How does the DPF work on a Cummins diesel?
These pollutants build up on the ceramic of the DPF over time. The Cummins DPF is designed to automatically (“passively”) clean itself, during what is called a “regen”. Essentially, a regen is the process of super-heating the DPF so that the built-up particulate matter can cleanly burn off.
Why does my Cummins DPF not start at night?
Additionally, your trucks may face conditions in which the DPF is getting dirty, but is prevented from starting a passive regen. Long haulers typically deal with this while loading/unloading, or while idling the engine all night to keep the cab warm during mandatory breaks.
How does a Regen work on a DPF?
Essentially, a regen is the process of super-heating the DPF so that the built-up particulate matter can cleanly burn off. This process requires sustained heat, which under ideal conditions occurs naturally. For example, a sustained haul, under load, at a maintained rate of speed. Unfortunately, ideal conditions rarely exist in the real world.
What happens if you cant keep your DPF clean?
Bottom line is, if you can’t keep your DPF clean, you are going to have ongoing aftertreatment issues and repairs. The diesel particulate filter captures pollutants before they exit the exhaust stack. These pollutants build up on the ceramic of the DPF over time.
How does the DPF work on an ISC?
The DPF removes the soot or particulate matter from the gas of the exhaust. It does this by adjusting the fuel injection which increases the exhaust temperature causing the soot to burn off, while simultaneously regenerating the filter. Today, the ISC comes with the Cummins 18.7-cfm air compressor as standard.
