Cummins Power Generation Releases Tier 4 Gensets For Mobile Rental Market
Cummins’ certified Tier 4 Final QSB7 and QSL9 engine platforms form the basis for mobile sets that meet EPA regulations.
U.S. EPA Tier 4 Final certified mobile generator sets with 150 kW to 275 kW power outputs are now available from Cummins Power Generation for the rental market. Cummins conducted extensive field research to develop a reliable, easy to operate and versatile product to meet the latest emissions regulations. The mobile generators have been thoroughly validated and are now available to rental operators and customers.
The new units are based on the Cummins QSB7 and QSL9 engine platforms that have undergone extensive refinements to meet the stringent EPA Tier 4 Final regulations. Cummins was able to meet the new Tier 4 Final regulations through a combination of in-cylinder engine improvements, exhaust gas recirculation (EGR), selective catalytic reduction (SCR) exhaust aftertreatment and diesel oxidation catalyst (DOC). Due to the success of the in-cylinder combustion improvements, these engines do not require the use of a diesel particulate filter (DPF) to meet the new air quality standards. The simpler SCR-only solution helps reduce maintenance overhead and service costs.
