Patent ID: 8701613

Claim:
A laser ignition plug, comprising: an antechamber into which the laser ignition plug is configured to irradiate laser radiation, wherein the antechamber defines at least two overflow ducts, which form a fluid connection between the antechamber and a chamber region surrounding the antechamber, wherein 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 the combustion chamber, of the antechamber, and (iii) the alignment and/or geometry thereof, are arranged and/or configured asymmetrically with respect to the longitudinal axis of the antechamber, and wherein a second cross-sectional area of at least one second overflow duct is determined according to: a first cross-sectional area of a first overflow duct, a second path length starting from the antechamber along a longitudinal axis of the second overflow duct as far as a second wall portion of a combustion chamber wall, which is opposite the second overflow duct in the installed position of the laser ignition plug in an internal combustion engine, and a first path length starting from the antechamber along a longitudinal axis of the first overflow duct as far as a first wall portion of the combustion chamber wall, which is opposite the first overflow duct in the installed position of the laser ignition plug in the internal combustion engine.
