Tier 4 Final
HPCR, EXTERNAL CEGR WITH DOC & SCR
Why this solution: As an after-treatment system, Selective Catalytic Reduction (SCR) lowers exhaust temperatures and does not require unproductive fuel use associated with burning off particulate matter, plus there’s no Diesel Particulate Filter (DPF) to replace making it a great solution for larger, high-productivity engines.
How it works: The high-pressure common rail (HPCR) system electronically controls fuel injection for greater fuel economy through more efficient fuel burn. With Cooled Exhaust Gas Recirculation (CEGR), exhaust gases are cooled, blended with fresh air and then returned to the cylinder. Then the Diesel Oxidation Catalyst (DOC) oxidizes the machine’s exhaust to create heat, further managing particulate matter emissions.
SCR is a simple solution that combines DEF (Diesel Exhaust Fluid) with exhaust to convert NOx emissions into nitrogen and water. DEF is a non-toxic liquid that reacts with engine exhaust in the presence of a catalyst to perform emissions conversion.
What this means to you: SCR provides a significant reduction in fuel use and has no DPF to replace, resulting in a lower total operating cost for the life of the machine. Keeping it running is simple - just refill DEF as needed.
