  • Publication number: 20100024405
    Abstract: The invention relates to an exhaust gas flow equalizer installed in an exhaust manifold and to an exhaust manifold with such an equalizer installed therein. The invention also relates to the manufacture and use of the exhaust gas flow equalizer and the exhaust manifold. The exhaust gas flow equalizer (2) according to the invention includes catalytic corrugated metal plates (2f) placed cross-wise to each other with the corrugation direction of their folds being in an angle towards the average flow direction of the exhaust gas (G) for equalizing the exhaust gas flow at least in the lateral direction.

  • Publication number: 20090320456
    Abstract: The invention relates to an apparatus for treating diesel exhaust gases including a diesel particulate filter. The invention also relates to a method for manufacturing and using such an apparatus. A particulate filter (DFP) according to the invention has a coating, there is used a sol having the average particle size of the particles below 100 nm, preferably below 50 nm and that a particulate oxidation and that a particulate oxidation catalyst (POC) has been connected in front of the particulate filter in relation to the flow direction of the exhaust gas, which includes at least partially open channels for leading the exhaust gas.

  • Patent number: 6258328
    Abstract: The present invention relates to a catalyst comprising a honeycomb (1) and a surrounding jacket, the honeycomb comprising a structure formed of a stack of metal sheets, of which at least part are profiled, and the honeycomb structure including several through-flow channels for gas. The free ends of the said metal sheets are distributed over a part (S1) of the honeycomb periphery unsymmetrically to the center of the honeycomb so that part (F1) of the honeycomb's periphery is free from the free ends of the metal sheets. The said honeycomb is attached either directly or through an intermediate layer to the said jacket over an area (L1) comprising at least part of the said free ends.
