Diesel Particulate Filter Regeneration Frequency

The particulates in the exhaust gases are collected by the Diesel Particulate Filter (DPF). When the filter becomes saturated with particulates, they are incinerated by a regeneration process. The regeneration process increases the exhaust gas temperature, warning the Diesel Oxidation Catalyst (DOC) first, the warning the DPF. The Engine Control Module (ECM) monitors the system with inputs from two Exhaust Gas Temperature (EGT) sensors 1 and 2 and the exhaust differential pressure sensor.
