Abstract (en)

[origin: WO2011041807A2] The invention relates to a laser spark plug, comprising a laser light-producing device (2) and a spark plug housing (1) at the end of which facing the combustion chamber an injection lens (10) for injecting laser light into the combustion chamber (30) of an internal combustion engine is arranged, the spark plug housing (1) comprising a fastening zone (7) for fastening the laser spark plug in a cylinder head (17) of the internal combustion engine. A projection (31) on the end of the spark plug housing (1) facing the combustion chamber houses the injection lens (10), the outer diameter (D1) of the projection (31) being smaller in the area of the injection lens (10) than the outer diameter (D2) of the spark plug housing (1) in the fastening zone (7).
