Cummins Inc. - QSG12 (Tier 4 Final/Stage IV) Diesel Engines

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. As a result, internal loads on the QSG12 are reduced to free up extra power potential, while heat rejection is lowered by over 40 percent compared with engines using cooled EGR.
