In an exhaust system of an internal combustion engine, an exhaust pipe is reliably bent and deformed during vehicle rear collision while improving drainage performance in the exhaust pipe in normal times. The exhaust system 1 includes a second pipe 17 corresponding to a downstream end part of an exhaust pipe 10 through which exhaust gas flows from an engine 2. The second pipe 17 includes: a fragile part 30 as a starting point of bending deformation of a tail pipe 13; and a partition plate 20 vertically dividing the inside of the second pipe 17 to form, under the partition plate 20, a lower passage 7 to flow water that accumulates in the exhaust pipe 10. The partition plate 20 is in a vicinity of the fragile part 30 and at a position not overlapping with the fragile part 30 in an axial direction of the second pipe 17.

The present invention relates to an exhaust gas dispersion device for an agricultural working vehicle, comprising: a dispersing body into which an exhaust gas discharged from an exhaust port of the agricultural working vehicle flows; a deceleration part coupled to the distributing body to reduce the speed of the exhaust gas flowing into the dispersing body; and a plurality of dispersing holes formed through the dispersing body at positions spaced apart from each other so that the exhaust gas decelerated by the deceleration part is dispersed and discharged out of the dispersing body.

An arrangement for fastening a tailpipe cover to a tailpipe is disclosed. The arrangement has a tailpipe cover, a tailpipe and a bracket. The bracket is arranged on the tailpipe cover. The tailpipe cover can be latched here to the tailpipe at a tailpipe projection, which is arranged on the tailpipe, by the bracket being deflected laterally in the circumferential direction of the tailpipe cover.

A pipe mixer for an aftertreatment system is described for mixing of a reductant and exhaust gas. The pipe mixer comprises a hollow body having a first end and a second end, the body surrounding a mixing channel; an injector mount positioned at the first end of the body; perforations provided on the body for entry of exhaust flow into the mixing channel; directional elements positioned on the body for directing exhaust flow towards the injector mount, the directional elements being positioned between the first end and the perforations wherein each directional element comprises an inlet formed on the body for entry of exhaust flow and a guide provided on an internal surface of the body, the guide having an outlet for exit of exhaust flow.

An exhaust gas outlet system for a motor vehicle has an end pipe and a cover. The end pipe cover has an end pipe cover inner and outer wall constructed with at least two walls. The end pipe cover inner wall is constructed in at least two parts, can be closed radially around the end pipe and can be at least partially arranged in a positive-locking manner on the end pipe so that the end pipe cover inner wall in the state thereof mounted on the end pipe is not axially displaceable. A first annular securing element keeps the end pipe cover inner wall radially fixed on the end pipe. The end pipe cover outer wall can be pushed axially over the end pipe cover inner wall. The end pipe cover outer wall is fixed by means of a locking connection axially to the end pipe cover inner wall.
