摘要： A laser spark plug, in particular for an internal combustion engine, having a combustion chamber window through which laser radiation may be emitted from an interior of the laser spark plug toward an exterior, the laser spark plug having a component which surrounds at least part of the beam path of the laser radiation in the area of the exterior. In particular, the laser spark plug, in the area of the component, has at least one channel which has at least two orifice sections and which allows fluid communication between the orifice sections, a first orifice section being situated in the area of an outer surface of the combustion chamber window, and a second orifice section being situated in a radially outer area of the laser spark plug, in particular of the component.

摘要： A laser spark plug, e.g., for an engine, includes a prechamber that accommodates an ignitable medium, an arrangement for radiating laser radiation onto an ignition point in the prechamber, at least one crossflow channel that enables a fluid connection between an internal space of the prechamber and an external space, and a screen arranged between the radiating arrangement and the prechamber with an outlet opening for entry of the laser radiation into the prechamber. The at least one crossflow channel is arranged to provide a fluid flow therethrough and into the prechamber, such that the direction of flow forms an angle of a maximum of approximately 30° with a longitudinal axis of the prechamber, and the flow is directed into a spatial region of the prechamber that is situated essentially predominantly, preferably completely, outside a central region of the outlet opening of the screen.
