Exhaust gas recirculation (EGR)
For years already the Hatz 4L42C has been successfully fitted with a
robustly designed exhaust gas recirculation system for fulfillment of the
emission standards in Europe and the USA. To satisfy the current standards,
the 3L43C and 4L43C are also fitted with the proven exhaust emission
technology for NOx reduction.
Diesel particulate filter (DPF)
Exhaust stages 97/68/EC Stage IIIB and EPA Tier 4 final currently in force
require the use of a diesel particulate filter (DPF) with integrated oxidation
catalyst. Hatz has developed a closed filter system with active regeneration
in operation.
