    Abstract: The invention relates to a mechanical valve play compensation element for a valve drive on a piston combustion engine, comprising a first pressure part (1) which is axially displaceable in relation to a second pressure part (2) and which is fixed in such a way that it can turn about the axis of displacement; a torsion spring element (10) which acts between the first pressure part (1) and the second pressure part (2) and is axially flexible at least to a certain extent; and at least one helical surface (9.1) on the first pressure part (1), to which a corresponding helical surface (9.2) on the second pressure part (2) is allocated, these forming a pair of helical surfaces (9). The surfaces of the helical surface pair (9) are configured as a rough surface and are pressed against each other by the torsion spring element (10).

    Abstract: The present invention relates to a piston-type internal combustion engine comprising gas-exchange valves which can be driven in a completely variable manner by a motor control (2) and which communicate with an air supply channel (4) provided with a device (6) for generating a negative pressure using the energy components of the air flowing through said air supply channel (4). This device is provided with means that can be driven for adaptation to the modifications in the flow energy which are inherent to the operation, and communicates with at least one negative-pressure user (8, 9, 10) through at least one negative-pressure duct (7).

    Abstract: A method for operating a piston-type internal-combustion engine having electromagnetic valve trains for actuating the cylinder valves, which respectively have an armature that can move back and forth between two electromagnets, counter to the force of restoring springs, with the valves being completely variably actuated by an electronic engine timing control unit. The functioning of the electromagnetic valve trains of each cylinder is detected in the engine timing control unit during operation, and when a functional failure of an electromagnetic valve train is detected at a cylinder, the electromagnet of the failed electromagnetic valve train is acted upon with a capturing current, which brings the armature into an end position at an electromagnet, and from this end position, the electromagnetic valve train is actuated for the ongoing work cycle of the cylinder.
