Marine exhaust catalyst

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.

主权项

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 exhaust gas conduit to receive exhaust therefrom, the exhaust emission aftertreatment device including a catalyst in the exhaust passage to reduce one or more exhaust constituents and thermal insulation fixed about the catalyst to reduce an outer temperature of the exhaust emission aftertreatment device while maintaining a desired temperature of the catalyst during operation of the engine, the exhaust emission aftertreatment device being structured without a liquid coolant passageway to reduce temperature thereof.
