A computer sensor monitors the DPF and a dashboard indicator light notifies the driver that the regen is taking place, or the DPF is now cleaning. “The DPF Regen contains the heat of the exhaust, adding up to temperatures exceeding 1000 degrees Fahrenheit, so that the filter is depleted of its buildup and returns to proper functioning capabilities.” What Are DPF Regeneration Cycles?Īn active regen cycle is a normal process that takes place as the truck is going down the road. “A regeneration cycle occurs by essentially ‘cooking’ the filter clean again,” says Kyle Nace of Response Equipment Specialists (Kalispell, MT). In doing so the filter can more efficiently capture particles within exhaust gases and more easily pass through the airflow from intake to output, causing less stress on the engine itself. Among other components along the way, the DPF captures many of these particulates, helping eliminate the ‘dirty exhaust’ emanating into the air.Īs an exhaust component that is continually clogging from the perpetual operation of a diesel truck, this filter is built into a system where it essentially cleans itself of the buildup. Each combustion cycle within a diesel engine includes un-burnt components of diesel fuel, carbon, and other particulates that accumulate into visible smoke from the exhaust stacks. The Diesel Particulate Filter (DPF) is an assist in emissions-control included within diesel exhaust systems, to catch the remaining particulates left within the combustion cycle of the diesel engine.
