  • Patent number: 6840268
    Abstract: A high-pressure connector for a fuel injection system including an elongated body having an inlet that is in fluid communication with a source of high-pressure fuel, an outlet in fluid communication with the inlet of a fuel injector and a fuel passage extending therebetween. A filter is supported within the fuel passage and acts to filter particulates from the high-pressure fuel. A fuel flow limiter is supported within the fuel passage and is operable to provide predetermined quantities of fuel to pass between the inlet and the outlet at each injection event during normal operation of the combustion chamber serviced by the injector and to automatically terminate fuel flow through the connector in the event of a malfunction at the combustion chamber.
    Type: Grant

  • Patent number: 6520069
    Abstract: In a piston engine, end play of the piston pin can be prevented without unduly shortening the pin. In the simplest design (FIG. 4), a full length piston pin can have spherical end surface in close clearance spacing relative to the combustion chamber surface, so that any tendency of the pin to shift along the pin axis is immediately resisted by contact between a spherical end surface and the combustion chamber surface. The area of each spherical surface is sufficient to prevent wear or scratching of the combustion chamber surface. An alternative full length piston pin design incorporates spherical sheet-metal caps snapped in place at the ends (FIG. 2), which fix the pin (and caps) from coming into contact with the cylinder bore wall.

  • Patent number: 6016775
    Abstract: A two-cylinder head is provided for use in a narrow vee-type internal combustion engine. A vee-type internal combustion engine which includes at least one such two-cylinder head is also provided. The two-cylinder head includes a pair of liner flange counterbores which cover a pair of engine cylinders. The liner flange counterbores are staggered relative to, and overlap, a head centerline, and each include exhaust and intake ports which are a mirror image of each other. A respective exhaust passage extends from each exhaust port to the same exhaust manifold mounting face which extends at an angle relative to the head centerline.
