ABSTRACT:
A peristrophic internal combustion engine with increased power output has greater torque and reduced friction. The distance of rotation between the inertia weights and the crankpins is increased to increase torque. These transposed inertia weights are embodied in top and bottom journals of the connecting rods and in the pistons assemblies. Each piston assembly includes a top piston-ring-holder piston and a lower, bearing piston joined to reciprocate in the cylinder. The lower bearing piston may have a circumferential ring, cylindrical barrel rollers, or spherical ball bearing arrangement contacting the cylinder wall while the upper piston carries the piston rings. The spherical ball bearing arrangement allows lower piston rotation about the piston axis. Inner and outer cylinder liners increase the cylinder operating life and reduce combustion heat loss through the cylinder wall.
