Summary: | The solution of the invention is an internal combustion engine having an oxygen concentration device (80), in which the air compressed in the compression stroke is not used for combustion but is removed from the cylinder space (15) and used for operating the oxygen concentration device (80). The essence of the invention is that, during each compression stroke of the engine, the cylinder space (15) is temporarily connected to one or more units of the oxygen concentration device (80). One or more units (41A-41Z, 51A-51Z) of the oxygen concentration device (80) are filled with air, which enters the cylinder space (15) during the intake stroke and is pushed out by the piston (5) during the compression stroke, and after a majority of the nitrogen gas in the units (41A-41Z, 51A-51Z) is separated, one or more of the units (41A-41Z, 51A-51Z) are separated. The oxygen-enriched air is injected by the injector (11) into the cylinder space (15) through the compressor (33) at the start of the expansion stroke. Fuel is als |
