OPTIMIZED STRUCTURE FOR INTEGRATED CATALYTIC MUFFLER

摘要

An optimized structure for an integrated catalytic muffler is provided to purify exhaust gas from an engine and reduce noise when the exhaust gas flows to the rear of a vehicle. The structure includes a case having an inlet and an outlet, and an SCR catalytic unit that is mounted to the case. Particularly, a portion of the SCR catalytic unit is inserted into the case and the remaining portion is exposed out of the case. The SCR catalytic unit is coupled to the case by bolting or clamping. Accordingly, the production cost and weight are reduced, and maintenance and repair are facilitated.
