EPA certifies CAT's ACERT technology

| Tuesday, January 21, 2003

The U.S. Environmental Protection Agency has certified Caterpillar Inc.’s emission-reduction approach, known as Advanced Combustion Emission Reduction Technology (ACERT).

The development positions Caterpillar to meet future EPA emissions regulations for both on- and off-highway engines, the company said.

Richard L. Thompson, Caterpillar group president, said, "ACERT will set a new industry standard for clean diesel engine technology in both on-highway trucks and buses, as well as off-road Caterpillar construction and mining machines."

The first EPA-certified Caterpillar engine with ACERT technology is the C9 engine, which is popular with customers who operate emergency and recreational vehicles, mass transit buses and vocational class trucks, such as refuse haulers and dump trucks.

Full production of the C9 with ACERT technology will begin in the first quarter of this year.

All Caterpillar on-highway truck and bus engines will be equipped with ACERT technology by the fourth quarter of 2003, the company said. The technology also will be used to meet future emissions regulations for Caterpillar’s entire diesel engine product line, including construction and mining machines and power-generation units.
