New Global Heavy-Duty Engine Platform

Cummins Inc. recently announced a new global Heavy-Duty engine platform that it has developed to complement its existing global product offering. The G Series platform is an in-line six cylinder engine, and will be available in 10.5 l and 11.8 l displacements to meet a broad variety of on-highway and off-highway global market requirements and emissions standards. Initial engines are designed to run on diesel fuel.

Design and development of the engine has been led by a team in the U.S., and supported by global technical and marketing resources with deep knowledge of local market and customer needs. This global design approach utilizes the latest advanced technologies to develop an adaptive architecture, with each engine designed to meet unique performance and cost-of-ownership expectations for its target market and region.

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 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 1,700 lb ft (2,305 Nm), together with a torque rise as high as 60% available. These attributes enable the G Series to deliver exceptionally fast response to increasing load factors from low engine rpm.

For on-highway markets, the G Series Heavy-Duty engine platform will be introduced as the Cummins ISG11 and Cummins ISG12. These engines offer a power range from 290 hp to 512 hp.

One engine from the new G Series platform was unveiled at bauma, held in Munich, Germany, in April 2013, under the name QSM12, and will now be renamed QSG12 as part of this family of engines.

The G Series will initially be manufactured at the Beijing Foton Cummins Engine Co., serving customers on a global basis. Production will start during the first half of 2014.
