摘要

The present invention relates to a semi-closed cycle internal combustion prime mover, comprising: a compression device (5); a volumetric expander (6) distinct from the compression device (5); first feeding devices (23) connected to the volumetric expander (6) and configured to feed a fuel into the volumetric expander (6) and/or second feeding devices (24) connected to the volumetric expander (6) and configured to feed an oxidant into the volumetric expander (6). The volumetric expander (6) is configured to perform a combustion with a pressure increase and an expansion, but not a compression of the working fluid. A closed circuit (12), in which at least a working fluid circulates, connects the compression device (5) and the volumetric expander (6) to each other. A recuperator (25) is disposed in the closed circuit (12) and is operatively interposed between the compression device (5) and the volumetric expander (6). The recuperator (25) is configured to transfer heat from the working fluid coming from the volumetric expander (6) and directed towards the compression device (5) to the working fluid coming from the compression device (5) and directed into the volumetric expander (6).
