Background
Fleet operators often face challenges in maintaining Diesel Particulate Filters (DPFs), particularly in managing soot levels to prevent parked and forced regenerations (regens). Regens are procedures initiated when the DPF accumulates excessive soot, requiring immediate maintenance procedures, resulting in operational downtime and increased costs.
objective
To demonstrate the effectiveness of DF5 in reducing NOx and soot accumulation in DPFs, thereby minimizing the need for forced and parked regens.
Methodology
To demonstrate the effectiveness of DF5 in reducing NOx and soot accumulation in DPFs, thereby minimizing the need for forced and parked regens.
Test Vehicles: 2016 International ProStars with Cummins ISX15 15-Liter engines. Duration: 1,000 miles of testing with and without DF5. Metrics Monitored: NOx emissions at the intake and exhaust stages, Soot load on DPFs, and the frequency of regeneration cycles.
Results
NOx Emissions Reduction: At the exhaust stage, there was a significant drop in NOx emissions, ranging from 73.62% to 89.84%.
At the intake stage, NOx emissions saw a decrease ranging from 10.71% to 7.61%.

Reduction in Soot Load
The use of DF5 resulted in a relative decrease in soot load on the DPF ranging from 13.46% to 31.82%. This significant reduction directly correlated with a decreased need for forced regens.
Decreased Frequency of Regenerations
With lower soot accumulation, the frequency of parked and forced regens was substantially reduced. This led to minimized operational downtime and decreased fuel and DEF consumption.
CONCLUSION
This case study confirms that the reduction in soot load and consequent decrease in forced and parked regens illustrate DF5’s value in fleet operations, extending the longevity and efficiency of DPF’s. By reducing the frequency of regenerations, DF5 offers an economically advantageous solution, leading to savings in both downtime and operational costs. Regular use of DF5 maintains cleaner DPF’s ensuring better exhaust flow efficiency while reducing emissions.
