Abstract:
This paper presents a method to determine the octane number of gasoline products using a piezoelectric lateral electric field resonator. The dependence of permittivity of the gasoline on its octane number was measured. It has been shown that, for Russian gasoline grades, there is an unique dependence of aforementioned parameters. It has been found theoretically and experimentally that the frequency of the parallel resonance insignificantly changes with the change of the permittivity of gasoline contacting with free surface of the resonator. Our analysis shows that the value of the real part of the electrical impedance on the resonant frequency is unambiguously determined by the octane number of the gasoline. We provide an example of the determination of the octane number of an arbitrary mixture of different gasoline grades. We also consider the temperature of the gasoline sample under study.
