Abstract
An internal combustion engine having a cylindrical outer case(s) defining a base compression cylinder(s) with an inner cylindrical cylinder(s) defining power cylinder(s) circumferentially spaced in the engine and each housing opposing intake and exhaust pistons. Inlet ports for supplying pressurized air to the pistons included a small percentage of base compression air stored in an accumulator at a pressure that is the highest pressure in the engine. Flex tubes judiciously mounted in the piston and attached at either end to the piston and piston ring for supplying air from the accumulator to a plurality of pockets formed in the piston ring to hydrostatically support the pistons and piston rings. The pistons power a rotary cam mounted on opposing ends of the engine and a cam follower system positions the pistons for the 2-cycle operation. A four bar linkage system operatively connected to the piston rod to minimize piston side loads. The passage between the power cylinder and base compression cylinder serves to admit heated air, indirectly heated during the combustion cycle, charges the power cylinder for improved efficiency. The absence of the block and the material used for the hot section of the engine are made from relatively light weight materials providing a significantly improved power to weight ratio.
