Abstract:
An internal combustion engine designed to operate on a six-stroke cycle, said internal combustion engine comprising:a) at least one piston and cylinder assembly including a piston reciprocally mounted within a cylinder and intake and exhaust valves cooperatively mounted to regulate fluid flow into and out of said cylinder and an ignition source structured to ignite a combustible mixture within said cylinder, b) a central processor responsive to energy content within said cylinder at least during a first predetermined portion of the six-stroke cycle and operatively connected to an injection assembly, c) said injection assembly disposed and structured to inject a quantity of water into said cylinder during a second predetermined portion of the six-stroke cycle based at least in part on said energy content, d) a first intake stroke wherein said inlet and exhaust valves are respectively opened and closed and during which a combustible fluid enters said cylinder, e) a second compression stroke and a third power stroke wherein said inlet and exhaust valves are closed and during which said combustible fluid is respectively compressed and ignited, f) a fourth compression stroke wherein said intake and exhaust valves are closed and during which water is injected into said cylinder and the water and ignited fluid are compressed, g) a fifth power stroke wherein said intake an exhaust valves are closed and during which the injected water converts to steam, h) a sixth stroke wherein said intake and exhaust valves are respectively closed and opened and during which the steam and ignited fluid are exhausted, and i) said first predetermined portion of the six-stroke cycle comprising a portion of said third stroke and said second predetermined portion of said six-stroke cycle comprising an end of said third stroke and at least a portion of the duration of said fourth stroke.
