Exhaust injection muffler

摘要

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.

1. An apparatus, comprising:
a marine genset including an internal combustion engine and an electric power generator mechanically driven by the engine; an exhaust manifold for the engine including an exhaust gas conduit; and an exhaust emission aftertreatment device including an exhaust passage in fluid communication with the conduit to receive exhaust therefrom, the exhaust emission aftertreatment device including a catalyst in the exhaust passage to reduce one or more exhaust constituents; an exhaust muffler including a container having a coolant inlet to receive coolant, the container further including an exhaust inlet in fluid communication with the exhaust passage to receive exhaust therefrom, the container further including an exhaust outlet to allow exhaust to flow from the container, wherein exhaust flows into the container below a coolant level; and an exhaust cooler located downstream of the catalyst and upstream of the exhaust muffler, wherein the coolant inlet is in fluid communication with the exhaust cooler to receive coolant therefrom.
