Mixing equipment for exhaust gases in automobiles

Abstract

The present invention relates to a mixing device for exhaust gas in automobiles, more particularly to a mixing device for exhaust gas capable of increasing the mixing between exhaust gas and reducing agent by making the exhaust gas passing through said mixing device into a double swirl nature. The mixing device for exhaust gas includes: a hollow plate-type flange, a frame member and a diffuser plate, the hollow plate-type flange is arranged on the flow path of exhaust gas; the diameter of the frame member is toward the center of the flange taper; the diffuser plate separates the interior of the flange and diffuses the exhaust gas and reductant injected through the injector.
