Abstract
An improved configuration for an opposing piston-opposing cylinder ('OPOC') internal combustion engine with a single camshaft to reduce friction between the pistons and the cylinder walls during the combustion phase of the engine cycle. The improvements are presented in two embodiments that provide offsets between the bore axes of the cylinders and the crankshaft axis of rotation to cause the connecting rods to achieve an orientation substantially parallel to the cylinder bore at TDC and shortly thereafter.
