<p>A multi-cylinder two-cycle engine has cylinders (17) disposed about and parallel to a power output shaft (13). Each cylinder (17) contains a pair of double-ended pistons which reciprocate towards and away from each other, piston motion being transferred to the power output shaft (13) through a pair of wobble plates (12). The inner ends (2) of the pistons control inlet ports (6) and exhaust ports (7) in a common combustion space (1). The outer ends (3) of the pistons act as pumping pistons in compression spaces (4) formed at the outer ends of the cylinders (17). Charging air is drawn into compression spaces (4) through inlet valves (11), compressed and transferred to the combustion space (1) via transfer ducts (5) and inlet ports (6). The air is further compressed in the combustion space by inward movement of the pistons, fuel injection and ignition then following. As the pistons are forced apart under the influence of combustion gas pressure, exhaust ports (7) and inlet ports (16) are exposed. Exhaust gases are purged by some part of the fresh incoming charge for further combustion in the exhaust chamber (9) and catalytic reactor (10).</p> |
