Kenworth Truck Co. of Kirkland, WA added a new truck to its line of environmentally friendly vehicles. The Kenworth T800 LNG runs on liquefied natural gas (LNG). Kenworth is using LNG technology developed by Westport Innovations Inc. of Vancouver, BC. “The Kenworth T800, equipped with a Cummins ISX and Westport HPDI fuel system, offers an industry-leading solution with world-class low emissions and greenhouse gases, while delivering outstanding horsepower, torque and efficiency comparable to a diesel engine,” says Bob Christensen, Kenworth’s general manager and PACCAR vice president.
The debut of the Kenworth T800 coincides with the Ports of Los Angeles and Long Beach announcement to approve a new $1.6 billion Clean Truck Superfund. The fund will assist in replacing many of the 16,800 Class 8 trucks serving the ports with LNG-powered vehicles. The ports also introduced a ban that will remove all pre-2007 trucks by 2012.

A bold, gold, open-air coupe may not be the ticket to automotive nirvana for every consumer, but Lexus’ LF-C2 concept car certainly turned heads at the recent Los Angeles Auto Show. What’s more, it may provide a glimpse of the luxury automaker’s future.
The complexity of diesel engines means optimizing their performance requires a large amount of experimentation. Computational fluid dynamics (CFD) is a very useful and intuitive tool in this, and cold flow analysis using CFD is an ideal approach to study the flow characteristics without going into the details of chemical reactions occurring during the combustion.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
