The present disclosure relates to an all-terrain vehicle and an exhaust assembly for an all-terrain vehicle. The all-terrain vehicle includes: a frame, a V-type twin-cylinder engine and an exhaust assembly. The V-type twin-cylinder engine has a first exhaust port and a second exhaust port, and a cylinder corresponding to the first exhaust port is located in front of a cylinder corresponding to the second exhaust port. The V-type twin-cylinder engine is mounted on the frame. The exhaust pipe group has a first end coupled to the first exhaust port, a second end coupled to the second exhaust port, and a third end coupled to a pipe of the muffler. The exhaust pipe group is divided into at least two exhaust pipes, and adjacent exhaust pipes are flexibly coupled.

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.

A replacement kit for use with a motor vehicle that was originally equipped with an exhaust system including an exhaust manifold and a catalytic converter welded thereto. The replacement kit includes a replacement catalytic converter arranged for use during use of the motor vehicle on public roads. Rather than welding, the replacement catalytic converter attaches to the exhaust manifold using a clamp to form a gas-tight seal. The clamp is arranged to move from the closed position to an open position to enable disengagement of the replacement catalytic converter from the exhaust manifold and substitution of a bypass pipe in place of the replacement catalytic converter to increase performance characteristics of the vehicle during off-road use.

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.

An illustrated view of an exemplary air filter for reducing emissions is presented. The air filter is useful for removing toxic gases from the air surrounding a combustion engine of a vehicle is presented. The air filter is useful for scrubbing the ambient air for removal of toxic contaminants such as carbon dioxide and thus reducing harmful emissions of a vehicle. The air filter though described for a vehicle can also be used in industry settings as well as at home. The air filter is recyclable. Although a vehicle is shown, it is an example only. Other applications are possible and have been contemplated for the air filter 100 including, but not limited to, commercial applications, home applications, industrial applications, etc.

Systems and methods are provided for a combined spark arrestor and muffler assembly. In one example, a system may include a combined housing, the combined housing including a spark arrestor portion including a plurality of stator fins, and a muffler portion including acoustic packing, the muffler portion fluidically coupled to the spark arrestor portion via a first sliding joint and a second sliding joint. In this way, a single component of a vehicle exhaust system may reduce sparks and/or carbon deposits in exhaust gas, while also reducing exhaust noise.

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.

The present invention provides for a profiling mount device for redirecting the exhaust energy of a compactor onto an asphalt surface and a method to use it. The profiling mount device to cause surface moisture located on the asphalt surface to be dried. A dielectric sensor is attached to the profiling mount device such that it can take a dielectric constant reading at the desired location where the exhaust energy dries the asphalt surface. The dielectric constant reading is taken by a dielectric profiling system (DPS). The dielectric profiling system cannot accurately read the dielectric constant of an asphalt section when surface moisture is present.

The invention presented is a crossover section for a vehicle exhaust system that includes a middle pipe and two outer pipes, each outer pipe in contact with and attached to the middle pipe. Diversion gates extend from the middle pipe into each of the outer pipes to divert a sample of exhaust gas into the middle pipe. A sensor, such as an oxygen sensor, is provided to measure one or more components of the combined exhaust. Also provided is an exhaust system that includes the inventive crossover section and a vehicle that includes one or more of the inventive exhaust systems.
