摘要： Although internal combustion engines typically waste about 75% of their fuel energy, this invention can provides 31% or more brake horsepower than the engine alone by using anhydrous organic racing engine coolant or other anhydrous organic heat transfer fluid arranged to spiral around a combustion chamber until heated to over 250° C. without boiling while exceeding the boiling point of a separate working fluid that is heated by coolant then superheated by exhaust gas before entering a unique positive displacement vapor expander engine having a piston connected by a clutch to a driveshaft that is also driven by the combustion engine to create a high efficiency direct mechanical powertrain which avoids losses of about 15% had a generator charged a battery powering an electric motor-generator connected for regenerative braking to charge batteries. Highly elevated coolant temperatures also reduce cylinder and exhaust temperatures to lower emission toxicity while preventing lubricant burnout.

摘要： The disclosure concerns a waste heat recovery system that is configured to operate as a prime mover in emergency case, when the heat source is down. The waste heat recovery system comprises, in addition to a heater configured to circulate a working fluid in heat exchange relationship with a heating fluid from the heat source to heat the working fluid, an independent auxiliary heat source configured to provide an additional heating fluid in heat exchange relationship with the working fluid, to heat the working fluid. The system is provided with a secondary heater, which is configured to circulate the working fluid in heat exchange relationship with the additional heating fluid from the independent auxiliary heat source and which can be used to replace the heater or in combination with the heater.

摘要： Aircraft power plants including combustion engines, and associated methods for recuperating waste heat from such aircraft power plants are described. A method includes transferring the heat rejected by the internal combustion engine to supercritical CO2 (sCO2) used as a working fluid in a heat engine. The heat engine converts at least some the heat transferred to the sCO2 to mechanical energy to perform useful work onboard the aircraft.

摘要： A steam turbine system (200) includes a steam turbine (60) in which a main flow path (C) through which a main steam flows is formed, and a saturated steam generation portion (210) that is configured to generate a saturated steam. The saturated steam generation portion (210) is configured to feed the saturated steam into a wet region (C1) in which the main steam in the main flow path (C) is in a wet state via a hollow portion formed inside a stator vane (650) of the steam turbine (60). The stator vane (650) has a plurality of supply ports that are formed such that the hollow portion is configured to communicate with the main flow path (C), and a discharge amount of the saturated steam increases from an inner circumferential side toward an outer circumferential side in a blade height direction.

摘要： Various embodiments include a system for transmitting heat from an exhaust gas of an internal combustion engine to a working medium comprising: a first heat exchanger connected to the exhaust gas; a second heat exchanger connected to the working medium and the first heat exchanger; and a heat transmission medium arranged in a predetermined heat exchanger volume and substantially completely in a liquid state with a predetermined volume of heat transmission medium at room temperature and normal pressure. The heat exchangers define the hermetically sealed heat exchanger volume. The heat transmission medium transmits heat from the exhaust gas to the working medium. A ratio between the predetermined volume of the heat transmission medium and the predetermined heat exchanger volume is set such that the heat transmission medium is substantially completely in a gaseous state when a temperature of the exhaust gas exceeds a threshold value.

摘要： The present invention relates to an arrangement comprising a waste heat recovery system (WHR-system) and a method for controlling the arrangement. The arrangement comprises an expansion tank having a constant inner volume, first cooling means configured to cool the working fluid in the condenser and a control unit configured to control the first cooling means such that the working fluid is cooled to a desired condensation temperature in the condenser during operation of the WHR system. The arrangement comprises further a sub-cooler arranged in a position downstream of the condenser and second cooling means configured to cool the working fluid in the sub-cooler, and that the control unit is configured to control the second cooling means such that the working fluid receives a determined subcooling in the sub-cooler during operation of the WHR system.

摘要： An engine cooling system comprises an engine cooling circuit, comprising a first pump structured to circulate engine coolant fluid therethrough. A remote coolant radiator positioned along the engine cooling circuit downstream of the engine and outside of a vehicle cooling package area is structured to transfer heat from the engine coolant fluid to air. A coolant heat exchanger is positioned along the engine cooling circuit in parallel to the remote coolant radiator. A waste heat recovery system comprises a working fluid circuit comprising a second pump. The coolant heat exchanger is positioned along the working fluid circuit and is structured to transfer heat from the engine coolant fluid to the working fluid. An expander is structured to convert energy from the heat transferred to the working fluid from the engine cooling fluid to mechanical energy. A condenser positioned downstream of the expander is structured to cool the working fluid.

Various tubular adapters are adapted to the external dimensions of the heat exchangers and are used to fasten the associated heat exchanger at its connection ends to the exhaust gas carrying housing. Furthermore, a tubular adapter for a corresponding modular system and a vehicle which has a corresponding exhaust heat recovery device are provided.
