METHOD AND LEAD-FREE LOW-EMISSION GASOLINE FOR FUELING OF REDUCED-EMISSION MOTOR ENGINE Russian patent published in 2007 - IPC C10L1/04 

FIELD: petroleum processing and petrochemistry.

SUBSTANCE: invention relates to lead-free low-emission gasoline for internal combustion engine and to a method for reducing emissions into atmosphere. Lead-free low-emission gasoline for internal combustion engine is characterized by octane number (R+M)/2 lower than 86.7 and level of sulfur below 40 ppm. Method of reducing emissions of at least one of hydrocarbons, carbon monoxide, and nitrogen oxides out of automobile internal combustion engine comprises: (a) production of lead-free low-emission gasoline, which on burning in engine produces reduced emissions of at least one of hydrocarbons, carbon monoxide, and nitrogen oxides as compared with comparable lead-free gasoline with minimum octane number 87; and (b) fueling of engine with indicated low-emission gasoline. Described is also a method for fueling of automobile engines at reduced total emissions.

EFFECT: considerably reduced emission of hydrocarbons, carbon monoxide, and nitrogen oxides.
