    摘要: A Rankine circuit (40) includes, as a plurality of heat exchangers, an EGR cooler (36) of an EGR circuit and an exhaust gas heat exchanger (41) 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 (60) so that the temperature of the EGR gas detected by an EGR gas temperature detector (39) may fall within a predetermined temperature range (e.g., 150° C. to 200° C.)

    摘要: A waste heat recovery system of an internal combustion engine, in which regenerative energy transmitted to the internal combustion engine is increased with a simple mechanism. A controller of the waste heat recovery system of an internal combustion engine makes a determination as to whether it is necessary to increase the pressure of heat-transfer media in a heat exchanger, on the basis of the pressure detected by the high-pressure sensor. When it is necessary to increase the pressure in the heat exchanger, the controller causes a flow-rate regulating valve to start regulating the flow rate of the heat-transfer media while leaving the pump working. The controller causes the flow-rate regulating valve to continue the regulation at least until it is not necessary to increase the pressure in the heat exchanger, and then terminates the regulation.

    摘要: Control means (32) that controls the actuation of Rankine cycle (8) is provided. An evaporator (10) is capable of absorbing heat from the waste heat of the internal combustion engine (4) with an upper limit of preset maximum heat absorption amount and transferring the heat to working fluid. The control means (32) controls the flow rate of the working fluid so that the working fluid evaporated by the evaporator (10) comes into a superheated state in a heater (18), when the working fluid enters the evaporator (10) at a flow rate equal to or lower than preset flow rate at which the working fluid can absorb the preset maximum heat absorption amount of heat, and controls the flow rate of the working fluid so that the working fluid that overflows the evaporator (10) is evaporated by the heater (18) and then comes into the superheat state, when the working fluid enters the evaporator (10) at a flow rate higher than the preset flow rate.
