Aftertreatment Temperature Stabilization

[bwake]

This is something that I believe will assist in the cleaning process of those that have equipment in a constant low speed, stop and go environment. Think busses, waste management, neighborhood delivery vans etc. Without the added heat of the "loaded state" of an aftertreatment system, it's most likely not going to be able to keep the soot burning into ash with a passive/active regeneration and face plugging the DPF.
For many applications that are running up and down the highway, it MAY assist if you happen to enter into that environment during a passive regeneration. For the most part, this should all be doing its thing during normal driving conditions where this "keep warm" function will never come on.
If a typical on highway truck is having issues with keeping itself cleaned of soot, you have other issues that need to be addressed. Rawze's videos on EGR tune up will get you headed in the right direction if that is the case.
