Abstract
Combustion engines, and more particularly, integrating a supercritical fluid passageway into a cylinder head and/or cylinder block of an engine, and preferably, a combustion engine. Both a combustion engine system and a method of cooling a cylinder head in an internal combustion engine, utilizing supercritical fluid, are disclosed.
Claims20
A combustion engine system comprising:
- a cylinder head comprising:
- a combustion chamber and an exhaust outlet fluidly coupled to the combustion chamber to output combustion gases;
- and
- a supercritical fluid passageway extending at least partially through the cylinder head to communicate a volume of a supercritical fluid into the cylinder head and draw heat from the combustion gases.
1 more element
A method for cooling a cylinder head in an internal combustion engine comprising:
- providing a cylinder head comprising a combustion chamber and an exhaust outlet fluidly coupled to the combustion chamber to output combustion gases which exhaust outlet outputs exhaust gases in first direction, including a supercritical fluid passageway extending at least partially through the cylinder head to communicate a volume of a supercritical fluid into the cylinder head and draw heat from the combustion gases;
- and
- providing a supercritical fluid and flowing said supercritical fluid in said supercritical passageway in a second direction counter to said first direction.
