Summary:
During storage and transportation, some classes of hydrocarbons in diesel fuel can undergo chemical transformations over time due to ambient temperature, sunlight, and oxygen in the air. As a result of these reactions, there are changes in the composition of the fuel, such as sediment, color change, turbidity, which have a negative effect on the physico-chemical indicators of the fuel. Such a change can cause engine wear and adversely affect engine efficiency, performance, emissions and durability. The main objective of this study is to investigate antioxidant additives to delay the aging process in diesel fuels. The compounds 1,4 dioxane and 3-hydroxy-1-(2-hydroxyphenyl)-3-(4-nitrophenyl)-propan-1-one were selected for this study. UV rays have been used to stimulate the aging process. As a result of research, the use of 1,4-dioxane has significantly improved the chemical stability, density and kinematic viscosity of fuel and its use in diesel fuel has shown greater stabilization potential.
