The present invention concerns an engine comprising at least a cylinder (1) that forms a combustion chamber (50). In accordance with the invention, at least a photovoltaic surface (60) is foreseen, arranged in such a way as to result hit by the light produced as a consequence of a combustion that takes place in the combustion chamber (50). In particular, at least an optical fiber (10) is foreseen, passing through said combustion chamber (50) in such a way as to be irradiated, in use, by the light emitted as a consequence of said combustion that takes place inside said chamber (50). In accordance with this solution, the photovoltaic panel (60) is arranged externally to the combustion chamber in such a way as to be irradiated by the light transported by said optical fiber (10) in exit from the cylinder.

A Rankine cycle includes an waste-heat recovery device that is configured to exchange heat between cooling water coming out from an engine and exhaust gas exhausted from the engine, a heat exchanger including an evaporator through which the cooling water coming out from the engine flows to recover waste-heat of the engine to refrigerant, and a superheater through which the cooling water coming out from the waste-heat recovery device flows to recover the waste-heat of the engine to the refrigerant, an expander that is configured to generate power using the refrigerant coming out from the heat exchanger, a condenser that is configured to condense the refrigerant coming out from the expander, and a refrigerant pump that is configured to supply the refrigerant coming out from the condenser to the heat exchanger by being driven by the expander. The cooling water coming out from the superheater is returned to the engine after being joined with the cooling water coming out from the evaporator.
摘要:
Aspects of the invention disclosed herein generally provide heat engine systems and methods for recovering energy, such as by generating electricity from thermal energy. Generally, the heat engine system has a working fluid circuit containing a working fluid (e.g., sc-CO 2 ) for absorbing thermal energy from the heat source stream via a heat exchanger. In one aspect, the method includes controlling a power turbine by modulating a turbo pump throttle valve and a power turbine bypass valve to adjust the flowrate of the working fluid entering the power turbine while monitoring and controlling process operation parameters of the heat engine system to synchronize the frequency of the power generator to the frequency of the electrical grid during a synchronization process.
