  The claimed inventions relate to petrochemistry, in particular to additives for lubricating and fuel materials and to a versatile additive-containing fuel for internal combustion engine, diesel fuel and a furnace fuel for furnaces of heat-and-power generating plants and metal melting furnaces. The inventive additive contains 0.1-82% of monoatomic aliphatic saturated C1-C4 alcohol, 0.1-16% of water- and/or alcohol-soluble ammonium salt of saturated monocarboxylic C2-C5 acid and/or 0.1-44% of carbamide and water up to 100%. The fuel contains a mixture of liquid hydrocarbons and the additive dissolved therein. Gasoline, diesel fuel and furnace fuel are used in the form of the liquid hydrocarbon mixture. The additive is embodied in the form of the versatile additive having the above-mentioned composition taken in a quantity raging from 0.000005 to 0.005%. The liquid hydrocarbon mixture is also embodied in the form of a colza oil and/or a diesel fuel and/or a colza oil methyl ether. Said invention makes it possible to reduce a soot deposit formation during the operation of engines, decrease the toxicity of exhaust gases and the wearing of metal components of engine fuel systems by increasing a molar refraction due to formation of a double ion layer in friction pairs.

  所要求的发明涉及石油化学，特别是润滑和燃料材料的添加剂，以及一种用于内燃机的多功能添加剂燃料、柴油燃料和用于热电厂熔炉和金属熔炉的熔炉燃料。本发明的添加剂含有 0.1-82% 的单原子脂肪族饱和 C1-C4 醇、0.1-16% 的饱和 C2-C5 单羧酸的水溶性和/或醇溶性铵盐和/或 0.1-44% 的碳酰胺以及高达 100% 的水。燃料中含有液态碳氢化合物和溶解在其中的添加剂的混合物。汽油、柴油和熔炉燃料均以液态烃混合物的形式使用。添加剂的形式是具有上述成分的多功能添加剂，其用量为 0.000005 至 0.005%。液态碳氢化合物混合物也可以是可乐沙油和/或柴油和/或可乐沙油甲醚。本发明通过在摩擦对中形成双离子层，增加摩尔折射率，从而减少发动机运行过程中形成的烟尘沉积物，降低废气的毒性和发动机燃料系统金属部件的磨损。
