Assessment of environmental-economic effectiveness of multifunctional fuel additives

The quickest solution to the urgent problem of improving the environmental safety and effectiveness of automobile transport operation with minimal expenditure is possible through the application of fuel additives positively affecting the motor fuel properties. The use of multi-functional additives that have a multi-purpose positive impact on fuel properties is the most attractive way. The absence of a method of comparative assessment of different additives makes the use of additives that improve some properties of fuels concurrently impairing other properties possible, or increase toxicity of exhaust gases, or considerably increase the cost of fuel. The aim of this paper is to develop scientific and methodological basis and specific methodology for assessing environmental-economic efficiency of additives to motor fuels. The authors identified the system of factors forming a structure of environmental-economic effect resulting from the application of multifunctional fuel additives, and also developed a method of assessment of environmental-economic efficiency of application of fuel additives, including the steps of integrated assessment of environmental-economic effectiveness and optimization in operational conditions.
