by command so as to create a handling configuration in which the collection device and the handling unit are interconnected by the first constraint and can be moved as one, and a collection configuration in which the collection device collects the exhaust gases and the connection achieved by the first constraint is released, and a second constraint configured to exert a magnetic attraction force, by command, intended to put the first constraint into the handling configuration.

Exhaust assemblies for vehicles and methods of installing exhaust systems on vehicles are disclosed. An exhaust assembly for a vehicle includes an exhaust inlet to receive combustion products from a drive unit, a catalytic converter to control emissions from combustion products received by the exhaust system, and a first piping assembly coupled to the exhaust inlet and the catalytic converter.

An engine device including an exhaust gas purification device above cylinder head through a support pedestal. The support pedestal has a flat portion on which the exhaust gas purification device is mounted, and a plurality of legs which protrude downward from the flat portion and are fixed to the cylinder head. The flat portion and the leg portions are formed integrally. Portions between the legs are each formed in an arch-shape.

An exhaust gas treatment assembly unit for an exhaust system of an internal combustion engine includes a tubular outer housing (12) elongated in a direction of an outer housing longitudinal axis (L.sub.A), a tubular inner housing (14) elongated in the direction of an inner housing longitudinal axis (L.sub.I), an exhaust gas treatment unit (16) being carried in the inner housing (14), and a locking fixing device (24) detachably fixing the inner housing in the outer housing. The locking fixing device (24) includes a locking fixing element (26) held at the inner housing (14) in both axial directions with a radially outwards prestressed locking meshing area (28). In association with the locking meshing area (28), a locking receiving area (42) at the outer housing (12), interacts with the locking meshing area (28) for holding the inner housing (14) in the outer housing (12) in at least one axial direction.

Catalytic converter anti-theft devices and systems are described.
