    Abstract: A combustion chamber construction for opposed-piston engines includes an elongated, bilaterally symmetrical shape referenced to a major axis and a pair of injection ports located on the major axis when the pistons are near respective top center positions. The combustion chamber is defined between a bowl in the end surface of a first piston of a pair of pistons and mirrored ridges protruding from the end surface of a second piston of the pair. Each ridge includes a central portion that curves toward a periphery of the end surface of the second piston and which transitions to flanking portions that curve away from the periphery. The ridge configuration imparts a substantially spherical configuration to a central portion of the combustion chamber where swirling motion of charge air is conserved.

    Abstract: A compression-ignited, opposed-piston engine equipped for multi-fuel operation includes at least one cylinder, a pair of pistons slidably disposed in the cylinder for opposing movement between respective bottom and fop center locations, and spaced-apart intake and exhaust ports near respective ends of the cylinder. The pistons include end surfaces constructed to form a shaped combustion chamber when the pistons are near top center locations during a compression stroke of the engine. At least one gaseous fuel injector communicates with the bore of the cylinder through an injector site in the cylinder between the intake port and the exhaust port. At least one liquid fuel injector communicates with the bore through an injector site in the cylinder. A fuel injection system coupled to the at least one gaseous fuel injector and to the at least one liquid fuel injector is operable to cause the at least one gaseous fuel injector to inject a main charge of gaseous fuel when the pistons are between the bottom and top center locations and to cause the at least one liquid fuel injector to inject a pilot charge of liquid fuel.

    Abstract: 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 bow! 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 thai decreases with the distance from a longitudinal axis.

    Abstract: 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.
