Abstract
A power cylinder system for a reciprocating engine includes a piston configured to be disposed within a cylinder and to move in a reciprocating manner within the cylinder. The piston also includes a top-most groove extending circumferentially about the piston beneath a top land of the piston and a ring disposed within the top-most groove. A single channel is formed in the top land or the ring, and the single channel extends from an outer perimeter of the piston to a space between an inner surface of the top-most groove and an inner face of the ring.
