摘要： An exhaust emission purifying apparatus has a NO x 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： In order to suppress deposition of constituent of a reducing agent (dissolved matter of the reducing agent) in an exhaust passage of an engine enhancing an elimination rate of NOx even when temperature of an exhaust emission from the engine is low, an exhaust emission purifying apparatus is provided with an injection nozzle (7) that supplies the reducing agent into the exhaust emission on an upstream side of a reduction catalyst (5) in an exhaust pipe (3), the exhaust emission in the exhaust pipe (3) being heated to a temperature equal to or higher than a melting point of the dissolved matter of the reducing agent whereby deposition of the dissolved matter of the reducing agent on an inner wall surface of the exhaust pipe (3) is suppressed to effectively use the supplied reducing agent for catalytic reduction reaction, even when the exhaust emission temperature is lower than the melting point of the dissolved matter of the reducing agent. As a result, NOx in the exhaust emission is turned into harmless components enhancing the elimination rate of NOx.
摘要翻译：为了抑制发动机的排气通路中的还原剂的成分（还原剂的溶解物）的堆积，即使在来自发动机的排气温度较低的情况下，也能够提高NOx的排除率，因此提出了排气净化装置在排气管（3）内的还原催化剂（5）的上游侧的排气排出物中设置有供给还原剂的喷嘴（7），排气管（3）内的排气发热被加热至等于或高于还原剂的溶解物质的熔点的温度，由此抑制了还原剂的溶解物在排气管（3）的内壁表面上的沉积，从而有效地将供应的还原剂用于催化还原反应，即使当废气排放温度低于还原剂溶解物质的熔点时也是如此。结果，废气排放物中的NOx转化为无害成分，提高了NOx的消除率。
