Abstract
A selective reduction catalyst includes a catalyst support in which a plurality of through holes partitioned by porous walls are formed in parallel with each other and an active component having a catalytic action and carried by the walls. Inlet portions and outlet portions, adjacent to each other, of the through holes are alternately sealed, and the wall carrying the active component is formed so that a particle-state solid matter ammonium nitrate cannot pass through it. The exhaust gas purifier includes the selective reduction catalyst, a liquid injection nozzle which is provided on the upstream side and can inject urea liquid toward the catalyst, a diesel particulate filter provided at an exhaust pipe on the upstream side, and filter temperature raising means capable of raising the temperature of the diesel particulate filter to a predetermined value or above.
