The effect of motor transport on air pollution, especially in big cities, is constantly increasing due to the rapid growth of the number of cars, which is accompanied by increased consumption of fuels derived from petroleum. In view of the significant influence of the quality of motor fuels on the indicators of vehicles operation, there is an urgent need to improve it. The aim of this work is to solve the problem of choice and justification of the priority areas to improve the environmental and performance properties of motor fuels. Analysis was carried out on the influence of the chemical content of motor fuels on their environmental and operational properties. The requirements for motor fuel quality based on analytical investigation were formulated. Medium-term and strategic measures for the oil refining industry to improve the quality of motor fuels were justified. A technology of high-quality motor fuel production based on a highly efficient residueless oil refining scheme was developed. A highly effective multifunctional additive for the integrated and rapid improvement of motor fuel quality was developed and comprehensively investigated.

“…It is seen from the data presented that at the same number of carbon atoms alkanes and cycloalkanes give amount of benzo(α)pyrene which is, by the order of magnitude, smaller than that given by benzene. At peak temperature concentrations of carbon and nitrogen oxides formed during the fuel combustion in the engine are maximal and futher decreasing the temperature "freezes" the concentrations of the gases formed [4]. Thus, according to estimates for the formation of nitric oxide from nitrogen and oxygen within the air, when decreasing ,…”

“…This increases the energy consumption for compression and results in loss of engine power. In addition, the low thermal conductivity of carbon deposit leads to an increased temperature of fuel combustion [3,4,7,18,19], which increases the requirements for the anti-knock resistance of the gasoline. Deterioration of heat removal from the combustion chamber due to increased carbonization results in an increase in temperature when exhaust gas is released, which may lead to burnout of exhaust valves.…”

Abstract.The current obstacles to the sustainable development of the vehicle fleet present one of the most serious and complex challenges for technogenic civilization in view of the consumption of rapidly depleting oil and gas resources and the increasing emissions of the products of fuel combustion. The aim of this paper is to study and discuss the impact patterns of the quality of fuel on the environmental and performance characteristics of vehicles and to develop an approach towards improving the quality of fuel as a means of increasing the sustainability of vehicles. The patterns of influence of the chemical composition of the fuel on the temperature conditions in the engine, the emissions of toxic substances and carbon dioxide from the fuel's combustion, the toxicity of the gasoline vapor, carbonization, fuel consumption, engine power and the requirements for a gasoline octane rating have been identified. The use of a fuel additive has been proposed which improves fuel injection in the engines and excludes tarry deposits in the fuel system through the effective detergency and catalyzes the gasification reactions in the engine. The developed fuel additive was shown to have a positive effect by significantly reducing fuel consumption and toxic emissions and improving the performance of vehicles.

The environmental and operational characteristics of motor transport, one of the main consumers of motor fuel and source of toxic emissions, soot, and greenhouse gases, are determined to a large extent by the fuel quality which is characterized by many parameters. Fuel density is one of these parameters and it can serve as an indicator of fuel quality. It has been theoretically substantiated that an increased density of motor fuel has a negative impact both on the environmental and operational characteristics of motor transport. The use of fuels with a high density leads to an increase in carbonization within the engine, adversely affecting the vehicle performance and increasing environmental pollution. A program of technological measures targeted at reducing the density of the fuel used was offered. It includes a solution to the problem posed by changes in the refining capacities ratio and the temperature range of gasoline and diesel fuel boiling, by introducing fuel additives and adding butanes to the gasoline. An environmental tax has been developed which allows oil refineries to have a direct impact on the production of fuels with improved environmental performance, taking into account the need to minimize the density of the fuel within a given category of quality.
