摘要： An exhaust emission purifying apparatus has a NOx reduction catalytic converter in an exhaust passage of an engine, for purifying nitrogen oxides in the exhaust gas by reduction with urea aqueous solution; an injection nozzle injecting the urea solution toward an exhaust upstream side of the converter in the exhaust passage; and fins disposed on an exhaust upstream side of an injection position of the urea solution in the injection nozzle, for generating a spiral swirling flow of the gas swirling about a center corresponding to the central axis of an exhaust pipe. The swirling flow generated in the exhaust gas prior to the injection-supply of the urea aqueous solution promotes mixing of the solution with the gas to thereby promote the hydrolysis of the urea solution. And the exhaust gas and ammonia generated from the urea solution are uniformly mixed together.

摘要： The flow of exhaust gas flowing through the SCR muffler becomes good, thus improving the efficiency of purging nitrogen oxide (NOx) contained in exhaust gas. Further, vibrations that are caused by vibrations of the vehicle, exhaust gas, and the like, to which a reducing agent, etc., supplying nozzle is subject, are suppressed or reduced, thus improving the efficiency of an SCR catalyst purging nitrogen oxide (NOx) and the durability of the reducing agent, etc., supplying nozzle. The SCR muffler comprises an SCR catalyst 1 for selectively reducing and purging nitrogen oxide (NOx) contained in exhaust gas; an exhaust pipe 2 that allows the exhaust gas to flow into the SCR catalyst; and a reducing agent, etc., supplying means 3 that supplies a reducing agent or a reducing agent precursor to the exhaust gas. A plate 4 having air holes 5 which disperse and make a flow of the exhaust gas uniform is provided downstream of the reducing agent, etc., supplying means and upstream of the SCR catalyst. The air holes 5 are arranged in only an area greater in diameter than the exhaust pipe and in a staggered fashion so as to form concentric circles. Further, the reducing agent, etc., supplying nozzle 30 as the means 3 is inserted through a plate 40 having air holes 5, and the plate is held in the exhaust pipe.

摘要： A reduction catalyst is disposed in an exhaust passage of an engine. A reducing agent added to the exhaust gas is urged to react with NOx in the exhaust gas, catalyzed by the reduction catalyst. A member for distributing the exhaust gas to which the reducing agent has been added is provided. This member is formed by applying of an axial welding and is disposed in the exhaust passage such that the internal surface of its joining portion is disposed to overhang from the topmost position of the joining portion.
