Subsequent regeneration procedures that are carried out with excessively high levels of carbon soot deposit can lead to overheating and damage to the particulate filter. A forced DPF regen will ensure that any soot buildup in the DPF / SCR System is removed. The tractor comes with a soot level indicator on the display, and an automatic exhaust filer cleaning system. In reality, however, the DPF-related increase in fuel consumption may be greater, as all of these studies fail to consider the additional increase in exhaust flow restriction and regeneration . 1)Clean Filter lamp illuminates. The SCR uses Diesel Exhaust Fluid to reduce the levels of NOx in the engine exhaust. A forced DPF regen is performed when a diagnostic scan tool, such as the OTR Reset Tool, starts the regen process. The DPF Soot Load Reduction Threshold is the level at which soot is released into the air during regeneration. The ATS will periodically clean (regenerate) the DPF. Beginning with 2017 Silverado and Sierra models, the DPF Soot Accumulation is measured in percent instead of grams in GDS 2. This is necessary to prevent a regenerative cycle from occurring. This is a good practice because soot can buildup on the face of the DOC substrate and also restrict exhaust gas flow. The most common form is passive regeneration. This process involves burning the blocked soot at a high temperature to leave only a tiny ash residue. Passive regeneration happens frequently in long-haul trucking because it requires continuous driving where the DPF can hit a temperature above 1,000 degrees Fahrenheit to create the heat levels that turn soot into ash. is reduced every time the DPF is at a sufficiently high temperature for a period of time. The soot reduction also means clean EGR valves . Parked Regeneration Once the soot level reaches 110%, the operator can initiate a parked regeneration.
