Non-polluting binary vegetable fuel for a diesel municipal transportation

       Economy of energy carriers of an organic origin, rigidity of norms of emissions of harmful substances with the fulfilled gases of diesel engines, and as restrictions of issue of carbon dioxide forces the majority of the countries to search for ways of reduction of dangerous influence engines on an environment.

       Last time to Europe (1,5 million ton per year) gets the increasing distribution restored alternative Fuel "biodiesel engine" (methyl ethers of vegetable oils - МERO- reapseed, soya, sunflower, etc.) Feature of "biodiesel fuel" is its density increased on 8-10 % and ρ and in 2 times kinematic viscosity and ν In comparison with diesel fuel ДТ [1]. It certainly affects processes of injection that mixing in the cylinder of a diesel engine and, in a result, on its integrated ecological-economic parameters. The purpose of the given report is A scientific substantiation and practical realization of results compaunding Мero and gas condensate (GC), Which allow to create binary alternative fuel with parameters (both ρ, ν and a superficial tension σ), identical to properties of diesel fuel [2]. Then, at injection of this fuel in the cylinder of a diesel engine, dynamics of development a fuel torch (speed of distribution of forward front of torch U m , it{him} distance l, time and *964; achievements of walls of the chamber Combustions and a corner of a cone of a torch and *947;) and characteristics разпыления fuel (dispersiveness atomization d 32 and Uniformity His{Its} dispersivenesses) will be close to similar values ДТ, that is, there will be no infringement of working process Because of physical parameters new топлив

       Для максимального приблидения эксплуатационных характеристик бинарного топлива путем оптимизации его состава, были наложены, кроме стандартных величин, (ρ, ν и температура вспышки), дополнительные ограничения на диапазон процентного соотношения МЭРМ и ГК (σ ти динамическая вязкость). Для одной из смесей ДТ и ГК была полученна экспериментальная кривая фракционной разгонки, которая подтверждает теоретические расчеты повышения экономичности работы дизеля на бинарном топливе. В процессе расчетно-экспериментального исследования был определен состав летнего и зимнего бинарного альтернативного топлива, показатели которых идентичны соответствующим дизельным топливам по ГОСТ 3868-99.
