Abstract:
1. A two-stroke internal combustion engine with opposed cylinders which utilizes an integrated positive displacement supercharger and regenerator comprising: at least one cylinder housing assembly forming two opposed cylinders sharing a common axis, each cylinder having an outward facing end, an inward facing end facing the other cylinder and, between the ends, a fixed annular partition extending radially inward in the cylinder and having a supercharger side and a regenerator side; two double piston assemblies encircled by the cylinder housing assembly, wherein each double piston assembly includes in each cylinder, a supercharger chamber; in each cylinder, a regenerator chamber separate from the supercharger chamber; an inlet valve assembly at the outward facing end of each cylinder, and a crankpin mounted on the cylinder housing assembly between the opposed cylinders, the crankpin having integrated cam lobes to actuate the at least one exhaust valve and being orientated such that the axis of the crankpin is perpendicular to the common axis of the cylinder housing assembly wherein the fluid flow out of the combustion chamber flows into the regenerator chamber, but fluid does not flow from the regenerator chamber into the combustion chamber.
