New MidRange Natural Gas Engine Featured at STN Expo

ISB6.7 G Natural Gas Engine a Natural Choice for Type C School Bus Market

RENO, NV, July 28, 2015 /CNW/ - Cummins Westport Inc. is introducing the 2016 ISB6.7 G, a 6.7-liter MidRange, factory-built, dedicated natural gas engine, to the Type C School bus market at the North American School Bus Show – STN Expo Conference and Trade Show July 25-28 in Reno.

The ISB6.7 G natural gas engine is based on the Cummins ISB6.7 diesel engine platform – the industry leader in the Cummins MidRange engine family and the top-selling engine in the school bus market. The ISB6.7 G is fueled by compressed natural gas (CNG), liquefied natural gas (LNG) or renewable natural gas (RNG), utilizing Cummins Westport's proprietary spark-ignited, stoichiometric combustion with cooled Exhaust Gas Recirculation (SEGR) technology. Currently in field trials, the ISB6.7 G will be in full production by mid-2016.

An important feature of the ISB6.7 G is Three-Way Catalyst (TWC) aftertreatment, which is packaged as a muffler, and is maintenance-free. No Diesel Particulate Filter (DPF) or Selective Catalytic Reduction (SCR) aftertreatment will be required.

Preliminary specifications include a range of ratings up to 260 hp and 660 lb-ft torque, and automatic transmission capability, to meet customer and original equipment manufacturer (OEM) requirements. The ISB6.7 G will be manufactured at the Cummins Rocky Mount Engine Plant in Whitakers, N.C.

"We are pleased to display the ISB6.7 G to pupil transportation professionals from across the United States and worldwide here at the STN Expo," said Rob Neitzke, President of Cummins Westport. "The ISB6.7 G is the natural choice for Type C school bus customers desiring clean, quiet and safe operations with diesel-like power and performance."

The ISB6.7 G will be certified at launch to meet the U.S. Environmental Protection Agency (EPA) and California Air Resources Board (ARB) emissions standards of 0.20 g/bhp-hr nitrogen oxides (NOx) and 0.01 g/bhp-hr particulate matter (PM), and 2017 U.S. greenhouse gas (GHG) and fuel-economy regulations.
