Exhaust gas outlet system for a motor vehicle, motor vehicle having such an exhaust gas outlet system, and method for producing an exhaust gas outlet system
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.
TRACTOR
A tractor including: an engine mounted on a traveling body; a post-processing device configured to purify exhaust gas of the engine; and a tail pipe long in an up-down direction and configured to emit exhaust gas having passed through the post-processing device to the outside. The post-processing device is arranged in a standing posture in front of an operation unit on the traveling body so that the exhaust gas flows from the bottom to the top. An upwardly protruding outlet pipe is provided on an upper surface side of the post-processing device. The inner diameter of an exhaust gas inlet side of the tail pipe is set larger than the outer diameter of the outlet pipe which is inserted and communicated with the exhaust gas inlet side of the tail pipe.

Pipe Mixer for an Aftertreatment System
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.

Straddle type vehicle
A straddle type vehicle 1 having at least one reflecting portion 30 for reflecting a radar wave transmitted from a radar equipment. The reflecting portion 30 is provided on a cap member 40 mounted on a rear end portion 9b of an exhaust pipe 9, and the reflecting portion 30 is arranged below left and right tail lights 19 when viewed from a rear side of a vehicle body.
EXHAUST LINING HAVING A CONNECTING ELEMENT
An exhaust lining for an exhaust system of a motor vehicle has a first connecting element clamped between a first and second pipe. The first pipe forms a tailpipe. The second pipe forms a tailpipe cover. The tailpipe cover has a tubular inner part held on by means of the first connecting element which clings onto the first pipe via by means of a lever mechanism. A load arm of the lever mechanism, having the distance A, is shorter than an effort arm, having the distance B. The length of the effort arm is precisely defined, because the end of the effort arm lies against the first pipe via a punctiform contact area. A first contact surface of a clamping spring is designed offset from the longitudinal extent of a main body of the first connecting element to save space in the longitudinal direction of the main body.
Vehicle
A golf car includes an engine and a shroud that covers a cylinder body. The shroud communicates with a muffler cover, which covers a muffler. A silencer is provided at an outlet of the muffler. An elastic exhaust duct is connected to an exit end portion of the muffler cover. An undercover is located lower than the engine, and defines an underside of an engine room. The undercover includes an opening at a more rearward position than the muffler in a side view. The exhaust duct is routed above the undercover, includes a rearward end portion at the opening, and is fitted to the opening. Holders hold sound absorbing members on an inner circumferential surface of the exhaust duct.

EXHAUST GAS DISPERSION DEVICE FOR AGRICULTURAL WORKING VEHICLE
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.
