摘要： The present invention relates to an installation for depollution of the exhaust gas circulating in an exhaust line (10), notably from an internal-combustion engine, comprising at least one catalysis means for selective catalytic reduction of nitrogen oxides (NOx), at least one particle elimination means, a main tank (26) comprising at least one particle reducing agent and means (20) for feeding the reducing agent into the exhaust line.
According to the invention, the installation comprises reducing agent additivation means (30).

摘要： The present invention describes a fluid which is suitable for the decontamination of heat engines which can carry out both the catalytic reduction of oxides of nitrogen (NOx) contained in exhaust gases and assist in the regeneration of the particulate filter (PF), said fluid being in the form of a stable suspension of colloidal particles, these colloidal particles being dispersed in an aqueous solution containing at least one reducing agent or at least one precursor of a reducing agent for NOx. The invention also describes several embodiments for the preparation of said fluid.
