Why is my diesel particulate filter clogged?
Why is my diesel particulate filter clogged?
If the EGR system is failing, with improper recirculation of the exhaust, the truck runs with a lot more particulate and a lot more soot, therefore also clogging the DPF even more. “The entire system relies on the engine running well and doing everything possible to avoid repair or replacement of the DPF,” says Kyle.
What happens during a Regen cycle on a diesel truck?
An active regen cycle is a normal process that takes place as the truck is going down the road. 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. “You’ll notice a reduction in power during a regen,” notes Nace.
Is the diesel particulate filter part of the exhaust?
The Diesel Particulate Filter (DPF) is part of your exhaust and controls the ‘soot’ that would otherwise be expelled from the system. You may have noticed that modern diesels no longer leave you in a cloud of smelly black smoke when they accelerate off. The filter…
What happens if the Regen cycle is not completed?
If the DPF regen cycle is not taking place, or not completing a full cycle, a ‘check engine’ light might illuminate on your dash. In doing so the many sensors in the system will calculate the particulates prior to the DPF and post, recognizing a lack in operation of the DPF.
Can a diesel particulate filter get clogged?

We all know by now that the mandated 2007 and 2010 emissions standard rules radically changed on-highway diesel-powered trucks and tractors.
What to do if your diesel exhaust is blocked?
If you are driving slowly everywhere in your large diesel, the DPF will become blocked. Increase your speed and plant your foot to floor to when accelerating to increase exhaust temperature and clear soot levels. Increase Your RPM.
When does passive regeneration of exhaust take place?
Passive will take place once the exhaust reaches optimum temperatures where the regeneration will automatically begin. The exhaust will reach these temperatures will occur mostly on prolonged highway driving.
An active regen cycle is a normal process that takes place as the truck is going down the road. 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. “You’ll notice a reduction in power during a regen,” notes Nace.
