    Abstract: This disclosure relates generally to a prime mover system. More specifically, this disclosure relates to a prime mover exhaust system that can prevent the accumulation of debris (e.g., soot or unburned fuel) in the prime mover system. In accordance with at least one embodiment described and recited herein, a self-cleaning prime mover exhaust system is provided. The prime mover exhaust system includes an exhaust tip, an exhaust pipe, and a cleaning tube. The exhaust tip is configured to eject exhaust out of the prime mover exhaust system, the exhaust pipe is configured to direct the exhaust away from a prime mover, and the cleaning tube is configured to accumulate debris exiting from the exhaust pipe and configured to vacuum the debris out of the self-cleaning prime mover exhaust system through the exhaust tip using the Venturi effect.

    Abstract: A work vehicle such as a tractor including a cooling fan (12a) arranged in front of the vehicle's engine main body (1), and is configured to feed air to the engine main body. The work vehicle further includes a DPF (19), which is arranged on one side of the engine main body and purifies exhaust gas exhausted from the engine main body, and an engine hood (7), which covers the engine main body, the cooling fan, and the DPF. An outside air intake port (21) is formed in both side surfaces of the engine hood at a position further forward than the cooling fan. On both side surfaces of the engine hood, a first opening (30) capable of exhausting air inside the engine hood in a direction away from the vehicle's operation seat in side view is formed in a position facing the DPF in the lateral direction.

    Abstract: An exhaust system is for a marine propulsion device having an internal combustion engine. A catalyst housing has a housing inlet end that receives an exhaust gas flow from the internal combustion engine into the catalyst housing and an opposite, housing outlet end that discharges the exhaust flow out of the catalyst housing. A catalyst is disposed in the catalyst housing. The catalyst has a catalyst inlet end that receives the exhaust gas flow and an opposite, catalyst outlet end that discharges the exhaust gas flow. A catalyst mantel is on an outer periphery of the catalyst. The catalyst mantel has a mantel inlet end and an opposite, mantel outlet end. A radial flange is on at least one of the mantel outlet end and mantel inlet end. A connector mates with an inner diameter of the catalyst housing. The radially extending flange of the catalyst mantel is axially sandwiched between the connector and a radially inner shoulder of the catalyst housing.
