De′ sax′ e two cycle engine, constant pressure adiabatic compound “C.P.A.C.”

A reversible heat, constant pressure two-cycle engine comprising:

• at least one cylinder having a combustion chamber with a top opening and at least one exhaust port located remotely from said top opening;
• a piston movable within said at least one cylinder, having a top surface, and being configured and dimensioned for revealing said at least one exhaust port at the end of a power stroke;
• an igniter communicating with said top opening;
• a fuel delivery system positioned between said top opening and said igniter;
• a venturi also positioned between said top opening and said igniter, said venturi being configured so that hot air compressed by said piston and forced to travel through said venturi toward said igniter educts fuel from said fuel delivery system;
• a blower assembly configured for providing hot air into said at least one cylinder;
• and
• an air intake valve positioned between said blower assembly and said combustion chamber, said air intake valve being incapable of softening after heating and configured for opening and closing as a result of pressure differential, whereby when said air intake valve is closed, hot compressed induction air is forced by said piston into said venturi, the velocity of the hot air educts fuel from said fuel delivery system and drives the combustible fuel-air mixture to said igniter, where the fuel-air mixture flow changes from laminar to turbulent and ignition occurs, after which the combustible mixture expands into said combustion chamber, is leaned with the air in said combustion chamber, expands with great pressure rise, and is forced onto said top surface of said piston producing a power stroke, the lean burn also permitting the complete burning of the fuel to eliminate emissions from said exhaust ports, the exhaust gases exit said ports at velocity and create the pressure decay in said at least one cylinder that is responsible for opening said air intake valve to allow fresh air to again enter said at least one cylinder for the next power stroke.

A method for manufacturing a reversible heat, constant pressure two-cycle engine, said method comprising the steps of:

• providing at least one cylinder with at least one upper air intake opening, at least one lower exhaust opening, and a top air compression opening,
• also providing a piston, an igniters, a fuel delivery system, a venturi, a blower assembly, and an air intake valves for use with said at least one cylinder;
• pairing said piston said at least one cylinder so that said piston is movable within said at least one cylinder;
• associating said igniter said at least one cylinder so that said igniter communicates with said top air compression opening;
• associating said fuel delivery system and said venturi with said at least one cylinder so that said fuel delivery system and said venturi both communicate with said top air compression opening and said igniter, and further so that said venturi is positioned to allow compressed air passing through said top air compression opening to educt fuel from said fuel delivery system;
• positioning said blower assembly in fluid communication with said at least one upper air intake opening of said at least one cylinder;
• and
• positioning said air intake valve between said blower assembly and said at least one cylinder so that said air intake valve is movable between an open position that allows hot air flow through said at least one air intake opening and a closed position that prevents hot air flow through said at least one air intake opening, and further wherein said air intake valve is adapted for opening and closing as a result of pressure differential;
• whereby when said air intake valve is closed, hot compressed induction air within said at least one cylinder is forced by said piston into said venturi, the velocity of the hot air passing through said venturi educts fuel from said fuel delivery system and drives the fuel-air mixture to said igniter where the fuel-air mixture flow changes from laminar to turbulent and ignition occurs, after which the fuel-air mixture expands into said at least one cylinder, is leaned with the air therein, expands with great pressure rise, and is forced onto the top of said piston producing a power stroke, the lean burn also permitting the complete burning of the fuel to eliminate emissions in the exhaust leaving said at least one cylinder through said at least one lower exhaust opening, the exhaust gases exiting said at least one cylinder at velocity creating the pressure drop that is responsible for opening said air intake valve to allow a fresh charge of hot air to again enter said at least one cylinder for the next power stroke.
