<p>In a valve in head two-cycle internal combustion engine, a slave piston and a power piston reciprocate in a pair of parallel cylinders. Valve opened and closed intake and exhaust ports respectively communicate with the slave piston and power piston cylinders. The engine head centrally contains a combustion chamber overlying a portion of both cylinders and communicating therewith through a valve opened and closed combustion inlet port and a combustion outlet port respectively communicating with the slave cylinder and power cylinders so that a fuel rich mixture, when ignited in the combustion chamber, mixes with and burns air compressed in the power cylinder. A blower forces burned gases through the exhaust port when the power piston uncovers lateral ports in the power cylinder wall at the end of the power stroke. An engine head supported rocker arm and shaft assembly, driven by a cam shaft, opens and closes the valves in sequence with the reciprocating pistons.</p> |
