ABSTRACT:
An arrangement for determining the parameters of an internal combustion engine, in particular an Otto engine operating with gaseous fuels, has at least one optical sensor for observing the emission of light caused by the combustion in a combustion chamber of the internal combustion engine and at least one photodetector for converting the light emitted into electric signals which are processed in an evaluation unit. In order to achieve a rapid and accurate regulation, the evaluation unit has an arrangement for determining the maximum or mean intensity of the light emitted during each combustion cycle on the basis of the corresponding electric signal. The evaluation unit further has a regulating unit which regulates at least one engine parameter depending on the intensity maxima.
