This patent describes a lever type internal combustion engine. It comprises power cylinders arranged in side-by-side opposed pairs and disposed in a first horizontal plane, each provided with a piston and a piston rod pivotally connected at an inner end with the piston, a crankshaft supported for rotation about an axis lying in a second horizontal plane disposed in spaced parallel relationship with and below the first horizontal plane, and a lever system whereby the power cylinder pistons drive the crankshaft, the lever system, one for each pair of opposed power cylinders, comprising an elongate level arm pivotally interconnected at a first end with the outer ends of the piston rods, means including guide members disposed below the crankshaft for constraining a second end of the lever arm for up and down movement in a direction perpendicular to the first and second horizontal planes, and means for operatively connecting the lever arm at a point intermediate its first and second ends to the crankshaft, whereby the lever arm functions as a lever of the second class between the piston rods and the crankshaft the constrained second end thereof functioning as the fulcrum therefor.
