Our IT4/EU Stage IIIB engines employ cooled exhaust gas recirculation (EGR) for reducing NOX, and a diesel particulate filter and diesel oxidation catalyst to reduce particulate matter.
Quad-Cool design isolates coolers from engine heat for increased efficiency and durability, and keeps them well protected behind the heavy-duty grille and fan.
Hydraulic-driven variable-speed fan runs only as needed, reducing noise and fuel consumption.
