PISTON ASSEMBLY FOR A RECIPROCATING ENGINE

摘要

According to the present invention, a power cylinder system for a reciprocating engine includes a steel piston configured to move within a cylinder of the reciprocating engine. The system also includes a groove circumferentially extending about the piston beneath a top land of the piston and configured to support a ring having an inner circumferential surface. One or more channels are formed at the top land and are configured to facilitate transfer of combustion gas to a space between a portion of the groove and the inner circumferential surface of the ring.
