Notes

edit
  1. ^ Derivative of M11 with updates backported from X series: "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," "The QSG12 incorporates Cummins Xtra-High Pressure Injection (XPI) fuel system, derived from the larger and more powerful QSX15 Tier 4 Final engine. Although scaled down in size for the 12-liter platform, the XPI fuel system retains all the robust, heavy-duty characteristics of the system, " https://www.cummins.com/engines/qsg12-tier-4-finalstage-iv
