EPA certifies third Cat engine

| 6/13/2003

The U.S. Environmental Protection Agency has certified Caterpillar Inc.’s third engine equipped with ACERT technology. With this certification, Caterpillar is the first engine manufacturer to offer both medium- and heavy-duty truck and bus engines that meet EPA’s 2004 emissions standards.

The third EPA-certified Caterpillar engine with ACERT technology is the C15 engine, a clean diesel engine used by large North American truck fleets and owner-operators. Full production of the engine, offered in the 435 to 550 horsepower range, will begin in the third quarter of this year.

"This certification demonstrates that production of ACERT technology for heavy-duty trucks is on schedule," said Richard L. Thompson, Caterpillar group president with responsibility for the company's engine division.

Earlier this year, the Caterpillar C7 and C9 engines were certified for use in on-highway trucks, school buses and transit buses.

ACERT is designed to reduce emissions at the point of combustion. All Caterpillar on-highway truck and bus engines will be equipped with ACERT technology by the fourth quarter of this year.

Caterpillar manufactures and supplies truck and bus engines in the combined medium- and heavy-duty categories in North America, holding the lead position in engine shipments to vehicle manufacturers since 1999.
