An apparatus for attachment to a tailpipe of a vehicle is disclosed herein. The apparatus includes a filter body, a removable filter medium, a locking collar and a removable front cover. The filter medium preferably comprises of any materials that are deemed by the scientific community as sorbents that are capable of absorbing exhaust gases such as carbon dioxide, nitrogen oxides, carbon monoxide, sulfur dioxide, particulate matter, or other hydrocarbons.

An exhaust treatment system for a work vehicle includes a selective catalytic reduction (SCR) system having an SCR outlet for expelling treated exhaust flow therefrom, a flow conduit in fluid communication with the outlet, an exhaust sensor positioned within the flow conduit downstream of the outlet, and a flow mixer positioned upstream of the exhaust sensor. The flow mixer has an end wall defining sector openings circumferentially extending between first and second sector sides and radially between radially inner and outer sector ends. Moreover, the flow mixer has swirler vanes, where each of the swirler vanes extends circumferentially from the first sector side of a respective one of the sector openings and radially between radially inner and outer vane ends. Particularly, the radially outer vane end of each of the swirler vanes is spaced apart from the radially outer sector end of the respective one of the sector openings.

An exhaust assembly includes a first tailpipe having an exit end and a curved portion along at least a portion of a length of the first tailpipe. The exhaust assembly further includes a baffle surrounding the first tailpipe at the exit end and defining a plurality of perforations therethrough. The exhaust assembly further includes a pair of shields. Each shield is attached to and at least partially surrounds each of the baffle and the first tailpipe. Each shield extends from a first end proximal to the exit end of the first tailpipe to a second end distal to the exit end of the first tailpipe. Each shield engages the baffle at the first end and engages the first tailpipe at least at or proximal to the second end. The pair of shields is adapted to allow fluid flow to or from the plurality of perforations of the baffle.

A vehicle that can cool an ignition coil is provided. The vehicle has an engine having a cylinder head and an ignition coil with a first end exposed from the cylinder head, a CVT that varies and outputs rotary power from the engine, and an exhaust duct having a first exhaust port for exhausting a gas within a CVT case to outside of the CVT case, and a second exhaust port for exhausting a part of the gas flowing to the first exhaust port to outside of the CVT case, wherein the second exhaust port is provided for exhausting the gas within the CVT case to at least a part of the first end of the ignition coil.

A support assembly for supporting an upright engine exhaust pipe on an exterior wall of a truck cab at a location below an outlet of the exhaust pipe. The support assembly allows limited cab motion relative to the exhaust pipe.

A vehicle exhaust evacuation system includes an adapter secured to an end of a vehicle tailpipe and a nozzle assembly secured to the end of a flexible hose for carrying vehicle exhaust outside of a building. The nozzle assembly has an aluminum cartridge removably secured in a rubber boot. Magnet assemblies are secured to the aluminum cartridge. Openings in the adapter allow ambient air to flow over the magnet assemblies to lengthen the life of the magnets.

A compact slip-in spark arrester having an interior shell (125) with a circular cross-section changing in diameter along its axial length which is axially aligned between an inlet cap member (115) and an outlet cap member (145). The tubular center section (130) of the interior shell (125) containing a centrifugal whirling means to remove any particulate matter from the exhaust flow by means of centrifugal force or deflection and trapping the particulate matter in an outer chamber (155) between the interior shell (125) and existing silencer shell (100).

A support assembly for supporting an upright engine exhaust pipe on an exterior wall of a truck cab at a location below an outlet of the exhaust pipe. The support assembly allows limited cab motion relative to the exhaust pipe.

A component for a mixer of a vehicle exhaust system, according to an exemplary aspect of the present disclosure includes, among other things, a doser mount comprising a curved body having a center boss with a doser opening defining a doser axis. The curved body includes at least a first mating surface configured to receive a first mixer shell defined by a first dimension and a second mating surface configured to receive a second mixer shell defined by a second dimension different than the first dimension.
