Control octane number of gasolines with differential backscattering method

Applicability of differential backscattering method to the control octane numbers of gasolines is investigated. The introduced method allows to register octane number to within 0,3 octane units, that is comparable to accuracy methods of adsorptive and infrared spectroscopy. Advantage of introduced method is the opportunity of work in a mode of real time and absence of basic restrictions on thickness and movement speed of researched gasolines mixes.
