How does a Diesel Oxidation Catalyst (DOC) work?
A DOC is a form of “bolt on” technology that uses a chemical process to reduce pollutants in the diesel exhaust into decreased concentrations. They replace mufflers on vehicles, and require no modifications. More specifically, this is a honeycomb type structure that has a large area coated with an active catalyst layer. As carbon monoxide and other gaseous hydrocarbon particles travel along the catalyst, they are oxidized thus reducing pollution.
