摘要： A laser spark plug for an internal combustion engine includes at least one element for guiding, shaping and/or generating laser radiation, a combustion chamber window and a housing. The housing has, on the opposite side of the combustion chamber window from the element, an aperture for the passage of the laser radiation guided, shaped and/or generated by the element into a prechamber disposed at the end of the housing on the combustion chamber side. At least one overflow channel is provided for a fluid connection between an internal space of the prechamber and a combustion chamber surrounding the prechamber. When a fluid flows into the internal space of the prechamber through the overflow channel, a fluid flow is obtained that enters the interior of the aperture at a minimum angle ε, in particular measured with respect to the longitudinal axis of the laser spark plug, of 45°.

摘要： A laser spark plug device for an internal combustion engine includes a prechamber for receiving an ignitable medium and at least one overflow channel providing a fluid connection between an internal space of the prechamber and an external space surrounding the prechamber. The at least one overflow channel is configured such that when a fluid flows through the overflow channel into the internal space of the prechamber, the result is a fluid flow having at least one eddy which rotates on an eddy axis forming an angle of more than approximately 45° with a longitudinal axis of the laser spark plug device.

摘要： A laser ignition plug includes an antechamber into which the laser ignition plug is configured to irradiate laser radiation. The antechamber defines at least two overflow ducts that realize a fluid connection between the antechamber and a spatial region surrounding the antechamber. The at least two overflow ducts, with regard to one or more of (i) the radial spacing thereof from a longitudinal axis of the antechamber, (ii) the axial spacing thereof from an end region, which faces toward the combustion chamber, of the antechamber, and (iii) the alignment and/or geometry thereof, are arranged asymmetrically with respect to the longitudinal axis of the antechamber.
