Claim 12:
13. Internal combustion engine including a system bounded by at least one cylinder wall (1), piston (5) and cylinder head (17), an intake valve (7) and an exhaust valve (14) connected to the system bounded by at least one cylinder wall (1), piston (5) and cylinder head (17), characterized by that:
the system bounded by the cylinder wall (1), the piston (5) and the cylinder head (17) is operated by intake, charging, power and exhaust strokes,
a charging valve (9) is connected to the system bounded by at least one cylinder wall (1), piston (5) and cylinder head (17),
the output of the charging valve (9) is connected to the input (58) of an oxygen concentrating equipment (80) through a charging manifold (8),
a first output (30) of the oxygen concentrating equipment (80) is connected to the input of a compressor (33),
the output of the compressor (33) is connected to the input of an oxygen rich gas injector (11),
the output of the oxygen rich gas injector (11) is in the system bounded by at least one cylinder wall (1), piston (5) and cylinder head (17),
the output of a fuel injector (19) is in the system bounded by at least one cylinder wall (1), piston (5) and cylinder head (17),
a second output (42) of the oxygen concentrating equipment (80) is connected to the input of a vacuum pump (38),
the output of the vacuum pump (38) is in open atmosphere, the oxygen rich gas injector (11) and the fuel injector (19) are operated by a control module (50) the control module configured to execute:
(a) operating the system bounded by the cylinder wall (1), the piston (5) and the cylinder head (17) by intake, charging, power and exhaust strokes,
(b) pushing out the gas by the piston (5) from the system bounded by the cylinder wall (1), the piston (5) and the cylinder head (17) during every charging stroke to operate the oxygen concentrating equipment (80),
(c) injecting oxygen rich gas extracted by the oxygen concentrating equipment (80) to the system bounded by the cylinder wall (1), the piston (5) and the cylinder head (17) through a compressor (33) by the oxygen rich gas injector (11),
(d) injecting fuel to the system bounded by the cylinder wall (1), the piston (5) and the cylinder head (17) by the fuel injector (19).
