(EnergyAsia, March 19, Wednesay) — Westport Innovations Inc, leading developer of gaseous-fuelled power technologies, said it has received certification from the Australian Department of Infrastructure, Transport, Regional Development for its high pressure direct injection (HPDI) liquefied natural gas (LNG)  fuel system adapted to the 2008 Cummins ISX heavy-duty engine to the 2008 Australian Design Rules (ADR 80/02 and ADR 30/01).

Four Kenworth trucks equipped with Westport’s LNG fuel system have achieved over 100,000 kilometers in commercial service through the end of 2007 in a demonstration project funded in part by the government’s alternative fuel conversion programme.

Fleets participating in the project, which will run through March 31, are Murray Goulburn Cooperative, Sands Fridge Lines, and Mitchell Corp.

Westport vice president of market development Bruce Hodgins said:

“This certification is an important step to allow sales of new LNG vehicles in the Australian market with Westport’s direct injection natural gas technology. We are now working towards commercial launch and customer deliveries of Westport-equipped heavy-duty trucks.”

Westport has also established a local entity, Westport Innovations (Australia) Pty Ltd, a wholly-owned subsidiary of Westport Innovations.

The testing of the Australian HPDI engine at Westport’s facilities and the Department of Infrastructure, Transport, Regional Development and Local Government registered facility, validated greenhouse gas tailpipe reductions of 24% to 28% on the composite steady-state test (ESC) and transient (FTP) cycles.

Regulated emissions were well within the ADR 80/02 limits, and particulate matter (PM) was reduced 54% and 40% relative to the 2008 ISX diesel on the FTP and ESC cycles, respectively.

Australian customers can now order the Westport direct injection LNG system for selected truck configurations, with deliveries anticipated to begin in the fourth quarter of this year.
