Abstract (en)

[origin: EP1887218A2] Laser ignition device for an internal combustion engine comprises a laser light-generating device (3) for introducing laser light at a maximum intensity of 0.15 mJ/mm 2>or a minimum intensity of 3 mJ/mm 2>into a combustion chamber. The intensity is attained on a side of a clean combustion chamber window (7~) facing the combustion chamber. An independent claim is also included for an internal combustion engine comprising the above laser ignition device. Preferred Features: The laser light-generating device introduces pulsed laser light (5) with a pulse duration of 0.1-20, preferably 0.5-10 ns into the combustion chamber. The intensity is an average intensity determined over the time of the pulse duration.
