Model DOC -Flow-Through Diesel Oxidation Catalyst

The diesel oxidation catalyst (DOC), or Two-Way, owes its name to its ability to promote oxidation of several exhaust gas components by oxygen, which is present in ample quantities in diesel exhaust. When passed over an oxidation catalyst, the following diesel pollutants can be oxidized to harmless products, and thus can be controlled using the DOC: Carbon monoxide (CO), gas phase hydrocarbons (HC), organic fraction of diesel particulates (SOF). Additional benefits of the DOC include oxidation of several non-regulated, HC-derived emissions, such as aldehydes or PAHs, as well as reduction or elimination of the odor of diesel exhaust.
