Caterpillar Inc., Peoria, Ill., has sold more than 260 engines powered with ACERT technology that will be used in the Seattle area.

The Caterpillar C9 clean diesel engines will be installed in buses made by New Flyer of America Inc., the largest manufacturer of transit buses in North America. Financial details were not disclosed.
The buses will be purchased by King County Metro, which operates a fleet of more than 1,300 vehicles and serves about 100 million riders annually in the Seattle area. Most of the buses will be equipped with diesel electric hybrid technology, which combines the power of a clean diesel engine with an electric motor. The diesel electric hybrid buses will offer a fuel efficient, low emission alternative that is particularly attractive in powering mass transit buses.
"Mass transit agencies are taking a new look at Caterpillar engines with ACERT technology, and this sale is extremely significant as we pursue more opportunities around North America," said James J. Parker, Caterpillar vice president with responsibility for the company's Power Systems Marketing Division. "We also believe Caterpillar's breakthrough ACERT technology is a particularly strong match for buses that use diesel electric hybrid technology.
This allows mass transit agencies to have another low emission and fuel efficient option to operate in demanding urban environments."
ACERT is a differentiated, breakthrough technology that reduces emissions at the point of combustion. The technology capitalizes on Caterpillar's proven leadership in engine electronics, fuel injection systems and combustion technology. All Caterpillar on-highway truck and bus engines will be equipped with ACERT technology in the fourth quarter of this year. The technology will also be used as the foundation to meet future emission regulations for the company's entire diesel engine product line, including construction and mining machines, and power generation units.
