Cummins Reveals New QSF2.8 at Intermat

Cummins Inc. revealed the new QSF2.8 engine with 49 to 74 hp output at the Intermat show in Paris. The 4-cylinder, 2.8 l engine was displayed with a fully passive Cummins Compact Catalyst aftertreatment system, designed to meet U.S. EPA Tier 4 Final and EU Stage IIIB low-emissions regulations taking effect in 2013.

The QSF2.8 is the smallest engine to be introduced by Cummins for the off-highway industry with full-authority electronic controls driving a High Pressure Common Rail (HPCR) fuel system. This capability brings the premium-performance characteristics associated with larger Cummins engines to compact equipment below 75 hp for the first time.

Cummins electronics drive the HPCR system to enable multiple fuel injection events with over 1600 bar (23,000 psi) pressure capability, achieving cleaner combustion with improved fuel efficiency. All key engine parameters are constantly monitored and engine performance is optimized according to equipment operating conditions.

The Cummins Compact Catalyst aftertreatment has been specifically developed by Cummins for Tier 4 applications as a maintenance-free, “fit and forget” system ideally suited for use in rental equipment. Without the catalyst, the same QSF2.8 base engine meets all other emissions requirements, including Tier 3 and Stage IIIA, to provide a single, global platform for all applications.
