Cummins Westport was nominated by an independent panel made up of DOE,

decisions that contribute to the reduction of petroleum consumption.

"It is a great honor to be recognized by the US Department of Energy for
Cummins Westport's efforts to provide alternative fuel engines to
improve our environment," said Cummins Westport President Guan Saw. "We
are very proud of our products. This award recognizes our commitment to
helping solve emissions challenges posed by transportation, while at the
same time providing the performance, reliability, and durability that
customers demand."

engine development program as evidence of the company's committment to
improving natural gas engines. Important design parameters for the
engine will include improved fuel efficiency, reliability, lower total
