ЗАСТОСУВАННЯ СПИРТО-АЦЕТОНОВИХ РОЗЧИННИКІВ В ЯКОСТІ ДОБАВОК ДО АВТОМОБІЛЬНИХ БЕНЗИНІВ

Abstract

The article considers the influence of alcohol-acetone solvents on the performance properties of motor gasolines in order to be able to use methanol-acetone solvent as an additive to increase the detonation resistance of gasoline. Currently, there are biocompatible gasolines that contain a variety of aliphatic alcohols. Thus, according to DSTU 7687: 2015 in gasoline allowed methanol up to 3%, ethanol up to 10%, isopropyl alcohol up to 12%, isobutyl alcohol up to 15% and a significant amount of other oxygen-containing compounds. When using gasoline with a high end of boiling in internal combustion engines with spark ignition, soot is formed, which adversely affects the operation of the engine and largely depends on the composition of gasoline.The ability of the fuel to form a homogeneous, without detonation combustible mixture. To improve the energy properties of methanol it can be used as a solution with other hydrocarbons The reason of testing is the possibility of using methanol-acetone mixture to improve the performance of biocompatible gasolines, including pumping, evaporation, flammability, flammability, prone to compatibility and toxicity. Starting properties of gasoline, largely depend on the number of fractions that boil within the temperature range from the beginning of distillation to 10% of gasoline distillation, as well as determining the saturated vapor pressure, but in the presence of low-boiling fractions in gasoline, under certain operating conditions, can cause interruptions in the supply of gasoline, which is associated with the formation of steam plugs in the fuel system of engines. In the modern literature there is no analysis and the possibility of using alcohol-acetone solutions as additives to biogasolines in order to improve their performance.
