Abstract
A Rankine circuit () includes, as a plurality of heat exchangers, an EGR cooler () of an EGR circuit and an exhaust gas heat exchanger () associated with an exhaust passage. The EGR cooler and the exhaust gas heat exchanger are arranged such that the EGR cooler is located upstream of the exhaust gas heat exchanger as viewed in the flowing direction of a working fluid in the Rankine circuit. The amount of heat transferred from EGR gas to the working fluid in the EGR cooler is controlled by a control unit () so that the temperature of the EGR gas detected by an EGR gas temperature detector () may fall within a predetermined temperature range (e.g., 150° C. to 200° C.).
