PROBLEM TO BE SOLVED: To provide a new operating method of an internal combustion engine.SOLUTION: In the method, at least one turbine (3) is arranged in an internal combustion engine (1), and exhaust gas leaving the internal combustion engine (1) can be supplied to the turbine for expansion. Energy obtained at that time is used for driving at least one compressor (2) or at least one power generator, and at least one catalyst-type exhaust gas purification device (6) is arranged in the internal combustion engine (1), and the expanded exhaust gas can be supplied to the catalyst type exhaust gas purification device or each turbine (3) for cleaning. Or, to make a quick heating process of each catalyst type exhaust gas purification device (6) sure, an adjusting variable relating to influences of a waist gate, and/or an adjusting variable relating to influences of a turbine geometry of each turbine (3) are determined according to a temperature setting value relating to exhaust gas temperature existing before each turbine (3). |
