International Classification:

F02B 75/18

US Classification:

123 522, 123 51 R, 123 4181, 123 4183, 123 4184

Abstract:

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.

US Classification:

606052, 12356814, 123 51 B, 123 46 R

Abstract:

A two-stroke, opposed-piston engine with one or more ported cylinders and uniflow scavenging includes an exhaust gas recirculation (EGR) construction that provides a portion of the exhaust gasses produced by the engine for mixture with charge air to control the production of NOx during combustion.

US Classification:

123 51R, 123 522, 123 4181, 123 4183, 123 4184

Abstract:

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.

Assignee:

Achates Power, Inc. - San Diego CA

International Classification:

F02F 3/22
F01P 3/06
F02B 75/28

US Classification:

123 4144, 123 51 R, 1231936

Abstract:

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.
