In multi-cylinder opposed engine constructions provision of lubricant for lubricating bearings, for cooling cylinders, and for cooling pistons includes pumping an inlet stream of lubricant through a gallery in the engine that is in fluid communication with bearing lubricant passages and cylinder coolant passages and providing lubricant from the inlet stream of lubricant into at least one piston coolant manifold in response to a first engine operating condition.

Opposed piston engines with controlled provision of lubricant for lubrication and cooling

Integrated, multi-cylinder opposed engine constructions include a unitary support structure to which cylinder liners are removeably mounted and sealed and on which crankshafts are rotatably supported. The engine constructions include a cooled piston with a resiliently deformable joint connecting crown and skirt and a cooled cylinder liner with wipers to manage lubricant in the cylindrical interstice between the cylinder bore and the piston skirts.

Cylinder and piston assemblies for opposed piston engines

Integrated, multi-cylinder opposed engine constructions include a unitary support structure to which cylinder liners are removeably mounted and sealed and on which crankshafts are rotatably supported. The unitary support structure includes cooling manifolds that provide liquid coolant to the cylinder liners. Exhaust and intake manifolds attached to the support structure to serve respective ports in the cylinder liner. The engine constructions may also include certain improvements in the construction of cooled pistons with flexible skirts, and in the construction of cylinders with sealing structures mounted outside of exhaust and inlet ports to control lubricant in the cylindrical interstice between the through bore and the pistons.
