How often does a truck do a regen?
low temperature regen will start every 150-180 engine hours. Sometimes there will be high temperature regen while vehicle is in motion and DOC outlet temperature will rise up to 1200F. It may take 20-30min. Forced parked regen you can start when dpf is in Zone 1 .
How long should Regen last?
approximately 45 minutes
Just like most other operators that are using our tool for preventative maintenance, this would be the typical experience. Unfortunately, far too often it does not go quite as smoothly. First, as a general rule of thumb, a forced DPF regen should last approximately 45 minutes.
Why does my truck have to regen so often?
Your DPF regenerates because of excessive exhaust soot overwhelming the DPF. Exhaust soot is the product of incomplete combustion, the soot is actually partially burned fuel. There is only one answer to excessive DPF Regeneration: Eliminate or dramatically reduce diesel particulate matter (soot).
Do trucks regen automatically?
When everything is working as it should, regeneration occurs automatically while the vehicle is in motion, unnoticeable to the driver. In cases where the exhaust isn’t hot enough to burn off soot on its own, the vehicle can inject fuel into the DPF, thereby raising the temperature to burn away soot.
What happens if you don’t Regen a truck?
Regeneration, or regen, of the DPF filter, is the process that burns the soot accumulation that is inside the DPF filter. If you can no longer start a regen then you will eventually get stuck in a derate which will then lead to an engine shut down.
Can you drive while doing a regen?
Usually, nothing. The vehicle needs to run at operating temperature during the regeneration, so highway driving is best. Just drive as you normally would. During active regeneration, the exhaust outlet temperature is extremely high.
Does a regen stop on its own?
Will parked regen stop on its own? A parked regen is controlled by your truck’s computer system and only requires the correct conditions to be met. The process should last between 45 minutes to an hour and no longer. If your parked regen takes longer than this or isn’t finishing, something is wrong.
How much fuel does a regen take?
An active regen is triggered automatically by backpressure created by soot buildup in the DPF. The process can take anywhere from 20 to 60 minutes, consuming up to a half gallon of fuel, and can only occur while the truck is moving.
Can you regen while driving?
Your diesel particulate filter, or DPF, undergoes routine passive regen as needed during steady driving. Active regeneration also occurs and happens best during highway driving speeds. The potentially tricky thing about these various kinds of regen is that they require different driving from your vehicle.
Will a regen stop on its own?
How do you know when regen is done?
Wait for the regeneration to start. 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.
