Hitachi Updates ZX670LC-6 and ZX870LC-6 Excavators with Tier 4 Final Engines

The upgraded 463-hp ZX670LC-6 and the 512-hp ZX870LC-6 are powered by fuel-efficient Isuzu Tier 4 Final engines that employ cooled exhaust gas recirculation, a diesel oxidation catalyst and selective catalytic reduction. An improved piston design allows particulate matter to be burned in cylinder, so there’s no need for a diesel particulate filter. Fuel and DEF consumption is equal to or reduced compared to the Tier 4 Interim models.
