MIXER OF SELECTIVE CATALYST REDUCTION DEVICE FOR EXHAUST SYSTEM

摘要

Disclosed is a mixer for a selective catalyst reduction device of an automobile exhaust system. The mixer for a selective catalyst reduction device of an automobile exhaust system is installed in an exhaust pipe between the front end of an SCR catalyst and the rear end of a dosing unit. The mixer comprises multiple cylindrical members arranged concentrically and dividing the flow section of exhaust gas flowing in the exhaust pipe and of a reducing agent sprayed from the dosing unit; and multiple blade members radially coupled to the cylindrical members to make turbulence in the flow of the exhaust gas and the reducing agent.
