Abstract

In a reciprocating internal combustion engine having first and second cylinder banks arranged adjacent each other so that the axes of their cylinders extend essential parallel, a crankshaft is rotatably supported at an end of the cylinder banks between the longitudinal axes of the cylinders of the first and second cylinder banks and includes crank pins, on which cross-levers are rotatably supported and piston rods connected with an end to the pistons are rotatably supported with their other ends on the cross levers which have sidewardly extending portions controllably supported by control arms for adjusting the compression ratio in the cylinders of the engine.
