  2. Utilize Cummins Aftertreatment DPF Temperature Stabilization Feature to reduce DPF failure
  3. This simple solution is LEGAL and will improve reliability and efficiency instantly

If your fleet is suffering from DPF failure and other emission system related issues, then keep reading to learn how simple and quick it is to improve your Cummins engine. DPF failure and aftertreatment failure no longer has to cripple your maintenance and repair budget. DPF issues no longer have to put your trucks down for weeks at a time at the dealership.

Cummins Features and Parameters

Straight from the Cummins Insite training manual

Premature DPF failure is the most common issue for modern, emission compliant fleets. Fleets are being told to upgrade and improve their fleets with the latest and greatest in engine technology and telematics. However, these expensive new trucks still suffer from basic and preventable DPF failure. What fleet owners aren’t being told is that DPF failure can be easily and legally prevented with a few simple changes to maintenance.

If you own an emission compliant Cummins, then congratulations on a great choice. Of all the engine manufacturers, Cummins does the best to provide owners the ability to truly control the efficiency of their fleet. This is done through “owner accessible features and parameters”. Cummins features and parameters are accessible through the ECM, utilizing Cummins’ software, Insite. These features and parameters allow an owner to customize the way the aftertreatment system works. It allows you to maximize aftertreatment efficiency according to the specific duty cycle of the truck. While this should have been done by your Dealership or service center, the sad reality is that most don’t know how to do it properly, or don’t want to do it. If you want to take back control of your fleet, it starts by utilizing Cummins’ features and parameters to improve your DPF efficiency and the overall reliability of your fleet.

Enabling the correct features and parameters is critical because just about 90% of new trucks come with generic factory ECM programming.

In other words, it is likely set up for typical over-the-road use, without consideration for idle time, route, average speed, or other important factors which impact the DPF and aftertreatment system. This can be detrimental even in an OTR duty cycle, but is completely disastrous in a vocational application.

It is important to understand that you should only adjust Cummins owner accessible features and parameters in accordance with manufacturer guidelines. Additionally, only use licensed Cummins software, Insite, to make any changes. Not following manufacturer recommendations or guidelines can damage your truck and void your warranty. Using “hacked” software or non-licensed software to access the ECM can void your warranty and may be illegal. 

Cummins Technical Service Bulletin:

Aftertreatment Diesel Particulate Filter (DPF) Temperature Stabilization Feature

Are you wondering what we mean by adjusting Cummins features and parameters? There are many different adjustments to be made and features that can be enabled depending on your fleet utilization. However, one of the most common issues we see can be easily corrected with one simple feature: Aftertreatment DPF Temperature Stabilization. Below are excerpts taken directly from a Cummins Technical Service Bulletin that recommends this feature.

Symptom:
Frequent need for stationary regeneration or excessive regeneration in low duty cycle or
stop/go applications, such as refuse truck, feedlot truck, school bus, shuttle/transit bus,
delivery truck, yard spotter, mixer, utility truck and so forth.

IF THIS SOUNDS LIKE A PROBLEM YOUR FLEET IS EXPERIENCING, THEN KEEP READING!!!

As you can see, this is a very broad sweeping and common symptom that many fleets are dealing with. Particularly in the vocational application. While dealerships and service centers may have you believing that fixing this is very complicated, Cummins features and parameters actually provide a very simple solution with the Temperature Stabilization feature.

According to the Cummins Technical Service Bulletin, here is the “why” behind the issue:

Root Cause:
With the Aftertreatment Diesel Particulate Filter Temperature Stabilization feature disabled, active regeneration of the aftertreatment diesel particulate filter (DPF) is inhibited…

If you have been reading any of our articles, or have even some basic experience in dealing with DPF issues, then you well know that regens are the problem. If the system can’t regen, the DPF will plug and fail. What Cummins is saying here is that WITHOUT this feature being enabled, ACTIVE REGEN IS INHIBITED!! Now why would anyone NOT enable this feature, given this information?

Major DPF Problems, Easy Fix

Cummins has described a very common, and very serious issue that many fleets are dealing with: “frequent need for stationary regeneration, or excessive regeneration“. Especially in the vocational application. They released an update and easy directives to follow to help correct the problem: the Aftertreatment DPF Temperature Stabilization feature.

Here is the “how” behind the fix:

Resolution:
The Aftertreatment Diesel Particulate Filter Temperature Stabilization feature has been released to improve the ability for low duty cycle and stop/go applications to actively regenerate the aftertreatment DPF during normal operation.
The Aftertreatment Diesel Particulate Filter Temperature Stabilization feature is a user-selectable feature in INSITE electronic service tool. See Figure 1.
The Aftertreatment Diesel Particulate Filter Temperature Stabilization feature will also allow the system to inject low amounts of fuel to keep the aftertreatment DPF warm when the vehicle speed drops below the Minimum Vehicle Speed threshold. This prevents the regeneration from aborting and allows the regeneration to continue once the vehicle speed exceeds the Minimum Vehicle Speed threshold.

Essentially, this feature allows the aftertreatment system to work as designed to keep the DPF clean through regens. If this feature is not enabled then your truck can’t regen properly, and the DPF can’t stay clean.
