A crankshaft driven positive displacement gear type air compressor enclosed within the engine housing forces air in between the compressor and reciprocating means. At approximately top dead center fuel is injected into the engine and burns. The high pressures of combustion transfer energy to the gears of the compressor and the reciprocating means and crankshaft assembly forcing them to accelerate. The reciprocating means accelerates to the bottom dead center position completely uncovering two exhaust ports. Exhaust passes through the exhaust ports and is scavenged with compressed air from the compressor flowing into the housing space enclosing the reciprocating means. The reciprocating means returns to the top dead center position compressing air in the housing space between the compressor and the reciprocating means. At approximately top dead center the process repeats itself.
In a two stroke internal combustion engine for the generation of useful rotational motion and torque having housing means for enclosing the necessary internal spaces within the engine, crankshaft means for the conversion of reciprocating motion into rotary motion and power output from the engine, reciprocating means for the transfer of energy created by combustion to the crankshaft and for compressing combustible material within the engine for combustion, fuel supply means for supplying fuel for combustion to the engine, air intake means for passing air for combustion into space within the housing, exhaust gas outlet means for passing exhaust gases out of space within the housing, the improvement comprising a crankshaft driven positive displacement gear type air compressor located within the engine housing to compress the air between the reciprocating means and the air compressor having power output shafts.
