摘要： A HCCI engine includes a cylinder block with a cylinder head closing off a cylinder, a power piston slidably contained within the cylinder, and a boost piston for initiating timed combustion of fuel within a combustion chamber. The boost piston is housed within a wall of the combustion chamber such that when the boost piston moves from a base position to an extended position, the heat increase within the combustion chamber is sufficient to cause fuel within the combustion chamber to ignite.

摘要： A pressure-wave supercharger for an internal combustion engine is incorporated into the engine flywheel. The supercharger includes a rotor with a plurality of cells extending axially of the rotor and arranged circumferentially about the rotor, an exhaust tube for introducing exhaust gas into the cells at one end of the rotor during rotation thereof, an ambient air inlet tube for introducing air into the cells at another end of the rotor during rotation thereof, the air introduced into the cells being compressed by the exhaust gas introduced into the cells. A compressed air inlet tube feeds the compressed air to the engine. The cells or channels of the rotor are formed within the flywheel itself such that the flywheel operates as the supercharger mechanism.

摘要： A cylinder head and spark plug assembly for mounting on an engine block to create a combustion chamber for burning fuel and method for assembling the same are disclosed. A cylinder head has an end wall with an exterior surface and an interior surface and a spark plug bore extending downstream from the exterior surface to the interior surface. The spark plug bore has a seal surface adjacent the interior surface and external threads disposed upstream from the seal surface. A spark plug includes a body terminating in an end portion having a seal surface thereon, a nut and external threads disposed between the nut and the seal surface. The external threads of the spark plug are threadedly retained within the internal threads of the spark plug bore with the spark plug seal surface cooperating with the cylinder head seal surface in an interference fit eliminating any crevice between the end portion of the body and the spark plug bore downstream of the interference fit. Therefore, combustible fuels cannot reside in crevices between the body and the bore and escape being ignited during fuel burning in the combustion chamber.

摘要： An apparatus for ultrasonically welding workpieces that reduces sonotrode adhesion during the ultrasonic welding process. The sonotrode tip has a specific surface configuration, including a curvilinear shaped outer surface combined with a plurality of grooves and lands. Due to the curvilinear surface, the depth of the grooves gradually decreases near the outer edge or periphery of a contact surface of the sonotrode tip. Further, such a groove and land combination also provides a sharp edge or corner that reduces sliding of the tip on the workpiece and correspondingly reduces sticking. In addition, various types of coatings or inserts may also be used to reduce sticking of the sonotrode tip to the workpiece.

摘要： Method of making valve seats by thermally spraying bulk material. The method includes the steps of: (i) preparing a cylindrical polymeric mandrel having an outside dimension not greater than the desired inside dimension of the desired insert, the mandrel having no means to provide for separation of the sprayed material from the mandrel, (ii) thermal spraying separate particles of one or more types of steel or nickel alloys in the presence of a controlled oxidizing medium under conditions that allow firstly, melting of the mandrel and its infiltration into the sprayed material and secondly to form a subsequent polymer free dense metallic bulk composite material (iii) after cooling, machining and cutting into discrete seat shapes for implanting into the final product.
