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.
Ultimate Underhood – Gasoline Particulate Filters
Just like a DPF, a gasoline particulate filter (GPF) traps and stores soot particles in the exhaust stream.
Diesel Particulate Filters
The EPA has lowered diesel fuel sulfur content from 500 ppm (parts per million) to 15 ppm. This new ultra-low sulfur fuel has been available since October 2006. All 2007 and later diesel engines must comply with the new regulations that require the reduction of nitrogen oxide (NOx) and hydrocarbons (HC) by 50% and particulate
