DPF regeneration during stop/go

How do you think transit buses do it? If you're in slower traffic, use a lower gear to get higher RPM's. Or maybe try raising RPM's if you're in neutral.

 

We know with Internationals and trucks that are mostly stop and go, like garbage trucks, that stop and go is the hardest on the entire DPF system. Passive regens, (regens that take place during normal driving), aren't too effective either with stop and go type of applications. This leads to faster than normal system plugging and the need for more frequent regens, which can lead to further plugging if the system doesn't get a good chance to get and stay hot. Some trucks have a "Regen Inhibit" switch that will prevent the system from regens during times like you mentioned. All you really have to do is just watch for your DPF warning lights and do a parked regen when the system is requesting it. Call your local dealer with your vin and see if there are any new engine calibrations to improve the aftertreatment operation. These get updated all the time and really do help!
