The G Series minimizes engineering requirements for vehicle and equipment manufacturers with a common, compact installation envelope. A key design focus for the G Series has been to achieve significant weight savings in order to increase the power-to-weight ratio. A sculptured block retains high rigidity while removing unnecessary mass. The use of composite material for the oil pan and valve cover provides further weight savings. With this innovative approach, the G Series achieves a remarkably low engine weight of just 1,900 pounds (862 kg) while retaining all the structural strength and durability expected of a Cummins Heavy-Duty engine. The G Series incorporates Cummins Xtra-High Pressure Injection (XPI) fuel system, derived from the larger and more powerful X Series engine. With multiple injection events driven by high-precision Cummins electronic controls, the XPI fuel system contributes to a very impressive peak torque for the G Series of nearly 1700 lb-ft (2300 N•m), together with a torque rise as high as 60 percent available. These attributes enable the G Series to deliver exceptionally fast response to increasing load factors from low engine rpm.
