Doing A Parked Regen Before It's Needed

Parked regen once a week? Seems quite excessive. It should be able to do a passive regen as you're driving on highway.

 

What's the recommended? Something like minimum 45mph for an hour to burn 'er clean?

 

These DPFs like high exhaust temps to burn them clean ie pulling hills with a heavy load in trailer

 

In my manual it says you can't do regeneration unless you get a light.

 

You would need the engines diagnostic software to do a forced regen.

 

What kind of engine do you have, Cummins or detroit and what year is the unit.?

 

You can push the manual regen button if it takes great if not the computer will not allow it because it is not needed. Doing a regen will NOT hurt the motor

 

Couple of things. Make sure your engine is programmed to allow a regen during while in PTO mode, or when increasing the idle speed while sitting. If you are running your engine while stopped, increase the rpm and it will allow a regen to happen while parked automatically if needed. Generally the warning light comes on when you are about 80% plugged, but the system will start one on its own around 60%. So make sure it is programmed to allow this. I don't know about your truck, but some Internationals do have feature options where you can initiate a regen at a much lower soot loading for the exact reason you are asking about. This is also something you can ask about.
