Cummins’ latest generation of engines ready to meet EPA Tier 4 Final near-zero emissions regulations extend from 49 to 675 hp (37 to 504 kW). New engines on display at ConExpo 2014 will include the QSF3.8 suited for compact equipment and the heavy-duty QSG12 for high-output machines. Tier 4 specialists at Cummins can discuss the successful field test program based on more than 70 machines accumulating many in-service hours. As a result of this extensive testing, Cummins Tier 4 Final engines went into production on January 1 as fully proven platforms. A range of OEM equipment ready to meet Tier 4 Final and Stage IV will be on display at ConExpo, and many of these machines will feature Cummins engines and integrated exhaust aftertreatment, according to the company. In addition to engines, Cummins also plans to showcase some of the first Tier 4 Final-ready power packs in the industry, together with a power rental trailer.
