EXHAUST GAS PIPE FOR REDUCTANT DOSING

摘要

The present invention relates to an exhaust pipe for injecting a reducing agent. According to an embodiment of the present invention, an exhaust pipe for injecting a reducing agent (100) is formed with a curvature pipe as an inlet and an outlet are connected by a curvature unit (110). An adapter (120) is formed in the curvature unit (110). A dosing module (140) is installed in the adapter (120). As the dosing module (140) injects a reducing agent toward the outlet, a reducing agent and exhaust gas are thoroughly mixed. Moreover, according to an embodiment of the present invention, the exhaust pipe for injecting a reducing agent can reduce a heat transfer area as the surroundings of an installation hole (122) is formed to be a protruding surface (128) to protrude in a cross section of the adapter, thereby reducing heat transfer of a high temperature of exhaust gas to the dosing module (140).
