Abstract
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.
