摘要： The invention relates to a laser ignition plug (100), comprising an antechamber (110), wherein the laser ignition plug (100) is designed to radiate, in particular to focus, laser radiation (24) guided and/or generated in the laser ignition plug (100) onto at least two ignition points (ZP1, ZP2) located in the antechamber (110), which are different from one another. According to the invention, the laser ignition plug (100) is designed to radiate the laser radiation (24) into the antechamber (110) such that a distance (d12) between at least one first ignition point (ZP1) and a second ignition point (ZP2) adjacent thereto is greater than a minimum distance (d2min) of the first and/or second ignition points (ZP1, ZP2) to an inside surface (110a) of the antechamber (110).

摘要： Disclosed is a laser spark plug for an internal combustion engine (10), comprising at least one means (26) for guiding, forming, and/or generating laser radiation (24), further comprising a combustion chamber window (58) and a housing (38). Said laser spark plug is characterized in that the housing (38) includes a diaphragm (74) to allow the laser radiation (24) guided, formed, and/or generated by the means (26) to penetrate into a precombustion chamber (110) located at the combustion chamber end (381) of the housing (38), said diaphragm (74) being located on the side of the combustion chamber window (58) that lies opposite the means (26). At least one overflow duct (120) provides a fluid connection between an interior (111) of the precombustion chamber (110) and a combustion chamber surrounding the precombustion chamber (110). Said at least one overflow duct (120) is disposed and designed such that a fluid flow (F) is generated which enters the interior of the diaphragm (74) at a minimum angle ε of 45°, in particular measured in relation to the longitudinal axis of the laser spark plug, when a fluid flows into the interior (111) of the precombustion chamber (110) via the overflow duct (120).
