Broader Cummins Westport ISB6.7 G Availability Touted
As Volvo Gets Set to Make HPDI Power Available in 2017

The Cummins Westport joint venture and partner Westport Fuel Systems are making significant progress with both natural gas engines. Cummins Westport this month announced full availability of its 6.7-liter dedicated natural gas ISB6.7 G midrange engine, while reports point to commercialization of parent Westport’s HPDI/high pressure direct injection technology for heavy natural gas-diesel dual fuel vehicles by Volvo.

Westport's HPDI 2.0 injectors are to be available to fit the diesel-cycle engines produced by multiple manufacturers.

The ISB6.7 G, available since this past May from Thomas Built Buses for school transportation, “is now fully available as a production engine for shuttle bus, medium duty truck, and vocational applications in North America,” Cummins Westport says. The new range of applications, the company says, “more than doubles its addressable market.”

“An engine of this size is a natural addition to CWI’s portfolio of natural gas engines,” Cummins Westport president Rob Neitzke says in a release.

‘The Most Cost-Effective Overall Solution’

“Many customers using school and shuttle buses, medium duty trucks, or vocational vehicles operate within a local area where the return to base nature of their operation allows them to use fleet-owned or growing publicly available natural gas fueling infrastructure.

Cummins Westport president Rob Neitzke unveiled the new engine at ACT Expo 2015 in Dallas on Tuesday evening.

“The ISB6.7 G,” Neitzke said, “offers the midrange customer an ability to take advantage of the most cost-effective overall solution with the benefit of a low emission natural gas engine that has proven performance, reliability, and durability.”

Built by Cummins

The ISB6.7 G is manufactured by joint venture partner Cummins and offered in three ratings up to 240-horsepower and 560 foot-pounds of torque.

Separately, NGV Global, citing a report in Sweden, spread the word this month that Volvo would offer HPDI power, with LNG/liquefied natural gas as fuel (along with “pilot” diesel for ignition) as an option by the end of 2017.

A Boost for Westport?

The Volvo business is expected be a shot in the arm for Westport, Craig-Hallum institutional research analysts Eric Stine and Aaron Spychalla said in a research note released this past Friday.

“To our knowledge,” they write, citing the NGV Global report, “this is the first time that Volvo (or any OEM) has publically provided a planned launch date for HPDI following many years of development.”

Westport Too Sees 2017 HPDI Commercialization

“With the shift to alternative fuels driven by straightforward economics and the competitive advantage gained, we believe that Westport Fuel Systems is at very early stages of a meaningful growth ramp.”

Westport reported key agreements with Volvo for HPDI commercialization last year (F&F, October 21, 2015), and told F&F late this past summer that its improved HPDI 2.0 technology would be commercialized internationally next year (F&F, August 30).
