Cummins launching new global heavy-duty engine platform
G Series in-line six-cylinder diesel will be available in 10.5- and 11.8-litre displacements
COLUMBUS, Ind.—Cummins Inc. has announced the launch of a new global heavy-duty engine platform the firm said will minimize engineering requirements to make it easier for OEMs to install the powerplants in their lineups.
According to Cummins, its new G Series in-line six-cylinder diesel will be available in 10.5- and 11.8-litre displacements when it goes into production early next year.
“The G Series global design approach is a vivid demonstration of how Cummins is transforming from a multinational to a truly global company,” Cummins vice-president Steve Chapman said in a statement.
“This engine platform has been designed for diverse and global markets by utilizing the expertise and local knowledge of our engineers from around the world.”
The company said the global design approach uses an adaptive architecture, with each engine designed to meet unique performance and cost of ownership expectations for its target market and region, as well as a common, compact installation envelope.
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 allows the G Series to deliver peak torque of 1700 lb.-ft.
Cummins said the engine was also designed with an increased power-to-weight ration in mind, with the powerplant tipping the scales at a little more than 1,900 lbs. through the use of composite materials where possible.
For on-highway markets, the G Series heavy duty engine platform will be introduced as the Cummins ISG11 and ISG12.
These engines offer a power range from 290 to 512 horsepower and will be available to meet global variations in emissions requirements.
Cummins said the engines will meet Euro III and IV, and China NS4 emission requirements.
Engines for Euro V, Euro VI and U.S. Environmental Protection Agency (EPA) are also in development.
The G Series will initially be manufactured in China by the Beijing Foton Cummins Engine Company for the global market.
