摘要： A fuel rail permeant collection system includes a substantially impermeable enclosure surrounding a fuel rail on an internal combustion engine. Preferably, the enclosure is in communication with air intake means for the engine, for example, the intake manifold or runners from the manifold to the engine cylinders, such that fuel collected by the enclosure can be evaporated and passed into the intake means for combustion by the engine. The system may be included in a vehicle vapor purge circuit from a fuel tank emissions-control canister system.

摘要： A fuel system for fluidly connecting a fuel tank with an engine includes a low-pressure fuel circuit connected to the fuel tank. A high-pressure fuel circuit connected to the engine is supplied with fuel by the low-pressure fuel circuit. A priming fuel circuit includes a priming fuel conduit and a priming valve. The priming fuel conduit has a first segment and a second segment. The priming valve has an inlet and an outlet. The first segment of the priming fuel circuit interconnects the low-pressure fuel circuit and the outlet of the priming valve. The second segment of the priming fuel circuit interconnects the high-pressure fuel circuit and the inlet of the priming valve. The priming valve is operable to control a flow of fluid through the priming fuel conduit to thereby selectively connect and disconnect the high-pressure fuel circuit and the low-pressure fuel circuit.

摘要： An exhaust gas recirculation valve assembly for controlling the recirculation of exhaust gas in an internal combustion engine having a base with an exhaust gas chamber formed therein, a valve member mounted within the exhaust gas chamber for metering the flow of exhaust gas therethrough, a one piece bearing having upper and lower bearing members for precise positioning of the valve member within the exhaust gas chamber, and a valve stem support assembly for mounting the valve stem relative to the actuator having means for allowing lateral movement between the actuator and the valve member thereby eliminating side-to-side loading and resultant binding of the precisely positioned valve member within the bearing.
