Caterpillar Inc. has received certification by the U.S. Environmental Protection Agency for the company’s third engine equipped with ACERT technology.

With this certification, Caterpillar says it is the first engine manufacturer to offer 2004 model year clean diesel engines that are fully EPA-compliant in both the heavy- and medium-duty truck categories.
The third EPA-certified Caterpillar engine with ACERT technology is the C15 engine, an award-winning clean diesel engine used by large North American truck fleets and owner operators. In addition, the engine is popular with operators of fire trucks and emergency vehicles.
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 and the technology is ready to serve our customers in the North American trucking industry," 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. Caterpillar’s full line of on-highway engines with ACERT technology will be in production during the fourth quarter of this year.
ACERT is a differentiated, breakthrough technology that reduces emissions at the point of combustion. The technology capitalizes on engine electronics, fuel injection systems and combustion technology.
