    (Видавництво Львівської політехніки, 2023-02-28) Shpak, Oksana; Velykiy, Nazariy; Lviv Polytechnic National University; Lviv State University of Life Safety
    The principle of device operation for determining the quality control of diesel fuel is considered, which helps to investigate the spectral characteristics of diesel fuel. Basic wavelet transformations are given. IR spectroscopy of diesel fuel from different producing countries was carried out, and determination of the cetane number through wavelet coefficients and determining conclusion diesel fuel quality were performed.
