PEORIA, Ill. — Caterpillar Inc. has received 2004 certification by the U.S. Environmental Protection Agency for the company’s fourth on-highway truck engine equipped with the company’s ACERT technology.

Caterpillar was the first engine manufacturer to offer engines certified to EPA’s tougher 2004 standards, which require more stringent testing to demonstrate lower emissions over longer periods of engine operation.

The fourth EPA-certified Caterpillar engine is the C13 engine, popular with general freight, or line-haul truck fleets that carry goods such as home appliances, building materials, and refrigerated foods. Offered in the 335 to 430 horsepower range, the C13 is also heavily used in tanker trucks that serve the oil, petroleum and agricultural industries. The C13 is also the customer engine of choice in sales of vocational-class trucks including dump trucks, refuse haulers and cement mixers.

"With the certification of this engine, we are another step closer to full certification of truck and bus engines with ACERT technology," said Richard L. Thompson, Caterpillar group president with responsibility for the company’s engine division. "Caterpillar employees have worked very hard to bring this new technology to market. We are pleased to report that the introduction of this technology is fully on schedule and that customer acceptance of the new engines is very strong."
