Abstract
An apparatus, comprising an engine, and an energy-management system configured to recirculate, at least in part, carbon dioxide relative to the engine in such a way that the carbon dioxide exchanges, at least in part, energy relative to the engine once the carbon dioxide is made to recirculate, at least in part, along the energy-management system.
Claims28
A energy management apparatus for a combustion chamber of an internal combustion engine, comprising:
- a heat exchange structure at least partially surrounding the combustion chamber;
- and
- a cooling system including a pressurized carbon dioxide cooling medium,
- at least one pressure-reducing device,
- at least one intake assembly connected between the pressure reducing device and the heat-exchange structure,
- a spray-generating device within each intake assembly, the spray-generating device introducing droplets of the cooling medium into the heat-exchange structure,
- at least one outlet assembly extending from the heat exchange structure being spaced apart from the intake assembly,
- a control system for controlling the temperature of the engine and the temperature and pressure of the cooling medium,
- a closed-loop circulation circuit conveying the carbon dioxide cooling medium from the at least one outlet assembly to the at least one pressure reducing device,
- wherein the mass flow of the cooling medium through the closed-loop circulation circuit is controlled by the at least one spray-generating device and the at least one pressure-reducing device under operational control of the control system.
7 more elements
A method of cooling a combustion chamber of an internal combustion engine with a heat-exchange structure at least partially surrounding the combustion chamber, the method consisting of:
- circulating a cooling medium containing carbon dioxide in a closed-loop circuit of a cooling system,
- dropping the pressure of the carbon dioxide cooling medium with a pressure-reducing device, and thereafter directing the carbon dioxide cooling medium into the heat-exchange structure partially surrounding the combustion chamber to draw the heat away from the combustion chamber.
