  • Patent number: 11092053
    Abstract: 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).

  • Publication number: 20200325808
    Abstract: The invention relates to a particulate filter for collecting particulate matter from the exhaust gases of an internal combustion engine, having a canal geometry that evolves along the entire length of the canal, such that: —the perimeter of the cross section of the canal decreases continuously from an open end (310) of the canal (370) as far as a reference cross section (350) of the canal, then increases continuously from the reference cross section as far as a closed end (360) of the canal, and —the surface area of the cross section of the canal decreases monotonously from the open end of the canal as far as the closed end. The closed ends are situated in the body of the filter near the outlet and inlet faces respectively for the inlet and outlet canals of the filter.

  • Patent number: 10774709
    Abstract: The present invention describes a fluid which is suitable for the decontamination of heat engines which can carry out, at the same time, both 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 consisting of producing an oil-in-water type emulsion.
