All engine ratings are certified to the E2 emissions cycle, and meet EPA Tier 2 and IMO Tier 1 reg- ulations. The electronic power station concept creates efficiencies between the control units, unit injectors, instrumenta-tion and displays to perfectly balancepower supply, fuel consumption and ex- haust emissions at any given load. The MaK DEP products feature anultra-clean, HFO capable burning, long- stroke design and compact generator set design and unrivalled load pickup capa- bilities. The design enables customers to achiever longer intervals between service resulting in lowered overall costs of own- ership.
