New global engine range from Cummins

Cummins has announced a new global heavy-duty engine platform, which was 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 and 11.8 litre displacements to meet a broad variety of application requirements and emission standards.

Design and development of the engine was led by a team in the United States and supported by global technical and marketing resources with knowledge of local market and customer needs. Cummins said this global design approach utilises the latest advanced technologies to develop an adaptive architecture, with each engine designed to meet performance and cost of ownership expectations for its target market and region.

“The G Series global design approach is a vivid demonstration of how Cummins is transforming from a multinational to a truly global company,” said Steve Chapman, Cummins Vice President and Group Vice President China and Russia. “This engine platform has been designed for diverse and global markets by utilising the expertise and local knowledge of our engineers from around the world.”

The G Series is said to minimise engineering requirements for vehicle and equipment manufacturers with a common, compact installation envelope. A key design focus for the G Series was to achieve significant weight savings in order to increase the power-to-weight ratio.

What Cummins is calling 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 approach, the G Series is claimed to achieve an 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 ISX engine. With multiple injection events driven by high-precision Cummins electronic controls, the G Series puts out 2305 Nm (1700 ft lb) of torque.

Cummins say the G Series heavy-duty engine platform will be introduced as the Cummins ISG11 and Cummins ISG12, offering a power range from 290 to 512 hp (213 to 382 kW). At launch in 2014, engines will meet Euro III, Euro IV, and China NS4 emission requirements. Engines for Euro V, Euro VI and U.S.EPA 2010 and beyond are also in development.

“Cummins G Series will set a new benchmark as a global heavy-duty engine platform,” said Rich Freeland, Cummins Vice President and President, Engine Business. “With innovative and leading technology, the G Series will deliver superior performance to drive our customers' success.”

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