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.
Claims14
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, and
- 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.
An internal combustion engine, comprising:
- at least one laser ignition plug having 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 overflow ducts in the antechamber, with regard to one or more of the radial spacing thereof from a longitudinal axis of the antechamber, 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 in such a way that ignition torches of ignited fuel exiting from the overflow ducts reach wall portions of a combustion chamber at the same time, said wall portions being arranged in a primary direction of propagation of the ignition torches.
