摘要： An opposed-piston engine with a single crankshaft has a rocker-type linkage coupling the crankshaft to the pistons that utilizes a rotatable pivot rocker arm with full-contact plain bearings. A rocker-type linkage utilizes a rotatable pivot bearing with an eccentric aspect to vary translation of piston linkage along the axial direction of a cylinder, which shifts the top dead center (TDC) and bottom dead center (BDC) locations of a piston so as to change the volume of charge air compressed during the power stroke.

摘要： A piston construction for an opposed-piston engine accommodates contoured end surfaces of the piston crowns and articulation of the pistons with piston rods. The shape of each piston crown includes a bowl with an adjoining ridge that protrudes axially of the piston. A cooling construction for the piston includes an outer gallery running around the inner surface of the piston sidewall in the vicinity of the crown. The outer gallery girds and is in fluid communication with a central gallery that abuts the deepest part of the bowl. The outer gallery has an asymmetric profile that rises under the ridge and that slants upwardly under a peripheral portion of the bowl. A mechanism for coupling the piston to a piston rod includes a biaxial slipper bearing.

摘要： A combustion chamber for an opposed-piston engine includes a squish zone defined between circumferential peripheral areas of opposing end surfaces of the pistons, a cavity defined by one or more bowls in the end surfaces, and at least one injection port that extends radially through the squish zone into the cavity. The cavity has a cross-sectional shape that imposes a tumbling motion on air flowing from the squish zone into the cavity. Opposing spray patterns of fuel are injected into the combustion chamber. In some aspects, the opposing spray patterns are injected along a major axis of the combustion chamber.

摘要： A piston coupled to a crankshaft via pullrods presents challenges for coupling the piston to the crankshaft because the connections are provided outside the piston. A bridge is coupled to a piston skirt at the end of the piston away from the piston crown. The bridge structure includes: a central support structure, a first projection extending outwardly from the central support structure in a first radial direction, and a second projection extending outwardly from the central support structure in a second radial direction. The central support structure is substantially hollow with a series of internal braces to yield a lightweight piston.

摘要： A combustion chamber in an opposed-piston, internal-combustion engine is disclosed in which the pistons tops are designed so that when they approach each other, they induce a tumble flow in one or two hemispherical spaces defined in the piston tops. The combustion chamber further includes injectors side mounted in the cylinder wall. In one embodiment, the tumble flows in the two hemispheres are in the same direction and in another embodiment, in opposite directions. In yet another embodiment, there is only one injector and one hemisphere in which a tumble flow is induced.

摘要： Ported engines with opposed pistons are coupled to a single crankshaft through rocker arm linkages. Each pair of opposed pistons is coupled to a single crankpin of the crankshaft. Each piston is coupled to a respective rocker arm linkage by a rolling thrust bearing which prevents linkage movement that is transverse to the axis of the piston from being transferred to the piston. Each piston of a pair of opposed pistons is coupled to the same crankpin by respective rocker arm linkages in which connecting rods run between the crankpin and respective rocker arms. One connecting rod is connected to first rocker arm below the rocker arm's pivot point and another connecting rod is connected to a second rocker arm above the rocker arm's pivot point.
