CleanAir Logix Orders Heavy-Duty LNG Trucks for Port Operations

21 August 2008

CleanAir Logix of Oakland, California has ordered 9 Kenworth T800 heavy-duty liquefied natural gas (LNG) trucks, featuring Westport’s High Pressure Direct Injection (HPDI) technology (earlier post), for deployment at the Port of Oakland. The Port will use the trucks to haul containers to and from the site.

These LNG trucks will help support our goal, that by the year 2020, the Port of Oakland will have cut the health risk from diesel particulate matter at our seaport by 85 percent.

—Omar R. Benjamin, Executive Director at Port of Oakland

The Port of Oakland oversees the Oakland seaport, Oakland International Airport and 20 miles of waterfront. The Oakland seaport is the fifth busiest container port in the US.

Westport’s ISX G engine and liquefied natural gas (LNG) fuel system is based on the Cummins ISX diesel engine with cooled EGR. The LNG version of the engine offers the same horsepower, torque, and efficiency as the base diesel engine it is replacing. The Westport LNG fuel system comprises LNG fuel tanks, proprietary Westport fuel injectors, cryogenic fuel pumps and associated electronic components. The Westport LNG system is 2007 EPA and CARB certified to 0.8g/bhp-hr NO_x and 0.01g/bhp-hr PM.

The Westport ISX G engine is available with 400 and 450 hp (298 336 kW) and ratings and up to 1,750 lb-ft (2,373 Nm) torque for heavy-duty port, freight and vocational applications. LNG fuel tanks can be configured to suit customer range requirements. LNG heavy-duty trucks are eligible for federal tax credits in the United States and may be eligible for other state-specific emissions credits.
