The process uses high temperatures in the Diesel Particulate Filter (DPF) in order to facilitate the chemical reaction.Refer to Operation and Maintenance Manual, "Diesel Particulate Filter Regeneration" for an overview of the CRS operation. This article explains how the system works in all Cat machines.The default regeneration mode at start-up is set for automatic regeneration. In the automatic mode the regeneration system on the engine will trigger regeneration when regeneration is appropriate. The operator may override the automatic regeneration cycle if needed.
