Abstract
A split-cycle engine includes: a first cylinder housing a first piston, wherein the first piston performs an intake stroke and a compression stroke, but does not perform an exhaust stroke; a second cylinder housing a second piston, wherein the second piston performs an expansion stroke and an exhaust stroke, but does not perform an intake stroke; and a valve chamber housing a valve, the valve comprising an internal chamber that selectively fluidly couples to the first and second cylinders, wherein the valve and internal chamber move within the valve chamber and relative to the first and second cylinders.
Claims22
A split-cycle engine comprising:
- a first housing comprising a first piston, wherein the first piston performs an intake stroke and a compression stroke, but does not perform an exhaust stroke;
- a second housing comprising a second piston, wherein the second piston performs an expansion stroke and an exhaust stroke, but does not perform an intake stroke;
- and
- a valve housing comprising a valve chamber, wherein the valve chamber moves within the valve housing to selectively fluidly couple the valve chamber to the first and second housings.
A method of operating a combustion engine comprising:
- compressing a working fluid in a first housing, the first housing comprising a first piston that performs an intake stroke and a compression stroke, but does not perform an exhaust stroke;
- transferring the working fluid from the first housing to a valve chamber, wherein the valve chamber moves within a valve housing;
- and
- transferring the working fluid from the valve chamber to a second housing, the second housing comprising a second piston that performs an expansion stroke and an exhaust stroke, but does not perform an intake stroke.
