Conjoined piston engine with Free valve system.

My Conjoined piston engine. A new type of internal combustion engine, composed partly of two crankshafts spinning opposite directions. They are kept in sync with a simple gear system. This is simply a different way of building the short block of an many as reduced less moving parts, higher revs, more power, and perfect primary and secondary balance.. Here are the technical specs....... There would be one or two ring gears (with teeth numbering 2x) attached to or part of the pistons surrounding the crankshafts with their diameter equal to the throw of both crankshafts combined or (2y). One or two gears (with teeth numbering x and diameter equal to y) attached to the primary crankshaft affixed to the rod journal so that they ride inside of the ring gear(s). The main crankshaft and secondary (or eccentric lobe) will have the same offset, therefor if each crankshaft has a throw of two inches the pistons would then travel a total of four inches. The engin
