Abstract: The main regulatory documents governing the use of oxygenate compounds in automotive fuels are considered. It is proposed to use propylene oxide as an effective oxygenate compound for motor gasoline and diesel fuel. According to the classification of regulatory documents, propylene oxide falls into the category of “other oxygenates”. For gasoline, you can use other oxygenates in an amount of not more than 10%, and for diesel fuel the use of oxygenates is not provided, but there is no ban on their use either. There is a positive effect of propylene oxide on the toxicity of gasoline engines and the smoke of diesel engines, as well as a reduction in fuel consumption and an increase in power. The effect of an oxygenate compound, propylene oxide, on the chemical stability of gasoline and diesel fuel, as well as on the corrosivity of gasoline, was studied. The data on the change in Pн, optical density and the amount of propylene oxide during storage in gasoline and diesel fuel, which suggest that propylene oxide helps preserve the original properties of gasoline and diesel fuel, and thereby increases the warranty period of storage of fuels. It was established experimentally that propylene oxide reduces the corrosiveness of motor gasoline, and ethanol, on the contrary, increases it.

Key words: oxygenates propylene oxide chemical stability corrosivity
