Abstract: 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.

Abstract: PURPOSE: A selective catalyst reducing device for an exhausting system of a vehicle is provided to maximize the diffusion of the sprayed particle of reducing agent sprayed through an injector by introducing exhaust gas through swirl formed on the guide unit of a curved pipe. CONSTITUTION: A selective catalyst reducing device for an exhausting system of a vehicle comprises a dozing unit(30) and a guide unit(50). The dozing unit is formed on the curved pipe(11) of an exhaust pipe(10) in the stream direction of exhaust gas from the front of SCR catalyst. The dozing unit sprays reducing agent to the inside of the exhaust pipe. The guide unit makes the flow of exhaust gas form swirl on a plane perpendicular to the spraying direction of reducing agent from the curved pipe. The guide unit guides the exhaust gas to the curved pipe. The guide unit surrounds the dozing unit on the curved pipe and is formed along the curvature of the curved pipe, around the dozing unit.

Abstract: PURPOSE: An exhaust gas after-treatment system is provided to stably purify nitrogen oxide in a diesel particulate filter by adsorbing or emitting hydrocarbon depending on the temperature of exhaust gas. CONSTITUTION: An exhaust gas after-treatment system comprises an oxidation catalyst, a hydrocarbon trap(130), and a diesel particulate filter(140). The oxidation catalyst reacts with toxic materials contained in exhaust gas and removes parts of the toxic materials. The hydrocarbon trap is arranged on the rear end of the oxidation catalyst and adsorbs or emits hydrocarbon depending on the set temperature of exhaust gas. The diesel particulate filter collects particulate matters contained in the exhaust gas and purifies nitrogen oxide using the hydrocarbon contained in the exhaust gas.
