A diesel oxidation catalyst cleaning (DOC) is a device that breaks down the pollutants from a diesel engine in the exhaust stream by using a chemical process aimed at turning the pollutants into less harmful components. It tends to closely resemble an automobile’s catalyst converter. Like a Diesel particulate filter, the diesel oxidation catalyst will eventually become blocked as they do their job by capturing the harmful substances. The honeycomb holes that are in the catalyst converter are being filled by hydrocarbons and other substances.
