A LASER OPTICAL-ACOUSTIC METHOD FOR HYDROCARBONIC FUEL’S QUALITY MONITORING

Interacting electromagnetic radiation with the hydrocarbonic environment is studied with application of two approaches based on classical and quantummechanical theory of molecules structure. Method of laser spectroscopy for the analysis of hydrocarbonic fuel quality is considered. A model of transformation of radiation energy into electric signal and the mechanism of generating of pressure impulse in a cell of the optical-acoustic detector is proposed. The necessity of the optical-acoustic analyzer of quality of hydrocarbonic fuel is shown. A scheme of laser optical-acoustic octane analyzer developed by authors is presented. The technique of measurement octane numbers of analyzed fuel is considered. Mathematical dependences for definition of octane numbers are given.
