Another Way To Do A Regen

I learned something new today:

I was dispatched on a high-value (HV) load. I had just left the shipper and noticed my regen light was on. We aren't supposed to stop while on a HV load, so I called our maintenance line and asked a mechanic if I could hold off on doing a regen until after I delivered (about 100 miles away).

He said I could do a forced regen while driving. Anyone know how this is done?

I'll answer the question in the first "reply" section. Don't cheat by looking at the answer if you think you know how it is done.


The customer who is shipping the freight. This is where the driver will pick up a load and then deliver it to the receiver or consignee.

This is for Freightliner. Not sure about other makes. The mechanic told me to switch the truck into manual mode and drop down to 11th gear. The higher RPM produce enough heat to burn the soot away from the particulate filter. He said the light should go off within 60 miles. It only took 30

Depends on had bad it is. I have to Regen a lot due to idling on the pad. If it really needs it, it will force you to do a parked Regen.

Ideally, the truck should do its regen while driving and while exhaust temps are high enough to perform it. Then you have parked regen and forced regen which requires an external computer hooked up to prompt it.

Sure. Higher RPMs at lower speeds will generate a higher EGT, water and oil temperature. As to Robert and Kearsey's points, it could require you to stay parked for it to be effectively performed. Engine will not be any good if it derates, HV load or not. City driving and increased stop-and-go traffic clogs things up.

My KW does them frequently, usually while parked next to an RV. It does them while driving in traffic which is irritating because as soon as I stop at a stop light. It starts in. There's a button for forced regen which apparently is supposed to work on the go.
