New Global Engine Platform From Cummins

Posted on September 16, 2013

Cummins Inc. has announced a new a new global heavy-duty engine platform that the company said will complement its existing product offering. The G Series platform is an in-line six cylinder engine that will be available in 10.5 and 11.8 L displacements to meet a broad variety of on-highway and off-highway global market requirements and emissions standards.

For on-highway markets, the G Series Heavy-Duty engine platform will be introduced as the Cummins ISG11 and Cummins ISG12, with ratings from 290 to 512 hp (216 to 382 kW). At launch in 2014, engines will meet Euro 3I, Euro 4 and China NS4 emissions requirements, Cummins said. Engines capable of meeting Euro 5, Euro 6 and U.S. Environmental Protection Agency (EPA) emissions levels are also in development, the company said. The ISG11 and ISG12 are targeted toward long-haul, regional-haul and vocational service, as well as buses, motor coaches, fire trucks and recreational vehicles.

The QSM12, which was unveiled at bauma 2013 in April, is part of the G Series platform and has been renamed the QSG12 to reflect its family heritage. The engine, which meets U.S. EPA Tier 4 final and European Union (EU) Stage 4 emissions regulations, is available in 335 to 512 hp (250 to382 kW) ratings.

Design and development of the G Series engines has been led by a team in the United States, supported by global technical and marketing resources, the company said. "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 utilizing the expertise and local knowledge of our engineers from around the world."

The initial engines are designed to run on diesel fuel, Cummins said, apparently leaving the door open for natural gas or other alternative fuel versions later.

The G Series will initially be manufactured at the Beijing Foton Cummins Engine Co., with production beginning in the first half of 2014.
