Cummins QSF2.8 Engine Overivew

QSF2.8 (TIER 4 FINAL/STAGE IV)

BETTER. IN EVERY DIMENSION.

The 2.8-liter QSF delivers performance at 74 hp (55 kW), which is comparable to that provided by larger engines up to 3.6 liters, in an envelope size that’s similar to 2.2-liter engines used at 49 hp (37 kW). High Pressure Common Rail (HPCR) fuel injection, together with full-authority electronic controls and a Cummins wastegated turbocharger, combine to deliver a very impressive peak torque of 221 lb-ft (300 N•m).

This advanced technology enables the QSF2.8 to meet the near-zero emissions standards of Tier 4 Final/Stage IV using only cooled Exhaust Gas Recirculation (EGR) and our proprietary Diesel Oxidation Catalyst (DOC). The same QSF2.8 engine without the DOC meets Tier 3/Stage III emissions regulations for regions where those standards apply.

The DOC is truly “fit and forget” technology – a totally passive system that never needs any form of regeneration as required by a Diesel Particulate Filter (DPF). It also gives equipment designers the flexibility to mount components separately from the exhaust muffler or as part of a combined catalyst-and-muffler unit. Specifically designed for compact 4-cylinder applications, the CCC benefits from Cummins Emission Solutions' vast experience with DOC technology.
