ABSTRACT:
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 cylinder so that a fuel rich mixture, when ignited in the combustion chamber, mixes with and burns air compressed in the power cylinder. 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.
