FIELD: energetics.
SUBSTANCE: invention relates to power engineering. Heat engine based on Rankin organic cycle (ROC), contains a circuit for working fluid medium loop, which includes: evaporator for working fluid medium heating and evaporation; condenser for working fluid medium cooling and condensation and volumetric expander-generator with inlet communicated with evaporator by fluid medium, and outlet communicated with condenser by fluid medium, wherein heat engine based on ROC additionally comprises: control system connected with volumetric expander-generator containing switch and driving device, wherein switch is switching over between first and second states, wherein in first state switch is connected with driving device and volumetric expander-generator is driven by driving device, and in second state switch is not connected with driving device or driving device is disabled and volumetric expander-generator is not actuated by driving device.
EFFECT: higher efficiency of engine operation.
