Diesel Engine SCR and DPF Regen Systems When Used With Diesel Fuel Additives
Peter M Guerra - VP Technology
It has been brought to my attention that there are increasing concerns about the operation of Diesel Engines with SCR & DPF systems when used with quality fuel additives. There are some fuel additives that claim to improve the efficiency of both the DPF and the SCR systems on new trucks, let’s investigate this further.
First, let me briefly define each of these 2 systems:
• DPF (Diesel Particulate Filter) is the technology that incorporates the high tech filtering/regen processes to remove most solid carbon based emissions from fuel exhaust (the regen process is a costly self-cleaning of the system requiring downtime). There are several different filtering methods, and a variety of filtering media employed, but the intended result is constant: less emissions. The actual results vary from 35% effective to over 99% success.
