System and method of recording and reproducing wide band channel information by means of several narrow band channels

摘要

In a two-cycle internal combustion engine wherein the air inlet ports (40, 43) are opened and closed directly by the reciprocating movement of the piston (12), and the exhaust ports are controlled by mechanically operated valves (19), the crankshaft (24) is laterally offset from the central plane common to the longitudinal axes of all the cylinders (10). This results in a substantial increase in the power output of the engine.
