A method is described for reducing the vapor pressure of a mixture of motor fuels based on C-hydrocarbons containing from 0.1 to 20% by volume ethanol for conventional internal combustion engines with spark ignition, where, in addition to the ethanol component (b) and the C-Carbon component (a ) an oxygen-containing additive (c) selected from at least one of the following types of compounds: alcohol other than ethanol, ketone, ether, ester, hydroxyketone, ketone ester, and a heterocyclic oxygen-containing compound is used I am in the fuel mixture, in an amount of at least 0.05 of the total fuel volume. A mixture of ethanol fuel (b) and an oxygen-containing additive (c) that can be used in the method of the present invention is also described. |
