INBRIEF Cummins unveils G Series global platform, new V8 engine C ummins announced a new global heavy-duty engine platform to complement its existing global product offering. The G Series platform is an inline 6-cylinder engine and will be available in 10.5- and 11.8-liter displacements to meet a broad For on-highway markets, the G variety of on- and off-highway global marSeries will be introduced as the ket requirements and emissions standards. Cummins ISG11 and ISG12 with a power range from 290 to 512 hp. Design and development of the 1,900pound diesel engine was led by a team in the United States and supported by global technical and marketing resources with knowledge of local market needs. The G Series incorporates Cummins' Xtra-High Pressure Injection fuel system derived from the larger and more powerful X Series engine. With multiple injection events driven by high-precision electronic controls, the XPI fuel system contributes to a peak torque of 1,700 lb.-ft., with an available torque rise as high as 60 percent. For on-highway markets, the G Series will be introduced as the Cummins ISG11 and ISG12 with a power range from 290 to 512 hp. Engines will be available to meet global variations in emissions requirements for long-haul, regional-haul and vocational service. The G Series initially will be manufactured at the Beijing Foton Cummins Engine Co. Production will start during the first half of 2014. New V8 engine Cummins also announced the ISV5.0, a new 5-liter V8 diesel engine designed to power pickup-and-delivery vehicles, other light- and medium-duty trucks, school buses and motorhomes. The ISV5.0, designed to fit where a comparable V8 or V10 gasoline engine was installed, brings together a compacted graphite iron (CGI) cylinder block, forged steel crankshaft and high-strength aluminum alloy heads that, along with dual overhead camshafts, contribute to minimize noise, vibration and harshness. High injection pressures from the Bosch High Pressure Common Rail fuel system and piezo fuel injectors help provide precise fuel control for optimized in-cylinder combustion. The HPCR fuel system, along with Cummins' VGT Variable Geometry Turbocharger, contributes to a peak torque of 560 lb.-ft. and quicker throttle response. Ratings from 200 to 275 horsepower are available. A two-stage fuel filter features NanoNet media from Cummins Filtration to keep the HPCR fuel system protected against fuel contamination. Cummins' VGT Turbocharger, cooled exhaust gas recirculation, diesel particulate filter and selective catalytic reduction result in near-zero oxides of nitrogen and particulate matter emissions. Cummins ISV5.0 will be certified to the near-zero NOx and PM emissions levels required by the U.S. Environmental Protection Agency. At launch, it also will meet greenhouse gas requirements through 2016, as well as 2015 California Air Resources Board standards. The ISV5.0 will be manufactured at the company's engine plant in Columbus, Ind. Production will start during the fourth quarter of 2014. – Jack Roberts and Jeff Crissey 28 COMMERCIAL CARRIER JOURNAL | NOVEMBER 2013
