摘要： An object of the invention is to provide an exhaust emission control device capable of favorably dispersing urea water for improved mixing with exhaust gas even if a flow rate of the exhaust gas is increased. An entry end of a mixing pipe is formed with a first opening at a position near an exit side of a particulate filter and is formed with a second opening at a position away from the exit side of the particulate filter and diametrically opposite to the first opening. Arranged in a downstream end of a gas gathering chamber are a first partition which guides all of the flow of exhaust gas from the particulate filter into a one-way swirling flow around the entry end of the mixing pipe, a second partition which divides the flow of the exhaust gas guided by the first partition into two to cause an inner one of the divided swirling flows to tangentially enter into the first opening and a third partition which causes the remaining outer swirling flow to tangentially enter into the second opening.

摘要： An object of the invention is to provide an exhaust emission control device which eliminates the use of a heat-retention structure using heat-insulating material such as glass wool so as to attain substantial lessening in production cost. A discharge end of a gas gathering chamber is connected to an entry end of a mixing pipe so as to encase the entry end of the mixing pipe and close an opened end face in a required spaced-apart relationship. Moreover, a side surface of the entry end of the mixing pipe adjacent to the discharge side of the particulate filter is formed with an opening; and gas guide passages are formed in the gas gathering chamber by guide fins for tangential introduction of all of the exhaust gas from the discharge side of the particulate filter to the opening. An extra space isolated from the gas guide passages is ensured in the gas gathering chamber as a heat-retention chamber surrounding the entry end of the mixing pipe.

摘要： An exhaust system including an exhaust emission control device with a post treatment unit (e.g., a selective reduction catalyst) for depuration of exhaust gas flowing therethrough is disclosed. The exhaust system includes a layout that introduces the exhaust gas into the post-treatment unit through a turnabout. An introductory part encircles an inlet end of the post-treatment unit and receives the exhaust gas through an exhaust inlet port from a direction substantially perpendicular to an axis of the selective reduction catalyst. The introduction part is formed with a first depression cambered away from the inlet end of the selective reduction catalyst and approaching toward the inlet end of the selective reduction catalyst as the first depression extends away from the exhaust inlet port and toward an introduction direction of the exhaust gas, thereby promoting uniformity of the exhaust gas flow entering the post-treatment unit.
