American engine supplier Cummins has developed an engine series specifically destined for the Chinese and similar non-US markets. Called the G-Series, the new engines, which come in displacements of eleven and twelve litres, will be mounted firstly in Chinese Foton Auman GTL trucks (pic left).
The new engines have a slimmer design and make do with less components, Cummins says. The engines will be available in a 290 to 512 hp power range. Up to the choice of the customer, the engines comply with Euro 3,4, 5 or even 6. The first engines also meet the Chinese NS4 requirements.
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 peak torque for the G Series of 1700 lb-ft (2305 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. Some years ago, Cummins developed XPI injection together with Scania.
Cummins is looking for other exportmarkets for these engines as well. The company also develops a version that meets EPA requirements, for the North American market.
