METHOD OF CATALYTIC CONVERSION OF EXHAUST GASES IN CYLINDERS OF INTERNAL COMBUSTION ENGINE Russian patent published in 2001 - IPC

FIELD: mechanical engineering; supply systems of internal combustion engines. SUBSTANCE: proposed method of catalytic conversion of exhaust gases by metal reduction-oxidation catalysts comes to use of the following metal oxides added into fuel in form of solution or on entrainers: F₂O₃,ZnO,CuO,Cr₂O₃,MnO₂,NiO. Solutions of reduction-oxidation catalysts are added to fuel at petroleum refining plants. Engine supply device is adjusted to excess air in fuel-air mixture equal to α = 1,05-1,1. EFFECT: improved conversion of exhaust gases.
