Abstract:
1. A heat engine using a working fluid comprising: a center assembly having a first compression chamber and second compression chamber internally, said center assembly having a main wall, a first end wall, and a second end wall sealing said center assembly; a first piston assembly seal-ably attached to said first end wall of said center assembly, a second piston assembly seal-ably attached to said second end wall of said center assembly, said first and second piston assemblies each including a burner, piston cavity, piston with piston head and piston shaft, said piston shaft of said first piston assembly interconnected to said piston shaft of said second piston assembly, said burners in contact with said respective piston cavities to provide heat to the working fluid in said respective piston cavities; a heat exchanger connected to said center assembly by a passage to direct the working fluid via said passage to said center assembly, said heat exchanger connected to said first piston assembly and said second piston assembly to receive the working fluid from said first piston assembly and said second piston assembly, said heat exchanger connected to said burner to direct heated gas to said respective burners for combustion of said heated gas; wherein said first piston assembly includes an inlet port connected to an outlet port of said first compression chamber; wherein said second piston assembly includes an inlet port connected to an outlet port of said second compression chamber; wherein said first piston assembly includes at least one outlet port connected to a first inlet of said heat exchanger; wherein said second piston assembly includes at least one outlet port connected to a second inlet of said heat exchanger; wherein said heat exchanger includes a first outlet connected to said center assembly and a second outlet connected to said center assembly; wherein said center assembly includes at least one outlet port on each of said first end wall and said second end wall which lead from inside of said center assembly to said respective piston cavities of said first piston assembly and said second piston assembly to allow working fluid to flow from said center assembly to said first piston assembly and said second piston assembly; and wherein said center assembly includes two inlet ports on each of said first end wall and said second end wall, said two inlet ports connected to said first and second compression chambers to allow working fluid to flow from said respective piston cavities of said first piston assembly and said second piston assembly to said first and second compression chambers.
