    摘要: An apparatus for attenuating fuel pump noise in a direct injection internal combustion engine. In one proposal, the direct injection fuel nozzle is suspended from a fuel rail in a fashion that avoids direct metal-to-metal contact between the injector and the engine block. The direct injection nozzle may also be connected to the fuel rail by a pair of spaced-apart seals which equalize the longitudinal pressure on the nozzle during operation. Enlarged diameter fuel reservoirs and/or a restricted orifice may be provided fluidly in series between the fuel pump and the direct injection nozzle in order to attenuate noise resulting from fuel pump pulsation. A clip holder and clip plate mount the fuel injector to the injector cup.

    摘要: A fuel system component for a direct injection internal combustion engine. The component includes a fuel rail and a plurality of direct injection fuel injectors which are rigidly attached to the rail. Each fuel injector has an elongated body as well as a harness assembly extending laterally outward from the elongated body. Each injector is attached to the fuel rail such that, when viewed along an axis of the fuel injector body, the fuel rail overlies at least a portion of the injector body and at least a portion of the harness assembly.
