Abstract
The paper discusses an actual scientific and practical problem of expanding the fuel base of the transport means by using biodiesel fuel in the form of ethyl esters made of rapeseed, sunflower and soybean oils. The choice of the optimal blend composition of diesel and biodiesel in appropriate operating conditions helps to provide the energy independence of transport companies on mineral hydrocarbons, reduce the anthropogenic influence on the environment and improve the environmental safety of transport. The research offers a new technological model for the production of biodiesel, which improves the quality and reduces the cost of biodiesel, reduces its negative impact on the elements of the vehicle fuel system. Reliability of fuel system elements is calculated. Mathematical expressions were obtained to determine the probability of failure-free operation of the fuel system and the probability of failure of its elements during operation at various fuel mixes. The assessment of the economic efficiency of the use of biodiesel as a fuel for vehicles was made.

The paper discusses an actual scientific and practical problem of expanding the fuel base of the transport means by using biodiesel fuel in the form of ethyl esters made of rapeseed, sunflower and soybean oils
Since most of the transport work in the agriculture and transport industry is conducted by trucks, much of which are equipped with diesel engines [2], the issue of energy optimization of the operating vehicles and increasing their environmental safety when using biodiesel fuel is relevant
The concusions of our study are the following: 1. The source analysis showes that the operation vehicles on diesel oils based on veget methyl esters of vegetable oils and their mixtures makes possible a reduction in the smoke of exhaust gases and the content of products of incomplete combustion of fuel, which leads to a reduction of the environmental pollution
Summary
In anticipation of the expected shortage of mineral hydrocarbons, the development of alternative energy proceeds to a global scale. The tendency of searching for renewable resources is aimed at energetic and economic independence from the import of petroleum products, which is currently the primary task for our country. An important direction in the implementation of unconventional energy resources is the environmental aspect, contributing to the reduction of anthropogenic impact on the atmosphere by reducing emissions of harmful substances. According to the State Statistics Service of Ukraine, the main consumer of light petroleum products is the agricultural sector (27.8% of total consumption) and transport (26.9%) [1]. Based on these indicators, the use of alternative fuels in vehicles would help to solve the problems discussed above. Since most of the transport work in the agriculture and transport industry is conducted by trucks, much of which are equipped with diesel engines [2], the issue of energy optimization of the operating vehicles and increasing their environmental safety when using biodiesel fuel is relevant
