Abstract: A clamping assembly for clamping a fuel injector into a fuel injector bore located in cylinder head of an engine includes a housing having a housing opening, connectors coupling the housing to the cylinder head, and a compression spring. The compression spring is located in the housing opening, operably coupled to a top of the fuel injector, and axially aligned with a longitudinal axis of the fuel injector.

Abstract: A shaft damping device includes a damping ring having a splined bore, a shaft having at least one spline, and a fluid feed system. The shaft is disposed within the splined bore such that the splines of the shaft mesh with the splined bore, forming a damping space therebetween. The fluid feed system is operable to control a quantity of a fluid within the damping space.

Abstract: A variable flow venturi assembly for use in an exhaust gas recirculation system of an internal combustion engine having a housing with an inner chamber, a combustion air inlet in communication with the inner chamber, and an exhaust gas inlet in communication with the inner chamber. A venturi valve is slidably disposed within the chamber. A venturi valve has a longitudinally extending throughhole with an inlet opening in communication with the combustion air inlet, an outlet opening and a venturi section interposed and in communication with each of the inlet opening and the outlet opening. The venturi valve further has at least one bypass port and at least one induction port. Each bypass port is in communication with a combustion air inlet and a throughhole. Each induction port is in communication with the exhaust gas inlet and the throughhole. An actuator slidably moves the venturi valve within the inner chamber of the housing.

Abstract: Past pistons have been susceptible to reduced longevity due to increased forces of combustion thereon during operating cycles of an engine. The present two piece unitary piston increases the longevity of pistons used with increased forces of combustion. For example, a head member has a crown portion defining a ring band portion having a bottom surface and a support portion. And, a skirt member defines a ring band support surface and a mating portion. The head member and the skirt member have a preestablished material strength being generally the same. The head member and the skirt member are joined at an interface of the support portion and the mating portion by an interference fit and are joined at the interface of the bottom surface and the ring band support surface by a weld. The force of combustion acting on the crown portion is resisted by the ring band support surface being in contacting relationship with the bottom surface.

Abstract: A water-cooled engine exhaust manifold has an internal exhaust conduit or heat sheild comprised of a plurality of axially shiftable sections through which the hot exhaust gases pass from the engine to a hot gas turbocharger. A casing encircles the exhaust conduit and is held in spaced relationship to the exhaust conduit so as to provide dead air space or other insulating material space for insulating the hot exhaust gases from the casing. An outer shell encircles the casing and is sealed to exhaust inlet elbows and to fluid inlet flanges to provide a water jacket to cool the surface of the casing. The exhaust inlet elbows communicate with each different section of the exhaust conduit. Clearance is provided between the ends of each section of the exhaust conduit to permit expansion and axial shifting of the sections of the exhaust conduit without, in any way, interfering with the function and operation of the fluid-cooled jacket of the manifold.

Abstract: A resilient drive comprises rotary driving and driven members interconnected by a resilient coupling. The coupling comprises a pair of coil springs and a plurality of spherical balls abutting the springs in circumferentially disposed relationship therewith. A pressurized fluid, such as oil, is continuously communicated to the coupling to aid in the damping function thereof.
