PROBLEM TO BE SOLVED: To provide a method and apparatus for controlling the volume of air or a mixture of air and non-combusted fuel inside a combustion chamber and cylinder of an internal combustion engine.SOLUTION: The apparatus comprises an inlet-outlet port (9) connected to a supply source of air or air-fuel mixture, and having an opened state and a closed state; and a combustion chamber (7) with reduced volume. The inlet-outlet port (9) is controlled, when opened, to permit air or an air-fuel mixture to enter or enter and exit the combustion chamber (7) and a cylinder (3), and, when closed, to prevent air or an air-fuel mixture from entering or exiting the combustion chamber (7) and cylinder (3). The volume of air or air-fuel mixture located inside the combustion chamber (7) and cylinder (3), when the inlet-outlet port (9) closes, is less than the volume of the combustion chamber (7) and cylinder (3) defined when the inlet-outlet port (9) is closed and when a piston (1) is at the bottom dead center position inside the cylinder (3). |
