摘要： A fuel injector assembly and a low pressure fuel injection system incorporating the fuel injector assembly are provided. The fuel injector assembly includes a fastener housing that functions to secure a reed valve block to a mounting plate which separates the air intake manifold from the crankcase of the internal combustion engine. A fuel injector or check valve is secured to the fastener housing so that fuel directed to the fuel injector passes through the mounting plate and into the crankcase at a location in the vicinity of the air flow outlet from the reed valve block.

摘要： A marine propulsion system (2) with an outboard engine (4) has an oil-fuel mixing valve (16) within the engine cowl (6). A first crankcase pressure driven fuel pump (20) delivers fuel from a remote fuel tank (14) to the mixing valve, and a second crankcase pressure driven fuel pump (22) delivers mixed oil-fuel from the mixing valve to the engine. The arrangement provides adequate fuel pressure to overcome the added pressure drop across a reduced size mixing valve, all fitting within the engine cowl. The crankcase pressure pulses to the fuel pumps are 180.degree. out of phase such that when the first pump is pushing pressurized fuel to the inlet of the mixing valve, the second pump is pulling suctioned oil-fuel from the outlet of the mixing valve, to increase fuel pressure differential and enhance operation of the mixing valve.
