Caterpillar Inc. has received 2004 certification by the U.S. Environmental Protection Agency (EPA) for the company’s fourth on-highway truck and bus 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 with ACERT technology 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 hp (249 to 320 kW) range, the C13 also is heavily used in tanker trucks that serve the oil, petroleum and agricultural industries. The C13 also is the customer engine of choice in sales of vocational-class trucks including dump trucks, refuse haulers and cement mixers.

“With the certification of the 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.”

Earlier this year, the Caterpillar C7 and C9 engines were certified for use in on-highway trucks, school buses and transit buses. With certification of the company’s C15 engine in March, Caterpillar became the first engine manufacturer to earn EPA 2004 certification of a heavy-duty on-highway truck engine.

ACERT is a differentiated technology that reduces emissions at the point of combustion. All Caterpillar on-highway truck and bus engines will be equipped with ACERT technology in the fourth quarter of this year. This technology also will 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.

Caterpillar is a manufacturer and supplier of 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. Three years in a row, Caterpillar engines have received the highest customer satisfaction rankings released by J.D. Power and Associates.
