FIELD: chemistry.

SUBSTANCE: invention relates to a lead-free fuel composition which contains: (a) as its basic part a mixture of hydrocarbons in the petrol boiling range and (b) a small amount of a mixture of additives comprising (i) one or more compounds of p-alkoxy-N-alkylaromatic amine of general formula

I,

wherein R¹³ is hydrogen and R¹² is a methyl, ethyl, propyl or butyl group, and (ii) one or more dicyclopentadienes; wherein components (b)(i) and (b)(ii) are present in the additive mixture in ratios ranging from about 1:19 to about 4:3. Also disclosed is a method of increasing the octane number of petrol, which includes adding small amounts of the disclosed additive mixture to the basic part of the petrol mixture. Described is a method of reducing deposits in the inlet valve of an internal combustion engine, which includes burning the disclosed fuel composition in said engine.

EFFECT: use of said additive mixture in a lead-free fuel composition increases the octane number of motor fuel and reduces deposits in the inlet valve of an internal combustion engine by burning the disclosed lead-free fuel composition.
