  • Publication number: 20100301601
    Abstract: A fluid coupling for a fuel system in a direct injection internal combustion engine having a body with a ball portion and a fluid passageway extending through the ball portion. The body also includes external threads which extend concentrically around the ball. A tube has an outwardly flared end while both a ferrule and a nut are disposed over the tube. The nut includes internal threads which threadably engage the external threads on the body so that, upon tightening, the nut compresses the outwardly flared portion of the tube in between the ferrule and the ball thus sealingly coupling the tube to the body in fluid communication with the passageway formed through the ball.

  • Patent number: 7527038
    Abstract: 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.

  • Patent number: 7093426
    Abstract: To improve startability and reduce the amount of HC emission at start-up with the aid of a construction where vaporized fuel is supplied to the bypass passage that bypasses the main passage. The main air control valve 16 is installed near the intake port 10 of the main air passage 3, and the main air control valve is closed or throttled at the time of start-up or additional injection from the port injection valve 5 is given in the beginning of start-up cranking. With a apparatus equipped with the main air control valve, vaporization of the fuel injected from the auxiliary injection valve 6 is facilitated in the beginning of cranking and also intake delay of the vaporized fuel is reduced, and hence startability can improve and the amount of HC emission at the time of start-up can decrease.
