摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： The invention relates to a coolable annular support (1) for internally cooled piston rings, comprising an annular body (2) embodied as a circular ring and a cooling channel plate (3), the cooling channel plate (3) being a component of the cooling channel, and a method for the production thereof. The components forming the annular body (2) and the cooling channel plate (3) are connected together by means of laser beams from at least one laser in a continuous wave operation. The cooling channel plate (3) is U-shaped and has openings (6) which act as an inlet or an outlet for the cooling material in conjunction with tubular-shaped bodies. It is possible to simultaneously compensate variations in volume by different air temperatures during welding. At least one edge of the annular body (2) and the cooling channel plate form a cavity (5) for the cooling material by connecting the end areas of the limbs of the cooling channel plate to said edge of the annular body (2). The connections of the annular body (2) and the cooling channel plate (3) takes place by means of one or more overlapping weld seams (4), so that a sealing connection between said two components is guaranteed.
