Abstract
A process and device for determining the composition of an alcohol-petrol mixture supplying a combustion engine. According to this process a light beam is emitted through the mixture supplying the engine, the degree to which this beam is absorbed by the mixture is determined in a wave length chosen in the wave length range corresponding to the near infra-red and adjustment of the operating parameters of the engine is controlled as a function of the degree of absorption thus measured.
