Scope

Scope: This document specifies the test method for analyzing the content of polycyclic aromatic hydrocarbons, freezing point, cold filter plugging point, cetane number, and cetane index in automotive diesel using near-infrared spectroscopy. This document is applicable to the rapid analysis of quality indicators of automotive diesel. Main technical content: By using the overtone or combination of the stretching vibration of hydrogen groups in chemical bonds, the absorption spectra in the near-infrared region are obtained by transmission or reflection. Modern chemometric methods such as principal component regression and partial least squares are used to establish a linear or non-linear relationship (correction model) between the near-infrared spectra of automotive diesel products and their quality indicators, thereby enabling the rapid analysis of the content of polycyclic aromatic hydrocarbons, freezing point, cold filter plugging point, cetane number, and cetane index in the samples to be tested using spectral information.
