Westport Will Stop Taking Orders on November 15

Westport Innovations has confirmed that it’s dropping its former flagship, the Cummins ISX-based Westport 15L that uses high pressure direct injection technology to run primarily on natural gas. Westport refused to comment after Paccar told customers the LNG engine package would no longer be available (F&F, September 24), but said in its third-quarter earnings report that it would take no more orders as of mid-month.

Westport said it would continue to supply customers in Australia with the 15L.

“The last day for orders for the 15L engine with Westport HPDI with 2013 Environmental Protection Agency 2010 certification will be November 15,” Westport said.

Westport said it “plans to continue to offer an HPDI solution for Australia in concert with Westport’s fuelling partners for the foreseeable future.”

The 15-liter engine develops up to 475-horsepower but is a complex affair, requiring use of liquefied natural gas – no CNG. All Kenworth and Peterbilt trucks using the 15L have been shipped with the Westport HD fuel system comprising LNG tank, a cryogenic pump, and a high-pressure accumulator vessel for introducing the natural gas to the engine, along with a small amount of “pilot” diesel.

‘An Exciting Transition Year’

The diesel component required selective catalytic reduction, which added to the cost of 15L-powered vehicles.

The simpler, up-to-400-horsepower Cummins Westport ISX12 G allows the choice of CNG or LNG with no special pumps, accumulators, nor SCR. It has dominated the heavy duty natural gas truck order books.

Westport reported significant gains in revenue: including Cummins Westport sales of spark-ignition engines, revenue for the quarter ended September 30, was $124.0 million, compared with $76.2 million for the same period last year. Revenue for the first nine months of 2103 was $311.6 million, up from $270.8 million last year.

Westport CEO David Demers cited strong expectations for the new spark-ignition ISX12 G with Cummins Westport, and termed 2013 “an exciting transition year for us.”
