摘要： A propulsion system has an internal combustion engine including an exhaust manifold and an engine air intake, an exhaust port fluidly connected to the exhaust manifold, a fresh air intake fluidly connected to the engine air intake and a filter assembly including adsorbent material and being configurable between a loading configuration allowing for filtration of at least some components of an exhaust gas of the engine, and a purging configuration allowing for removal therefrom of at least some of the components of the exhaust gas. In the loading configuration, the filter assembly is fluidly connected between the exhaust manifold and the exhaust port. In the purging configuration, the filter assembly is fluidly connected between the fresh air intake and the engine air intake. Above a threshold effective engine speed of the engine, the filter assembly is in the purging configuration. A method for treating exhaust gas is also described.

摘要： A fuel system for an engine is provided. A fuel injector of the engine has an injector inlet and an injector outlet. The fuel system includes a fuel vapor separator, a fuel supply conduit, an injector conduit, a fuel return conduit, and a vapor return conduit. A first end of each of the fuel supply, injector and vapor return conduits is fluidly connected to the fuel vapor separator. A first end of the fuel return conduit is fluidly connectable to a fuel tank. A second end of the fuel supply conduit is fluidly connectable to the fuel tank. A second end of the injector conduit is fluidly connectable to the injector inlet. A second end of the fuel return conduit is fluidly connectable to the injector outlet. A second end of the vapor return conduit is fluidly connectable to the fuel tank. A marine outboard engine is also provided.
