Abstract (en)
[origin: WO0140753A1] The invention relates to a device for monitoring the combustion processes occurring in the combustion chamber of an internal combustion engine, which comprises a housing (1), which may be built into the wall of the combustion chamber, with a measuring section which extends to the combustion chamber and with a number of drillings (3), which extend along the longitudinal axis of the housing, in each of which an optical guide (2) is arranged. A first end of an optical guide, lying at the first end of the drilling, receives light from inside the combustion chamber and a second end of said optical guide is linked to an opto-electronic analyser. The drillings have an end section (3A), adjacent to the combustion chamber, which extend out of the housing, through an outer surface of the measuring section, at an angle ( alpha ) to the longitudinal axis of the housing. The first end of the optical guide comprises a light-admitting opening directed at the inner end of the end section and a mirrored surface, lying opposite said opening, which reflects light in the direction of the longitudinal axis of the optical guide.
