What is regeneration and why is it important?
Diesel particulate filters are efficient at collecting PM from diesel exhaust, resulting in a considerable amount of build-up within a few hours of operation. To clean the filter or reduce build-up, it is necessary to oxidize the solid carbon-based PM into gaseous carbon dioxide. This process is called regeneration. It is primarily dependent upon the type of catalyst applied to the diesel particulate filter, exhaust gas temperature and fuel sulfur content.
