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.

A split-cycle engine comprising:
- 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 cylinder 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 linearly and reciprocally within the valve cylinder and relative to the first and second cylinders, and wherein the valve has a port that fluidly couples the internal chamber to the first and second cylinder simultaneously.
A method of operating a combustion engine comprising
- compressing a working fluid in 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;
- transferring the working fluid from the first cylinder to an internal chamber of a valve, wherein the valve is housed in a valve cylinder of the engine;
- and
- transferring the working fluid from the internal chamber to 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, wherein
- the internal chamber selectively fluidly couples to the first and second cylinders, wherein the valve and internal chamber move linearly and reciprocally within the valve cylinder and relative to the first and second cylinders, and wherein the valve has a port that fluidly couples the internal chamber to the first and second cylinder simultaneously.
