摘要： A lubricating configuration in a two-stroke cycle, opposed-piston engine for a piston wristpin minimizes losses in oil pressure at the wristpin as the piston approaches bottom center and reduces the required oil supply pressure to the engine. The wristpin is constructed to absorb and store oil pressure energy when oil pressure at the wristpin is high, and to release that stored energy to pressurize the oil at the wristpin when connecting rod oil pressure is low.

摘要： An opposed-piston engine has an air handling system equipped with a turbo-compound system that includes a power turbine for producing a rotary output in response to a flow of exhaust gas flowing into the turbine. The rotary output is connected to a crankshaft or other rotating element of the opposed-piston engine for converting some of the exhaust gas energy into mechanical energy supplied to the crankshaft.

摘要： A piston rolling thrust bearing construction is constituted of a pair of bearing plates with opposing faces disposed in a spaced alignment with a rolling ball assembly positioned between the opposing faces to support relative movement between the bearing plates. The piston rolling thrust bearing is mounted to the open end of the skirt of a piston disposed in a cylinder to compensate for non-axial motion relative to the cylinder axis due to the articulating motions of connecting elements or any structural misalignments within an engine drive train assembly.

摘要： A combustion chamber for an opposed-piston engine is defined between a pair of pistons disposed for opposing reciprocal movement in a cylinder. The combustion chamber is formed between crowns of the pistons and has a radius that decreases from the longitudinal axis of the cylinder. Each crown includes a periphery, a bowl within the periphery defining a concave surface with a first portion curving inwardly toward the interior of the piston and a second portion curving outwardly from the interior, and a convex surface within the periphery curving outwardly and meeting the second portion of the concave surface to form a ridge. Each ridge has a height that decreases with the distance from a longitudinal axis.

摘要： A cylinder cooling construction includes a cylinder liner with a sidewall, exhaust and intake ports opening through the sidewall, a bore, and a plurality of feed channels that are formed with and extend along the sidewall from a central band of the cylinder toward the exhaust and intake ports. A sleeve covering the sidewall includes a plurality of impingement jet ports that are arranged in at least one sequence extending around the central band and that are in liquid communication with the plurality of feed channels. An annular member disposed between the liner and the sleeve reinforces the central band. The sleeve further includes an inside surface with spaced-apart annular recesses that with the sidewall define liquid coolant reservoirs in the vicinity of the ports that are in liquid communication with the feed channels. Channels through bridges of exhaust port have first ends in liquid communication with the coolant reservoir in the vicinity of the exhaust port and second ends that open through a portion of an exhaust end of the cylinder.

摘要： In a two-cycle, opposed-piston internal combustion engine, opposed pistons disposed in a cylinder are coupled to a pair of side-mounted crankshafts by connecting rods that are subject to substantially tensile forces acting between the pistons and the crankshafts. This geometry reduces or eliminates side forces between the pistons and the bore of the cylinder. The cylinder and the pistons are independently cooled to reduce cylindrical deformation caused by thermal expansion during engine operation.
