<p>A Rankine cycle device of an internal combustion engine, comprising an evaporator (3) for generating steam, an expansion machine (4) for converting the heat energy of the steam into a mechanical energy, a condenser (5) for changing the steam discharged from the expansion machine (4) into water by cooling, a tank (6) for storing the water from the condenser (5), and feed pumps (7, 8) for pressurizing and feeding the water inside the tank (6) to the evaporator (3), wherein the water inside the tank (6) is fed, by a low-pressure pump (7), to a distributing valve (106) through the water jacket (105) of the internal combustion engine (1), a part of the water distributed by the distributing valve (106) is further pressurized by the high-pressure pump (8) and fed to the evaporator (3), and the remaining water distributed by the distributing valve (106) is discharged to the tank (6) after radiating a heat in an auxiliary equipment (110) such as a heater for cabin heating, whereby, a radiator can be abolished by allowing the heating part of the internal combustion engine (1) to be sufficiently cooled by water as the liquid phase working medium of the device while maintaining the performance of the Rankine cycle device.</p> |
