US 11,939,927 B2 · Internal combustion engine with oxygen concentrating equipment, method, program product and computer-readable medium for operating internal combustion engine with oxygen concentrating equipment

Abstract

The solution of the invention is an internal combustion engine with oxygen concentrating equipment (80) wherein the air taken in the cylinder space (15) during the intake stroke and pushed out by the piston (5) during the charging stroke charges one or more cells (41A-41Z, 51A-51Z) of the oxygen concentrating equipment (80) and after separating most of the nitrogen in the cells (41A-41Z, 51A-51Z), the oxygen rich air is injected into the cylinder space (15) through a compressor (33) at the beginning of the expansion stroke by an injector (11). The fuel is also introduced into the cylinder space (15) at the beginning of the expansion stroke by a fuel injector (19). The ignition may be spark ignition, self-ignition or their combination.
