    摘要: An electromagnetic fuel injector having improved wear characteristics comprises a body having a fuel inlet and a fuel outlet. A valve seat is sealably connected to the body, and a moveable valve member positioned at the fuel outlet for controlling the flow of fuel from the outlet comprises a valve outlet element that provides a sealing interface with the valve seat. The valve member and included valve outlet element further comprise wear surfaces that are subject to repeated impact and/or sliding contact; at least a portion of these wear surfaces comprise an applied layer of diamond-like carbon (DLC) stabilized by inclusion of greater than 30 weight percent of a carbide-forming material selected from the group consisting of silicon, titanium, and tungsten.

    摘要: A by-pass fuel system configured so that in the event diesel fuel has waxed and/or ice crystals have formed such that the fuel cannot pass easily through the fuel pump fuel strainer, the diesel fuel is selectively able to pass through an auxiliary fuel port via a by-pass valve, thereby ensuring adequate fuel flow to the diesel engine. Return fuel heated by the engine is preferably directed directly onto the fuel pump fuel strainer to help dissolve the waxing and crystallization. An auxiliary coarse fuel strainer optionally provides coarse fuel straining of the by-passed fuel.

    摘要: A fuel sender unit is provided for deployment on a vehicle having a fuel tank. The fuel sender unit includes a float arm configured to move in relation to the volume of fuel held within the fuel tank. A fuel level sensor is coupled to the float arm. The fuel level sensor produces a resistance that varies with the position of the float arm to thereby produce a multi-slope sender profile including at least first, second, and third successive profile segments. The first profile segment has an average slope that is greater than that of the second profile segment, and the second profile segment has an average slope that is greater than that of the third profile segment.
