Abstract: A method for removal of a workpiece part from a residual workpiece of a sheet-like workpiece includes detecting an interlocking of the workpiece part with the residual workpiece. The workpiece is fixed for machining by a holding device and movable in an X-Y plane of the workpiece. The workpiece part is formed by cutting machining on the workpiece resting on a workpiece support. Before or after the cutting, a gripper device is positioned in a removal position relative to the workpiece part, and the gripper device is activated and the workpiece part is gripped in its position resting on the workpiece support. The method includes initiating at least one release strategy for automatic workpiece removal. At least one travelling movement with at least one travel path of at least one of the holding device and the gripper device is activated with at least one movement component in the X-Y plane.

Abstract: A method for machining a plate-like workpiece with a processing machine includes forming a receptacle in the plate-like workpiece for an insert part and machining the receptacle based on one or both of an orientation at which the insert part is to be inserted into the receptacle and a side of the plate-like workpiece from which the insert part is to be inserted into the receptacle. The method further includes running a machining program to carry out the forming and the machining of the receptacle. A computer program product is provided to configure a programming system by which the machining program is generated.

Abstract: An internal combustion engine for a motor vehicle, having at least one adjusting device by means of which at least one compression ratio of the internal combustion engine is variably settable. At least one detection device is provided by means of which at least one signal (20, 22) which characterizes an actuation effort for setting the compression ratio is detectable. The invention further relates to a method for checking an adjusting device of such an internal combustion engine.

Abstract: The invention relates to a gasoline engine having a catalyst for reducing the emission pollutants, with an oxygen absorption device located in the exhaust line upstream of the catalyst. According to the invention, the gasoline engine is operated in a first operating range with a lean air/fuel ratio (.lambda.), and oxygen is removed from the exhaust by the absorption device. In a second operating range, the gasoline engine is operated at .lambda.=1, and the absorption device is bypassed or deactivated. In the case of a gasoline engine with a Denox catalyst the gasoline engine is operated constantly with a lean air/fuel ratio, with the active surface of the Denox catalyst being "depoisoned" temporarily by activating the oxygen absorption device.

Abstract: A reciprocating piston is disclosed with variable compression height for internal combustion engines in particular. For structural simplification of the temperature-dependent change in the compression height of the reciprocating piston, a spring is provided which consists of a shape memory alloy and interacts with the pressure limiting valve. This permits temperature-dependent change in the compression height of the reciprocating piston exclusively by the pressure limiting valve so that structural simplification is achieved.
