1. Method for operating internal combustion engine including a system bounded by at least one cylinder wall (1), piston (5) and cylinder head (17), comprising the steps of:
(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 an 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 an 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 a fuel injector (19).
