ABSTRACT:
A gas or diesel internal combustion engine of either a two or four stroke design uses both ends of each piston to create a combustion chamber. The piston rod rides linearly through a lower cylinder head. The lower cylinder head forms a lower combustion chamber with its own set of valves and fuel/air inlet. A second set of lower cams and camshaft operate the lower set of valves. Crankcase oil is pumped up the middle of the piston rod to an outlet in the center of the piston.
