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).

The new QSG12 brings a major advantage for Tier 4 Final and Stage IV equipment installations by restoring the envelope size of the QSM11 predecessor, used for Tier 3 and Stage IIIA applications. Higher efficiency air handling and advanced combustion enable the QSG12 to return to the simplicity of a wastegated turbocharger and achieve near-zero emissions without the need for a cooled Exhaust Gas Recirculation (EGR) system.
