Westport Innovations Inc. and PACCAR Australia Pty Ltd. will develop and commercialize liquefied natural gas (LNG) Kenworth trucks for the Australian market. The LNG trucks will feature the Westport high pressure direct injection (HPDI) LNG engine and fuel system. (Earlier post.)
Australia’s Kenworth Trucks, a division of PACCAR, plans to begin factory-installed production in mid-2009 beginning with the T908, K108 and T408SAR truck chassis and roll out across additional models into the future.
Westport’s ISX G engine and liquefied natural gas (LNG) fuel system for heavy-duty trucks allows trucking fleets to move to lower-cost, domestically available natural gas and/or biogas while offering greenhouse gas reductions compared with similar diesel engines.
Based on the industry-leading Cummins ISX diesel engine with cooled EGR, Westport’s direct-injection LNG version of the engine offers the same horsepower, torque, and efficiency as the base diesel engine it is replacing, with ratings in the Australian market of up to 1,850 lb-ft (2,508 Nm) torque and 580 peak horsepower (433 kW).
The Westport LNG fuel system comprises LNG fuel tanks, proprietary Westport fuel injectors, cryogenic fuel pumps and associated electronic components.
The Australian Government has been supportive of the introduction of Westport’s LNG fuel system into the Australian market with demonstration funding.
