Patent ID: 8001949

Claim:
A method of operation of an internal combustion engine, said method comprising the steps of: opening a sliding port of a compression chamber; moving a compression piston to create an area of low pressure therebehind which forces atmospheric air to enter into said compression chamber through air filters; covering an entire volume of said compression chamber with atmospheric air; closing said sliding port of said compression chamber thereby producing a volume of air between said sliding port and said compression piston; compressing said volume of air by continuing to move said compression piston; opening a compression chamber valve once a predetermined pressure has been reached and allowing said air to transfer from said compression chamber to a pressure chamber; storing said air in said pressure chamber; opening a combustion chamber valve allowing said air to transfer from said pressure chamber to said combustion chamber; moving a combustion piston to create an area of low pressure therebehind which favors air to enter into said combustion chamber from said pressure chamber; injecting fuel into said combustion chamber so as to mix with said air; closing said combustion chamber valve; igniting said air and fuel and producing an exhaust gas which expands and pushes said expansion piston in a motion that moves said engine shaft which moves said compression piston; and closing said compression chamber valve; wherein opening and closing of said sliding port, said compression chamber valve and said combustion chamber valve is controlled by at least one of an engine processor and a difference in pressure.
