Title: Combustion engine

Abstract: A combustion engine that has at least a plurality of power strokes during a complete cycle of engine operation that is of compact packaging and Brayton cycle operable. In a preferred embodiment, a piston-cylinder arrangement used to compress air and deliver it to a combustion chamber where it is combusted along with fuel. The combustion gases are returned back to the piston-cylinder arrangement where they act on the piston to output power in a power stroke. A second power stroke can be implemented where additional combustion gases are available to extract additional power from. In a preferred embodiment, the same piston-cylinder arrangement receives the additional combustion gases from the combustion chamber in the second power stroke.
