Tier 4 Final focus

Cummins will showcase new Tier 4 Final-compliant engines at ConExpo-Con/Agg, including the 63 kW to 98 kW QSF3.8 and 250 kW to 382kW QSG12 models.

The full range of Tier 4 compliant Cummins engines spans from 49 hp (37 kW) to 675 hp (504 kW). The new QSF3.8 is designed for compact equipment, while the heavy-duty QSG12 for high output machines.

Cummins will also showcase some of the first Tier 4 Final ready power packs in the industry, together with a power rental trailer.

Also on show will be the aftertreatment technology that is used to help meet the Tier 4 Final limits. The portfolio includes Selective Catalytic Reduction (SCR) aftertreatment, new Nano Net fuel filters providing exception levels of protection and Variable Geometry Turbocharging (VGT).

Cummins said it would have Tier 4 specialists available on its booth at the show, and added that many of the new machines on display elsewhere at ConExpo-Con/Agg will feature its Tier 4 Final engines.
