CASE CEGR Solution | Tier 4 

CEGR Solution 

With cooled exhaust gas recirculation (CEGR), exhaust gases are cooled, blended with fresh air and then returned to the cylinder, lowering combustion temperatures and dramatically reducing NOx.

Particulate matter (PM) levels are then reduced through the use of an after-treatment diesel particulate filter (DPF) system.

The Diesel Particulate Filter (DPF)
The diesel particulate filter collects the PM and needs to be changed at regular intervals. CASE models with CEGR technology are designed so that the DPF is easy to reach and change.
