Caterpillar says the new version of the 150-hp Cat C6.6-liter ACERT diesel engine in it's venerable D6N track-type tractor gets improved fuel efficiency while satisfying U.S. EPA Tier 4 Interim, European Union Stage IIIB and Japan MLIT Step 4 emissions standards. The proven Cat Clean Emission Module incorporates a diesel oxidation catalyst, a diesel particulate filter and the Cat Regeneration System, and functions automatically without interrupting the machine’s working cycle.
A new Auto Engine Idle Shutdown timer, an Auto Engine Speed Control and on-demand viscous clutch for the cooling fan contribute to improved D6N fuel savings. And Eco Modes can be activated in Forward or Forward/Reverse settings, offering potential to substantially reduce fuel use even further.
