What does soot level high mean?
When the diesel particulate filter warning light turns on it means that the soot level from the diesel exhaust is high and your vehicle is likely to go into limp mode.
How does a regen work?
A forced regen occurs when soot builds up inside the diesel particulate filter (DPF) to the point that the vehicle is no longer operable. When this happens, a driver has to pull over and initiate a self-cleaning process that can take up to 40 minutes — valuable time that could have been spent on the road.
What is exhaust regeneration?
Regeneration is the process of incinerating the soot that has collected in the soot filter. High heat burns the particulate matter and turns it into ash — which means the soot filter will eventually require cleaning as a normal maintenance requirement when regeneration will no longer clear the system completely.
How many grams of soot should be in a DPF?
In other words, the amount of ash equals the amount of soot at the maximum allowable soot load limit of 6 g/L. Further, after 150,000 miles (241,000 km) of operation—equivalent to the minimum EPA ash cleaning interval—ash comprises over 80% of the material trapped in the DPF, with the minority being soot.
Can ash be removed from DPF?
In addition to the service interval, the specific cleaning methods applied to the filter depend largely on the location and type of ash deposits as well as the amount of residual soot in the DPF. Although the soot can easily be removed through regeneration, removal of the ash requires specialized cleaning processes.
How do I know when regen is done?
Monitor the Exhaust temperature and RPM. When the idle comes back down it means that the regen has finished. If the regen starts and stops then you may have a problem that prevents the regen from taking place.
What’s new at DCAT?

Does DPF regeneration add to the complexity of your machine?
Don’t let DPF regeneration add to a machine’s complexity. Instead: Look for systems that are “transparent”: That means regeneration happens in the background with no operator interaction.
When do I need to renew my DCAT membership for 2022?
Membership dues for DCAT’s fiscal year 2022 must be received by October 31, 2021. Renewal information was sent to designated contacts at DCAT member companies beginning in August.” The DCAT organization is pleased to welcome our Member Companies back to New York City for DCAT Week on March 21-24, 2022!
What is the lifespan of reticulocytes in cats?
In cats, aggregate reticulocytes mature into punctate reticulocytes within 12-24 hours; punctate reticulocyte have a lifespan of around 7 days (and can persist for up to 21 days) before all the RNA is lost.
