摘要:
An ignition system is described, in particular for an internal combustion engine of a motor vehicle, having a laser spark plug, a pump module for supplying the laser spark plug with pump radiation, and an optical fiber device for transmitting the pump radiation from the pump module to the laser spark plug. At least two separate signal transmission devices which each extend at least partially along the optical fiber device, and an evaluation unit, which is designed to act on each of the signal transmission devices with a test signal, to evaluate a response signal of the signal transmission devices which results from the particular test signal, and from the response signal to deduce an operating state of the corresponding signal transmission device, are provided.

A shaft comprising functional elements, such as an assembled camshaft for an internal combustion engine, a method for producing such shafts, and internal combustion engines equipped with such shafts. The functional elements each have a bore and are produced separately from the shaft main body, and the bore is subsequently press fit onto the shaft body to attach the functional element in an axially and rotationally fixed manner. The shaft is also provided with at least one roller bearing that includes at least one undivided roller bearing element which is mounted on the shaft body between two functional elements, for example, by press fitting.

A nut assembly comprised of a nut body (1a) and a pressure disk (2a) and a method for producing the same. The nut body has a drive portion, such as a polygonal portion, for engaging with a tool and an abutment region that can be brought into contact with the supporting surface of the pressure disk arranged on the nut body in a non-releasable manner. The pressure disk has a central opening into which a neck formed on the nut extends axially at least in part, and the neck has a projection which radially overlaps or engages the thrust ring in order to form the non-releaseable connection.

The invention relates to both nut assemblies and methods for producing the same. Said nut assemblies consist of a nut body (1a) and a pressure disk (2a). The nut body has a drive portion, such as a polygonal portion, for engaging with a tool and an abutment region that can be brought into contact with the supporting surface of the pressure disk arranged on the nut body in a captive manner. The pressure disk has a central opening into which a neck formed on the nut extends axially at least in part. The neck has a projection for forming a captive connection. This projection radially overlaps or engages the thrust ring.

An ignition device for an internal combustion engine, in particular of a motor vehicle, includes at least one pump light source, which provides a pump light. Furthermore, a laser device is provided, which is able to generate a laser light for beaming into a combustion chamber. A waveguide device transmits the pump light from the pump light source to the laser device. The laser device includes at least one refraction device, for example, a lens, which refracts the pump light and is in one piece therewith.
