Method of determination of diesel oil aging level and its application to diesel oil quality estimation
- Summary:
Invention describes method of determination of diesel oil aging, as well as its application for estimation of diesel oil quality during storage. Measurements are performed by using electrochemical impedance spectroscopy, which allows recording of impedance spectra in the form of Nyquist plot, i.e. plot of imaginary component of impedance, Zim, as a function of real component of impedance, Zre. Analysis of this plot allows for calculation of parameters characteristic for state of the studied oils and allowing for determination of their aging level from early stages of the process.
