Komatsu EGR & DPF and Adblue Problems
Komatsu use EGR and DPF, and in later machines DPF with Adblue. These systems cause a lot of machines to have issues like low power, check engine lights, derates, nu pushing / lifting power low down and so on. Often construction machines have high idle hours and there are lots of issues with blocking DPF and EGR systems and inefficiencies in the Adblue system causing downtime and call outs. On top of that engine life is not what it should be by a long shot.
DPF issues are usually related to EGR issues, and these issues can be be derates, high fuel consumption, turbo issues, no power in the lower rpm range and so on. Adblue systems require constant refilling and on worksites that brings it’s own challenges with contamination and getting the fluid to machines and filling tanks. Reprogramming not only solves most of these issues, with our program and some driver behaviour changes a real fuel saving is very achievable and saves real money. We know from reprogramming D155-7 that fuel economy was at least 15% better and power low down was restored to pre emission level machines.

DPF & Adblue Problems:
On later machines KOMATSU have chosen to use DPF and AdBlue which is causing the same issues as above but less severe. However reprogramming will not only save fuel, it will save on adblue and adblue issues associated with handling adblue in dusty and muddy conditions.
