Abstract

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.
