A prechamber assembly includes a cylinder head including a coolant cavity, a prechamber body located within the cylinder head, the prechamber body including a nozzle, and an annular sleeve radially surrounding a portion of the prechamber body. The sleeve includes a plurality of coolant inlet holes. A portion of the prechamber body is radially spaced from the sleeve to form a coolant sleeve annulus extending along a length of the prechamber body above the coolant inlet holes. The coolant cavity and the coolant sleeve annulus are in fluid communication through the plurality of coolant inlet holes.

A flexible line segment for the exhaust system of an internal combustion engine, with an annularly corrugated or helically corrugated metallic bellows, for exhaust gas flow therethrough, and a line segment arranged upstream in reference to the metallic bellows, with a precipitation device provided in the line section, arranged upstream in reference to the metallic bellows or mounted thereat. The precipitation device is provided for urea derivatives or urea entrained in an edge layer of the exhaust gas flow from an oversaturated edge layer of the exhaust gas flow.

An inlet port (17A) of a first exhaust gas purifying device (16) is provided on a side opposite to an engine (8) by sandwiching an axis (O1-O1) of a cylindrical body (17) of the first exhaust gas purifying device (16). An exhaust pipe (26) connecting the engine (8) and the first exhaust gas purifying device (16) is constituted by a lateral pipe line (27) extending in a left and right direction of an upper revolving structure (3) on a front side of the first exhaust gas purifying device (16) and having a bellows pipe (28) in the middle for absorbing relative displacement between the engine (8) and the first exhaust gas purifying device (16) and a bent pipe line (29) bent having a U-shape rearward from a tip end side of the lateral pipe line (27) and connected to the inlet port (17A) of the first exhaust gas purifying device (16).

A modular exhaust manifold 1 for a motor vehicle, with multiple adjoining manifold pipe modules, having: at least one engine flange, via which an inlet connection pipe of the manifold pipe modules can be connected to a cylinder head of the motor vehicle; at least one manifold pipe module, configured as a collector pipe module and having a contact flange, via which the exhaust manifold can be connected to an exhaust system of the motor vehicle, the respective manifold pipe modules having an overlap contour of a length a that permits the telescoping of two manifold pipe modules to an insertion depth t for coupling purposes, at least two manifold pipe modules being identical in shape, and a variation of the insertion depth t of at least 5 mm to 30 mm or 10 mm or 15 mm or 20 mm or 25 mm being obtained by the formation of length a of the overlap contour. A method for producing a manifold formed from multiple adjoining manifold pipe modules.

An engine device in which an exhaust gas purification device can be disposed without substantially increasing mounting width dimensions (height, lateral width, front and rear width) of an engine. The engine device includes the exhaust gas purification device connected to an exhaust manifold of the engine, an oil pan disposed on a bottom of the engine, a support body for linking the exhaust gas purification device to the oil pan, so that the exhaust gas purification device is supported by the oil pan.

An exhaust casing for use with a turbocharger includes a hollow body that has two mutually opposed large walls, which extend along first and second major dimensions of the hollow body and are spaced apart by a minor dimension of the hollow body, the hollow body defining a plenum and an inlet nozzle opening into the plenum along the minor dimension of the hollow body. The casing further includes an outlet nozzle opening from the plenum along one of the major dimensions of the hollow body.

A flexible pipe element is provided formed as a metal bellows with at least one corrugated bellows section and a bellows brim, which forms one end of the metal bellows, and a connection element for connecting the metal bellows to a continuing pipe part or to a connector, with the connection element having a connection area for abutting a contact area of the bellows brim. An annular bulge is formed in the contact area of the bellows brim and/or in the connection area of the connection element projecting beyond an average level of the contact area and/or an average level of the connection area in order to form a linear seal between the contact area and the connection area. A method for producing such a flexible line part is also provided.

A support for an exhaust stack comprises a first bracket including a first base joining a first extension and a second extension, the first base being fixed to the vehicle, and a second bracket including a second base joining a third extension and a fourth extension, the second base being fixed to the exhaust stack. A member is disposed between the first base and the second base. The member has a first end and a second end. A first fastener is accepted by the first end and extends between the first extension and the second extension. A second fastener is accepted by the second end and extends between the third extension and the fourth extension.

An exhaust system for an internal combustion engine includes an exhaust pipe, and a vane mixer attached to an upstream pipe end of the exhaust pipe and including a fluid injector mount, and a fluid injection side port in the injector mount and fluidly connected to an exhaust passage in the vane mixer. The vane mixer further includes a vane extending across the exhaust passage and dividing the exhaust passage into a major flow area and a minor flow area. The minor flow area is in overlapping angular alignment, circumferentially around a longitudinal exhaust passage axis, with the fluid injection side port.

The invention relates to a line element (100) having an inner element (IE), an outer element (AE) surrounding the inner element, and a sliding layer (131, 132) in the form of an anti-friction lacquer, which is arranged in the contact region on the inner element (IE) and/or on the outer element (AE).
