    摘要： Disclosed is a diesel particulate filter, including a plurality of cells, which are partitioned by porous cell walls and are closed in a staggered manner by plugs at the upstream end of the filter and at the opposite downstream end thereof, wherein a first oxidation catalyst coating layer is formed on the entire surfaces of the cell walls of the cells that are open at the upstream end of the filter, and a second oxidation catalyst coating layer is formed on the surfaces of the cell walls of the cells, which are open at the downstream end of the filter, in the downstream half part of the filter.

    摘要： Disclosed herein is a method of coating a catalyst support, in which a monolithic catalyst support provided therein with a plurality of longitudinally formed channels is quantitatively coated with catalyst slurry applied to post-treatment of exhaust gas, including the steps of: introducing catalyst slurry into a quantitative container whose bottom is vertically moved; moving a catalyst support to the top of a container such that the bottom of the catalyst support and top of the container are horizontally disposed each other; sealing the bottom of the catalyst support and the top of the container from the outside; moving the bottom of the container upward; and applying a vacuum to the channels of the catalyst support.
