Abstract

The paper presents the results of the analysis on using vegetable oils as fuel for diesel engines. Possibility of using palm oil as alternative fuel is considered. Physicochemical properties of plant oil and the requirements for diesel fuel are given. Changes in physicochemical parameters of composite fuel are investigated. Palm oil is proposed to be used as a biological additive to diesel fuel and organic peroxide - as a reagent. The results of mixing process analysis, taking into account the differences between physical properties of palm oil and diesel fuel characteristics, are presented. The analysis was based on mathematical investigation. The effect of physical properties (density, dynamic viscosity, surface tension) of palm oil on the characteristics of mixing process has been examined. Changes in palm oil density, higher values of surface tension and dynamic viscosity have been observed. It was established that with increased density, surface tension and viscosity of palm oil, the average diameter of the drops increases, which should increase not only the ignition delay period, but also temperature sensitivity to the ignition process. With that the fuel jet dispersion angle and side surface decrease. A conclusion was made that in order to maintain the effectiveness of the diesel engine working cycle when switching to palm oil fuel, there is an obvious need for radical measures to substantially change its structure and fuel feed system. Palm oil is proposed to be used as an additive to diesel fuel and organic peroxide - as a reagent.
