An internal combustion engine is coupled to an electric power generator. An exhaust manifold for the engine includes an exhaust gas conduit. A housing includes a catalyst in fluid communication with the conduit to receive exhaust produced by the engine. The catalyst is operable to reduce one or more constituents of the exhaust.

Exhaust injection muffler

An apparatus includes a housing having a ventilation opening. A component such as a generator set can be disposed within an interior space of the housing. A baffle can be disposed within the interior space of the housing at a location that obstructs an acoustic line of sight between the ventilation opening and the component to eliminate or otherwise reduce a sound signature of the component. The baffle can also be configured to accumulate water from the ventilation opening. A drain can also be provided to aid in the removal of water accumulated by the baffle and route the water outside the housing.
