In a reciprocating piston internal combustion engine with a piston which is displacably arranged in a cylinder and is coupled in to a connecting rod whose movement can be transmitted to a crankshaft via a crank, a transmission element is provided between the connecting rod and the crank of the crankshaft and the movement of the transmission element can be manipulated by means of a control arm for an adjustment of the compression ratio of the engine. The transmission element is coupled to the crank via a joint disposed in the intermediate region between a bearing connection of the transverse lever structure with the control arm and a bearing connection of the transverse lever with the connecting rod, the bearing connection of the transverse lever with the connecting rod, the crank and the control arm being arranged in a predetermined relationship.

Reciprocating piston internal combustion engine

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.

In an internal combustion engine comprising an engine block consisting of a crankcase, at least one cylinder sleeve extending from the crankcase and a coolant jacket disposed around the cylinder sleeve or sleeves and a cylinder head mounted on the engine block, the coolant jacket is a separate component consisting of a material lighter than the normally used cast iron jacket and is firmly engaged between the crankcase and the cylinder head which is mounted onto the cylinder sleeve or sleeves.
