Abstract:
Disclosed is a mixing structure for spraying and mixing urea water (additive agent) into and with exhaust gas  1  flowing through a communication passage  7  (exhaust flow passage). The mixing structure is provided with a curved portion  11  in the communication passage  7  downstream of a sprayed position of the urea water as well as a depression  12  on an exit side of the curved portion  11  and formed on only one of sides of the curved portion  11  bisected by a plane into plane symmetry.

Claim (Index 2):
The mixing structure as claimed in  claim 1  further comprising a selective reduction catalyst incorporated in the exhaust flow passage and having a property of selectively reacting NO x  with the reducing agent even in the presence of oxygen, and an injector for spraying a reducing agent as additive agent into the exhaust gas upstream of said selective reduction catalyst, the curved portion being provided between said injector and said selective reduction catalyst.
