Abstract: Due to the stringent requirements imposed on diesel fuel, the authors of this paper proposed a method to improve environmental and performance properties of diesel fuels. The paper presents the results of the study of naturally occurring glycerides as detergent-dispersant additives for diesel fuels. The authors have developed a rapid method of determining the effectiveness of antioxidant additives for fuels and lubricants, which is based on the measurement of the optical density of the sample during oxidation in the given experimental conditions. A rapid method of evaluating the detergent-dispersant properties of the fuel based on the determination of the changes of optical density during sedimentation of the pollutant model based on colloidal graphite of grade P-1 (1 wt. % strong). The results showed that the designed additive shows unique surfactant properties at concentrations of 0,001–0,005 % by weight. The additive improves both thermal-oxidative, detergent-dispersant and environmental performance of fuels, because additive molecules contain optimally combined functional groups which creates internal synergies.
