<p>An engine is shown as having a ring-like cylinder with a ring type piston reciprocatingly received therein, connecting rods operatively interconnect the ring piston to a related crankshaft; the combustion chamber means is formed generally by two chamber volumes the first of which is defined by the annular space between the working surface of the ring piston and the juxtaposed cylinder head surface and the second of which is defined by a generally medially or centrally formed chamber of unexpandable volume; the two chamber volumes communicate with each other as by a relatively narrow opening formed generally peripherally about the chamber of unexpandable volume.</p> |
