An internal combustion engine plant comprises a water-cooled internal combustion engine (1), at least one supercharging unit (3,8) the air charge conduit (6) of which includes an air cooler heat exchanger (7), a first vapour circuit (13) arranged to operate at a higher pressure and temperature level and to extract, in a heat exchanger 12, waste heat from the exhaust gases of the engine, and a second vapour circuit (25) arranged to operate at a lower pressure and temperature level and to extract, in heat exchanger 7, heat from the air charge and to extract waste heat from the cooling water of the engine, in heat exchanger 22. Working medium from the two vapour circuits is fed to a vapour turbine (32) for expansion to perform work, the cooling water circuit of the internal combustion engine being arranged as a hot-water circuit (21, 22, 23, 24) at positive pressure e.g. 5 atmospheres and with cooling water temperatures in excess of 100 DEG C, e.g. 130 DEG C, in which the second vapour circuit for the evaporation of the working medium in that circuit includes a heat exchanger (28) disposed in the heat exchanger 7 for heating the working medium in a liquid state, an expansion device (31) for vapour generation, and a chamber (34) in which vapour and liquid are separated. <IMAGE> |
