Total Transportation Services, Rancho Dominguez, Calif., is operating eight Kenworth T800 LNG trucks, the first alternative fuel vehicles to operate in full-time drayage service at the Ports of Los Angeles and Long Beach under the Clean Trucks Program.

"We all have a responsibility to protect our environment," said Vic La Rosa, president of TTSI. "I'm delighted that TTSI took a lead role to put our new Kenworth T800 LNG (Liquefied Natural Gas) trucks into service to help reduce emissions and provide cleaner air at the Ports of Los Angeles and Long Beach and in the region."

The eight Kenworth T800s are equipped with the LNG fuel system developed by Westport Innovations of Vancouver, B.C., and installed on the Cummins ISX 15-liter engine. The Kenworth trucks have Westport's High Pressure Direct Injection (HPDI) technology and use 5% diesel and 95% natural gas to power the drivetrain. Running on clean, low-carbon LNG fuel, TTSI will realize greenhouse gas emission reductions of approximately 20% and nitrogen oxide emissions reductions of over 75% compared to the diesel vehicles being replaced, according to Westport Innovations.

TTSI will take delivery of 30 more later this summer, and plans to eventually replace half of its 300-truck fleet with the alternative fuel trucks, said La Rosa.

TTSI hauls a variety of commodities, from electronics to food, apparel, and appliances, for major merchandisers, manufacturers and other shippers.

Kenworth plans to go into full production of the T800 LNG trucks in 2009.
