초록

An exhaust valve assembly of an internal combustion engine selectively covers an exhaust manifold circumferentially located about a top wall of a cylinder without interfering with segments of a piston. The exhaust valve assembly includes a ring-shaped portion of a cylinder lining which is configured to selectively obstruct air from escaping radially from the top of the cylinder. An intake valve assembly is provided on a cylinder head and has a ring or washer shape. The timing of both valves is facilitated by a single spring and induction and exhaust gear...
