Two stroke apposed pistons parallel cylinders internal combustion engine

As is known, the present mechanical engineering for internal combustion engines provides substantially for two types of engines, namely four-stroke engines, and two-stroke engines, utilizing either the Otto or the Diesel cycle. This invention concerns a rocker arms two-stroke opposed-piston internal combustion piston engines. The first opposed-piston engine was invented by Hugo Junkers around the end of the nineteenth century. Junkers’ basic configuration uses two pistons disposed of crown-to-crown in a common cylinder having inlet and exhaust ports near bottom-dead-Centre of each piston, with the pistons serving as the valves for the ports. Bridges Support transit of the piston rings past ports. This engine has two crankshafts, one disposed at each end of the cylinder. The crankshafts, which rotate in the same direction, are linked by rods to respective pistons. Wrist pins link the rods to the pistons.
