DPF failure is the industry standard, but it doesn’t have to be

Mar 20, 2017

Today’s modern, emission equipped engines promise more efficiency. However, the reality is that constant DPF failure and repairs negate any potential efficiency gains. Fleets across the country are throwing away thousands of dollars every month trying to keep up with maintenance and repair costs, but that no longer has to be the case.

What is premature DPF failure?

According to Cummins, a DPF should last 5,000 hours (approximately 225,000 miles) before needing maintenance. Most fleets are lucky if they get half of that out of a DPF. If you are not getting at least 5,000 hours out of your DPF before needing to clean it, then you are experiencing premature failure. Premature DPF failure occurs because of having poor regen effectiveness.

What is regen effectiveness?

In order to effectively clean the DPF, a regen must reach the right temperatures for the right amount of time. The ability to regen effectively is partially controlled by the ECM. Most trucks have generic, dealer settings installed in their ECM’s, which make it almost impossible for the truck to execute a proper regen on a consistent basis. Every truck should have their ECM set properly for its’ duty cycle to allow for maximum regen effectiveness. Your DPF will last longer if regens are working properly. Here is an example of how proper ECM calibrations with LDT Duty Cycle Programming can lead to more consistent, effective regens:

This is just a small snap-shot of what makes for an effective regen. “Before” the ECM was set-up correctly, it was only achieving an effective Intake Temperature 60% of attempts. “After” correct adjustments were made with LDT Duty Cycle Programming, temperatures were effective 100% of regen attempts. This means that the DPF can stay cleaner, longer.

Stop Losing Money on Repairs

Every mile your truck drives with a dirty DPF is contributing to progressive damage. This is evident by poor fuel economy, power loss, acceleration/pull lag, check engine lights, and eventually complete breakdown. Keeping your DPF clean will prevent expensive repairs, and save you thousands.

With LDT Duty Cycle Programming, your trucks’ ECMs will finally be set-up to allow the entire Aftertreatment system to work properly. Regens will occur when they need to, at the right temperatures, to keep the DPF cleaner, for longer. LDT Duty Cycle Programming is the first step towards having an efficient and reliable fleet.
