Managing (DPF) Diesel Particulate Filter Regeneration Cycles
The DPF is designed to store the soot and ash, to later burn them off during a regeneration cycle.

Understanding Diesel Exhaust Filters
The Diesel Particulate Filter (DPF) is a ceramic filter that has thousands of tiny channels or honeycomb-shaped openings that trap the soot onto the channel walls and prevent the particulate matter (down to 1 micron) from exiting out the tail pipe.
