Disclosed is a simple, easy-to-produce, and reliable connection between a shaft of a gas exchange valve and an actuator. This connection is detachable and, as a result, can be connected and disconnected multiple times. It is also possible to dispose the coupling piece on the shaft of the gas exchange valve and provide circumferential grooves on the control element of the actuator.

Detachable connection for coupling a gas exchange valve of an internal combustion engine to an actuator

A connection between a shaft end of a gas exchange valve of an internal combustion engine and a final control element of a valve actuator, with at least two shell-shaped wedge-shaped pieces, surrounding the shaft end and braced on the final control element, whose radially outer circumferential surface extends conically and which are surrounded by at least one conical clamping sleeve whose radially inner circumferential surface extends complimentary to the cone angle of the wedge-shaped pieces, wherein on the radially inner circumferential surface of the wedge-shaped pieces and on the radially outer circumferential surface of the shaft end of the gas exchange valve, protrusions and recesses that mesh with one another are provided. To enable rotary motions of the shaft end relative to the wedge-shaped pieces, the latter adjoin one another without gaps in the circumferential direction, forming an encompassing wedge-shaped sleeve, whose inside diameter is slightly larger than the outside diameter of the shaft end of the gas exchange valve, and that the protrusions and recesses mesh with one another with slight play.

Connection between a shaft end of a gas exchange valve of an internal combustion engine and a final control element of a valve actuator

An internal combustion engine, especially for a motor vehicle, is described which is provided with a control apparatus. A number of functions can be executed at time intervals and/or in dependence upon the rpm of the engine. Furthermore, a quantity (RA), which defines the utilization of the control apparatus, and a quantity (N), which defines the rpm of the engine, can be determined. The number of executed functions can be reduced by the control apparatus when the quantity (RA), which defines the utilization, is greater than a utilization threshold value (ASW ).

Method for operating an internal combustion engine, especially of an automobile

In the process for controlling industrial operations and processes, a complex control program is processed by a microprocessor of a controller (,) under real-time conditions. The complex control program is divided into tasks. Each task is assigned a priority and an activation event. The activated task with the highest priority for processing is selected. Processing of a task can be interrupted on the basis of a subsequent request for processing a higher-priority task Processing of the lower-priority task is continued at the point of the interruption, after the processing of the higher-priority task is concluded. This process is characterized in that tasks can be divided into a number of subtasks to be processed sequentially, and within configurable, coherent and non-overlapping priority ranges, tasks can interrupt other lower-priority tasks only between two successive subtasks or at interruption points explicitly inserted by the user. Processing of the higher-priority task requested later is not begun until processing of the subtask during which the request for processing the higher-priority task was issued has been completed.
