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.
Why does Regen light flash when truck is parked?
It means that the exhaust is at high temperature due to extra regen speed which occurs when the truck is traveling at low rates or is parked. If this lamp flashes it means that parked regen is in progress and that system temperature is not up to par yet.
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.
How does the Regen cycle in a DPF filter work?
“A regeneration cycle occurs by essentially ‘cooking’ the filter clean again,” says Kyle Nace of Response Equipment Specialists (Kalispell, MT). “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.”
How to reset / regenerate / clear your DPF warning light?
It’s at this point the warning light will come on and your intervention is required. How to clean, clear and reset (regenerate) the system. You should drive your vehicle for approximately 15 minutes keeping the engine revs between 2000 – 2500 rpm.
What’s the best way to reset a check engine light?
In such a case, it is highly recommended to check the codes with a scanner instead. Switching the ignition on and off is also one method of hard reset without disconnecting batteries. Put the keys in your ignition and turn your ignition on and off consecutively after a second in each step.
What to do when your car starts a DPF Regen cycle?
If the car starts a DPF regeneration, extend your journey if need be until it has finished the job (takes around 5-10 mins of driving, in my Alfa at least), and give it some beans to help it out.
What causes incomplete DPF regeneration in an engine?
The single biggest cause of incomplete DPF regeneration is the duty cycle of the vehicle. Engines need to achieve extended periods of high temperature, high RPM activity in order to complete a DPF regeneration.
Where does the DPF Regen cycle take place?
First time diesel owners often think there is something wrong with their trucks, but the DPF regen is a normal, often recurring, requirement included with diesel ownership. A forced regeneration cycle is a manual process that takes place at the diesel shop with a certified technician initiating the cleaning of the DPF.
Where does the forced Regen cycle take place?
A forced regeneration cycle is a manual process that takes place at the diesel shop with a certified technician initiating the cleaning of the DPF. “We force the truck’s computer to initiate the process prior to the parameter requests that happen with the active regen,” says Nace.
