ABSTRACT:
The engines may be of either the swing beam or the rocker beam type and each has its crankshaft in a central, transverse plane of the block. Each engine has at least one pair of cylinders with each having a piston and a head. A link pivotally connected to each piston is connected to the appropriate one of a pair of beams, one on each side of the central plane and each pivotally connected to the block. Each beam is pivotally connected to the appropriate one of the crankshaft connecting rods. The moving paired parts, i.e. the pistons, links, beams and connecting rods, are so formed and positioned with reference to the central transverse plane that a plane inclusive of any feature of the moving parts and the crankshaft axis defines an angle with respect to a plane inclusive of the corresponding feature on the opposite side of the central plane and the crankshaft axis that does not exceed .+-. 4.degree. and the perpendicular radial distance between corresponding features of the moving parts and the crankshaft axis differ by no more than .+-. 8%. The working surfaces of the block constraining the motion of the moving parts are subject to the same limitations. The moving parts on each side of the central plane may be axially aligned or axially offset. In all embodiments of the invention, the crankshaft axis is an axis of symmetry and the engine possesses effective dynamic balancing properties.
