Abstract: A valve assembly includes a valve body defining a cylindrical passage therein about an axis. An inlet port is defined in or near a first end of the valve body. First and second outlet ports are defined in the valve body extending radially outward from the cylindrical passage. A cylindrical valve spool having a central passage is positioned within, and sealingly engaged with, the cylindrical passage. The valve spool is moveable along the axis among: a first position wherein the inlet port is in fluid communication with the first outlet port but not the second outlet port, a second position wherein the inlet port is in fluid communication with the second outlet port but not the first outlet port, and an intermediate position between the first and second positions wherein the inlet port is in fluid communication with both of the first and second outlet ports.

Abstract: In an engine piston assembly of the present invention, a piston structure, together with a piston ring set matched to the piston structure and an inner wall of a cylinder bore body, forms a crevice passage having at least two annular expansion chambers and also having a function of multistage throttling and expansion. The engine piston assembly of the present invention can not only greatly and effectively reduce the intra-cylinder carbon deposition and the hydrocarbon emissions in the exhaust gas emissions of the engine, but also significantly improve the engine efficiency and the overall performance of the engine, so that the present invention is suitable for wide applications.

Abstract: The present invention discloses an energy-saving and emission-reducing multistage throttling expansion method for engine. In a crevice passage disposed between the combustion chamber and the crankcase, a multistage throttling is disposed for converting pressure energy of the high-pressure blow-by gas into kinetic energy and momentum, and a multistage expansion is disposed for expanding and dissipating the incoming kinetic energy and momentum of the high-velocity blow-by gas into heat, so that to realize the multistage throttling and expansion method, reduce the leaking of the unburned fuel-air mixture and the burned gas, the hydrocarbon emissions hidden in the intra-cylinder carbon deposition and exhaust gas emissions of the engine, and also improve the engine efficiency and the overall performance of the engine.

Abstract: A piston ring is formed from a ring blank, e.g., a wire, that has a cross sectional profile including upper and lower surfaces that are generally parallel and disposed between inner and outer peripheral faces. The cross sectional profile also includes a hook area at the outer portion of the lower surface that includes a nose area. The nose area is provided with a radius that is as sharp as possible, and is disposed such that a grinding operation performed on the lower surface, e.g., with a single generally planar grinding surface, will also grind the nose area, thereby truncating the nose area and increasing sharpness of the nose area without having to perform additional machining operations.

Abstract: A material for use as a centering device for centering a ring within a groove of a piston when the ring is in an uncompressed free state is manufactured from a mixture of approximately eighty (80) parts by mass petrolatum with approximately twenty (20) parts by mass carnauba wax based on one hundred (100) parts by mass of the mixture. The petrolatum and the carnauba wax are heated to a liquid state and then combined to form the mixture. Once combined, the mixture is maintained in a liquid state for a pre-defined period of time, after which the mixture is cooled to room temperature to form a block of the mixture. Once cooled, layers of the mixture are scraped from the block. Each layer includes a maximum layer thickness equal to or less than 2.5 mm.
