Abstract: The invention relates to a fluid suited for depollution of exhaust gas, notably in internal-combustion engines, allowing both to perform catalytic reduction of the nitrogen oxides (DeNOx) contained in the exhaust gas and to provide particulate filter (PAF) regeneration aid. The fluid is a homogeneous aqueous solution of a reductant or a reductant precursor for the DeNOx process, and it comprises a metallic additive for catalyzing the oxidation of exhaust gas particles. This metallic additive is a basic metal carbonate soluble in said aqueous solution. The invention also describes the preparation method and the use thereof for the depollution of exhaust gas of internal-combustion engines.

Abstract: The present invention describes a fluid which is suitable for the decontamination of heat engines which can carry out both, at the same time, the catalytic reduction of oxides of nitrogen (NOx) contained in exhaust gases and assist in the regeneration of the particulate filter (PF). The invention also describes several embodiments of said fluid.
