Regen AGAIN :-(

you cannot compare trucks, but maybe driving/idling habits...

maybe he idles LESS than you do.??

maybe his filter had been baked long ago.>???

you could have 300 trucks, and 400 drivers, no 2 will be exact in the truck nor drivers.....

 

If you Regen more frequently, and it won't stay in it longer than 15 min, than you need to bake the dpf. It'll repeatedly require regens. To reduce regens, don't idle as much, and use your cruise control instead of driving with your feet to the pedal.

 

Regen is done to clean the soot out of the DPF. So basically it could be 2 things. Either your truck is producing more soot, or the DPF differential pressure sensors are reading incorrectly, telling the ECM the DPF needs a regen.

Building off my first point: It is definitely possible its time for a DPF cleaning. Over time ash builds up and reduces the DPF's soot capacity. Less capacity = more frequent regens.

 

What truck? Does yours have a soot gauge? My 2015 Volvo does. I'm only 20k into ownership but it hasn't done one yet (in a month).

 

After 9 months at this company, and I am in a Mack, mine has requested 1, and that was when I was having injector issues. And over the last few months, my idle percentage is in the 70% range. Regens, if everything is working right, should be done while moving (passive regen). If you're doing a parked that often, something is amiss.

 

Is regen switch set on off/auto/manual mode? If so, make sure its set in the middle position-auto regen, while youre driving it should be doing regen. As long as youre rolling 50mph or higher and have a load it should do automatic regen.

 

If it’s a 2010 or later you shouldn’t be doing parked regens unless something is wrong with it or you’re in a sever service application.

 

Manual parked regen is going away DPF may need cleaning. My 2017 truck has 231,580 miles and never needed a Manual parked regen. When I idle the truck, it does automatic parked regen. If needed. It only takes 20 minutes at 1250 RPM. It only happen after 6 hours of idle time. The computers do all the work now. Going down the road it does everything automatic also.

I have the Optimized Idle System. The computers start the engine for heat or a/c and battery charging and engine olo temperature. Detroit S60 had this back in the 90. It back and now the computers also do automatic parked regen if needed
