Abstract
An internal combustion engine has a chamber that has a longitudinal centerline, inlet valving operable to admit constituents of a combustible mixture into the chamber for combustion in the chamber to provide a pressure increase in the chamber and outlet valving operable to release an outflow of liquid from the chamber under an influence of the pressure increase. An annular flow passage is defined in the chamber to conduct liquid towards the outlet valving and cause spiraling of the liquid in the flow passage by which a rotatable part exposed to the spiraling flow is caused to rotate. An electrical generator disposed externally of the chamber is driven by rotation of the rotatable part.
Claims39
An internal combustion engine comprising:
- a chamber having a longitudinal centerline;
- inlet valving operable to admit constituents of a combustible mixture into said chamber for combustion in said chamber to provide a pressure increase in said chamber;
- outlet valving operable to release an outflow of liquid from said chamber that is driven towards said outer valving under an influence of said pressure increase as an energy output of said chamber;
- an annular flow passage defined in said chamber, said annular flow passage configured to conduct said liquid towards said outlet valving and cause a spiraling flow of said liquid in said flow passage by which a part exposed to said spiraling flow is caused to rotate;
- and
- an electrical generator to be driven by rotation of said part.
An internal combustion engine comprising:
- a chamber having a longitudinal axis;
- inlet valving operable to admit constituents of a combustible mixture into said chamber for combustion therein to provide a pressure increase in said chamber;
- outlet valving operable to release an outflow of liquid from said chamber that is driven towards said outlet valving under an influence of said pressure increase as an energy output of said chamber;
- and
- a spiraling wall in said chamber that at least in part defines a spiraling flow passage along which said liquid flows towards said outlet valving.
A power generation method in an internal combustion engine comprising:
- providing a combustible mixture in a chamber;
- providing a liquid in said chamber;
- closing said chamber and combusting said combustible mixture in said closed chamber to provide a pressure increase that acts on said liquid in said chamber to cause said liquid to flow towards an outlet of said chamber along a spiraling flow passage that is at least in part defined by a spiraling wall disposed in said chamber;
- and
- opening said outlet to release at least a portion of said liquid from said chamber as an energy output of said internal combustion engine.
