Now in Ukraine on the diesel fuel (DF) received from products of oil refining and intended for use in high-speed diesel and gas-turbine engines of ground and ship technical equipment, the standard " DSTU 3868-99 operates. Fuel diesel. Specifications ", similar working in Russia of GOST 305-82. In the table some parameters which characterize those or other physical and chemical and operational properties ДТ are resulted. During too time, last 20 years in Europe and in America more and more a wide circulation find alternative vegetable fuel "biodiesel engine" which are a composition of methyl ethers of fat acids of vegetable oils (rapseed, soya, peanuts, palm, etc.) [1]. Now it is known about ten standards on the "biodiesel engine", working in a number of the countries of Europe and the USA. In the table, as an example properties RME (Rapsolmethylester) which physical and chemical properties are reflected in the standard of Germany DIN 51606 [1] are resulted. Apparently on all basic parameters of "biodiesel engine" influencing processes of injection, evaporation, mixing and in the cylinder of diesel engine МERO (methyl ethers rapseed oils) exceed combustions of fuel corresponding parameters DF, that finally finds reflection in course of working process and integrated ecological-economic characteristics.

       The purpose of given article is the scientific substantiation and practical realization of results compaunding МERO and gas condensate (GC) of the Ukrainian deposits, allowing to create binary alternative fuel with parameters (density, viscosity and a superficial tension) identical to parameters DF.
