摘要： The present invention relates to a Rankine system comprising a valve including a valve member. The valve member is provided with a valve controlling element in the form of an elongated tapered end portion with a tip end facing the duct, wherein the tapered end portion is arranged to be inserted through the opening and into the duct as the valve member is moved towards the valve seat. The actuator is configured to hold the valve member in at least one intermediate position between the first and second end positions, where the tapered end portion occupies a portion of a cross-sectional fluid through-flow area defined by the duct so as to partly restrict a flow of fluid through the duct.

摘要： A vehicle includes a pump, an evaporator, and an expander in sequential fluid communication in a closed loop containing a condenser configured to transfer heat between a working fluid and ambient air. The vehicle has a generator driven by the expander. The evaporator is configured to transfer heat from at least one of an engine coolant, a battery coolant, an engine lubricant, a transmission lubricant, an exhaust gas in an exhaust system, and an exhaust gas in an exhaust gas recirculation (EGR) system to the working fluid.

摘要： An internal combustion engine heat energy recovery system (1) comprises a first heat exchanger (20) arranged in heat communication with at least one heat energy source of an internal combustion engine (10) and with a working fluid of the system (1) for the transfer of heat energy from the heat energy source to the working fluid of the system (1). A turbine (30) is arranged in fluid communication with the working fluid heated in the first heat exchanger (20) for the expansion of the working fluid to produce shaft power. A second heat exchanger (40) is arranged in heat communication with the expanded working fluid to remove waste heat therefrom and transfer it to an external source such as the atmosphere. A first compressor (50) is arranged in fluid communication with the working fluid exiting the heat exchanger for increasing the pressure of the cooled working fluid prior to its entry into the first heat exchanger (20). The working fluid of the system is a substantially supercritical fluid.

摘要： Apparatus for utilizing heat wasted from an engine includes: a Rankine cycle (31); a transmission mechanism that couples an output shaft of an expansion device (37) to a rotary shaft of an engine via an electromagnetic clutch (32) that can be engaged and disengaged; a passage (65) through which refrigerant exiting a heat exchanger (36) flows so as to bypass the expansion device (37); and a bypass valve (66) interposed in the passage. To stop the expansion device (37), the electromagnetic clutch (32) is switched from an engaged state to a disengaged state after switching the bypass valve (66) from a closed state to an open state. If the bypass valve (66) becomes stuck in the closed state, expansion device front-rear differential pressure limiting processing in which a front-rear differential pressure of the expansion device is limited while maintaining the electromagnetic clutch (32) in the engaged state is performed.

摘要： A device for utilizing waste heat from an engine, which is provided with a Rankine cycle device having an expander bypass passage and a bypass valve that opens and closes the expander bypass passage, and transmits the output torque Tr of the Rankine cycle device to the engine, estimates the output torque Tr of the Rankine cycle device accurately. An output calculation part includes a torque estimation portion that estimates the torque of an expander. The torque estimation portion has a first torque estimation equation corresponding to an opening position of a bypass valve, and a second torque estimation equation corresponding to a closed position of the bypass valve. The output calculation part calculates an output torque Tr of a Rankine cycle device, based on a torque estimated value by the first or second torque estimation equation.

摘要： A system of recycling exhaust heat from an internal combustion engine may include an EGR line circulating a portion of exhaust gas generated from the engine to an intake side, a working fluid circulating line configured to have a working fluid satisfying a Rankine cycle, which is circulated therein, and an EGR side heat exchanging unit configured to perform a heat-exchange between an EGR gas flowing in the EGR line and the working fluid flowing in the working fluid circulating line. When a temperature of the EGR gas is equal to or greater than a reference temperature T1, the EGR gas is circulated to the intake side via the EGR side heat exchanging unit, and when the temperature of the EGR gas is less than the reference temperature T1, the EGR gas is circulated to the intake side without passing through the EGR side heat exchanging unit.
