Clean-Sheet Design Ready For Tier 4 Final And Stage IV Near-Zero Emissions
COLUMBUS, Ind. (Jan. 29, 2013) – Cummins Inc. (NYSE: CMI) today announced the introduction of the QSF3.8 engine with a power range extending from 85 to 132 hp (63-98 kW) ready to meet EPA Tier 4 Final and EU Stage IV near-zero emissions standards. The all-new 4-cylinder, 3.8-liter platform with full-authority electronic controls and High Pressure Common Rail (HPCR) fuel system will be revealed for the first time at the BAUMA show taking place in Munich, on April 15-21, 2013.
The QSF3.8 is designed as a fully integrated air-intake to exhaust aftertreatment system supplied as a drop-in installation for all types of compact construction and materials handling equipment. The QSF3.8 utilizes Cooled Exhaust Gas Recirculation (EGR) and the latest Selective Catalytic Reduction (SCR) technology from Cummins Emission Solutions, without the need for a Diesel Particulate Filter (DPF). Near-zero emissions regulations for engines in the QSF3.8 power range take effect in October 2014 for Stage IV and in January 2015 for Tier 4 Final.
With the advantage of a clean-sheet design, the QSF3.8 is able to combine the performance attributes of a compact, highly economic engine with the proven durability associated with Cummins larger QSB4.5 engine. This impressive combination of economy and robustness will set a new benchmark in the compact equipment industry for power productivity and lowest cost of operation.
The QSF3.8 will continue the enviable reputation established by the popular Cummins QSB3.3 at Tier 4 Interim / Stage IIIB. Although larger in displacement and meeting more severe emissions standards, the QSF3.8 achieves fuel efficiency similar to that of the 3.3-liter engine. The 132 hp (98 kW) maximum power of the QSF3.8 exceeds that of the QSB3.3 to reach the highest output in the sub 4-liter engine class. QSF3.8 peak torque is equally impressive, at 360 lb-ft (488 Nm).
A key design focus for the QSF3.8 was to minimize operating costs, with service-free features such as a crankcase ventilation breather requiring no filter element, reducing emissions and ensuring an exceptionally clean engine.
