Abstract: A cup tappet is disclosed which has a hydraulic play compensation device for a breather valve of an internal-combustion engine. The play compensation device includes a play compensating element which is composed of components of the cup and of the valve shank in order to simplify the cup tappet structurally.

Abstract: A drive mechanism for a fuel injection pump of an internal combustion engine, wherein a drive sprocket and an injection timer unit are arranged in a crankcase of the engine on a drive shaft connected to the camshaft of the fuel injection pump. The drive shaft is formed by a socket sleeve and is floatingly supported on the camshaft.

Abstract: An internal combustion engine arranged in an automotive vehicle with optionally driven units or the like, for example, units driven by way of pulleys. The units extend toward a front if the internal combustion engine is arranged in a front compartment of the automotive vehicle and extend toward the rear beyond the internal combustion engine if the engine is disposed in a rear compartment. The units and optionally their drive elements are fashioned in such a way and/or are mounted to the internal combustion engine in such a manner that, in case of a collision, impact energy is absorbed at the units and/or their fasteners or mounting by the performance of deformation work, by overcoming frictional resistances, and/or by a displacement of viscous substances against a resistance.

Abstract: An arrangement for mounting driven or non-driven assemblies on or to an internal combustion engine mounted in a motor vehicle. The assemblies projecting forward beyond an end of the internal combustion engine when the engine is mounted in a front of the motor vehicle and projecting rearwardly beyond the engine when the engine is mounted in the rear of the motor vehicle. The assemblies are so mounted and/or fastened on or to the internal combustion engine that, in the event of a collision and/or an impact on the assemblies, such assemblies are displaceable in a direction of the internal combustion engine with a zero resistance and without expending any energy absorption.

Abstract: A suction pipe arrangement for reciprocating internal combustion engines with in-line cylinders, in which a common suction pipe with a fastening flange serving for fastening a throttle valve pipe connection is provided for the cylinders, and in which the tuned suction pipes which extend between the cylinder head of the engine and the common suction pipe are subdivided into two groups; the common suction pipe is thereby arranged in the longitudinal direction adjacent the cylinder row approximately at the height of the cylinder head while the first group of tuned suction pipes which branch off from the left portion of the common suction pipe, lead to the right connecting side of the cylinder head and the tuned suction pipes of the second group which branch off from the right portion of the common suction pipe, lead toward the left connecting side of the cylinder head, with each of the tuned suction pipes extending essentially S-shaped.
