FIELD : petroleum refining industry; production of engine fuels.SUBSTANCE : the invention is pertaining to the field of petroleum refining industry, in particular, to production of engine fuels. Substance : the method provides for carrying out a catalytic cracking of petroleum fractions in presence of platinumzeolite-bearing rare-earth aluminum-silicate catalyst. The used catalyst consists of 5-20 mass % of "Y" zeolite with a molar ratio of silicon oxide to aluminum oxide within 4.5-9.5 and 80-95 mass % of the silica-alumina base in turn consisting of 40-95 mass % of amorphous aluminosilicate and 5-60 mass % of clay, and having a chemical composition, in mass % : aluminum oxide - 4.5-40.0, oxides of rare earths - 0.5-4.0, platinum - 0.0001-0.01, sodium oxide - 0.01-0.5, silicon oxide - the rest. The technical result : increased output of a gasoline fraction.EFFECT : the invention ensures increased output of a gasoline fraction.2 tbl, 8 ex
