FIELD: internal combustion engines. SUBSTANCE: method comes to preparation of fuel mixture with low octane component by taking in atmospheric air, cleaning it in air cleaner, throttling, forming air-fuel mixture and delivering the mixture into engine cylinders. Prior to delivering fuel mixture into engine cylinders, 20-25% ammonia water and fuel mixture are delivered into intake manifold and mixed inside. Ammonia water is delivered in amount of 2.5-2.8% of fuel mass to provide increase in fuel octane number by 0.8. EFFECT: increased antiknock properties of fuel, reduced toxicity of exhaust gases. 1 dwg, 1 tbl
