DALLAS — Cummins Westport Inc., the joint venture between Cummins Inc. and Westport innovations that makes natural-gas engines, unveiled a new 6.7-liter nat-gas engine that will be in full production next year.

The ISB6.7 G engine — which is based on Cummins’ ISB6.7 diesel engine platform — will be marketed toward school and shuttle bus, medium-duty truck and vocational applications.

It is currently in field trials, with full production expected in mid-2016, Cummins Westport President Rob Neitzke said in unveiling the engine on the ACT Expo show floor as the expo floor opened May 5.

The engine "will offer customers low emissions with diesel-like performance, reliability and durability," with the ability to use either compressed or liquefied natural gas, Neitzke said.



The ISB6.7 G will be manufactured in Cummins’ medium-duty engine plant in Rocky Mount, North Carolina.
