In a state that exhaust gas is distributed through a distribution hole 26 formed at the base plate 22 by the bent fins 23, the distributing direction is changed by the fins 23 to create a swirl flow. During press molding, each fin 23 is plastically deformed near its base end on the outermost periphery side in the drawing direction without being parted to form a connection portion 27, and the fin 23 is connected at its outer periphery to the base plate 22 by the connection portion 27.

摘要： PROBLEM TO BE SOLVED: To provide an exhaust emission control system of an internal combustion engine which is capable of optimally controlling the injection of a urea water solution based on a constantly accurate exhaust gas temperature by preventing a jet of the urea water solution emitted from an injection nozzle from adhering to a temperature sensor.
SOLUTION: A plurality of fins 20 and flow paths 23 are annularly disposed on a base plate 19 of a fin device 18 arranged in an exhaust passage. The flowing direction of the exhaust gas which has passed the flow paths 23 is varied to generate a swirl flow. Then, according to a target injection volume determined from an exhaust gas temperature, the jet of the urea water solution is emitted to the exhaust gas to be supplied to an SCR catalyst of the downstream side. In a region in a gap E2 corresponding to a portion between the fins circumferentially adjacent and within a fin height E1 in the direction of an exhaust gas flow, an exhaust gas containing a small volume of the urea water solution or no urea water solution invariably exists. By this, a temperature detecting terminal 26a of the temperature sensor for detecting the exhaust gas temperature is positioned in this region.
