Six cycle combustion and fluid vaporization engine
A reciprocating piston engine is described of the type including a piston reciprocal in a cylinder toward and away from an expansion chamber at one end of the cylinder and also provided with intake and exhaust valves openable and closable in timed sequence with reciprocation of the piston. The valves are closed during the compression and power strokes of the piston, and the exhaust valve is opened during the third stroke of the piston toward the expansion chamber. During the fourth stroke of the piston, a readily vaporizable liquid is injected into the expansion chamber under pressure for flashing into a vapor upon being heated by the residue heat of combustion in the expansion chamber, and during the fifth and sixth strokes of the piston the exhaust and intake valves, respectively, are open to exhaust the vaporized liquid therefrom and intake a fresh combustible mixture of air and fuel into the expansion chamber and cylinder prior to compression of the mixture on the next stroke of the piston toward the expansion chamber. Also, the expansion chamber and piston include a plurality of fin portions for absorbing considerable quantities of heat during the combustion power stroke and the combustion gas exhaust stroke of the engine whereby sufficient residue of heat is retained within the combustion chamber for substantially instantly flashing the vaporizable liquid injected thereinto during the fourth stroke of the piston into a vapor.
