PEORIA, Ill. — Caterpillar has received certification from the US Environmental Protection Agency for its C13 and C15 engines equipped with ACERT Technology for 2007.

“These certifications demonstrate that engines with ACERT Technology for 2007 are ready to serve our customers in the North American trucking industry,” said James J. Parker, vice-president, Caterpillar Power Systems Marketing Division. “ACERT Technology has set a new industry standard for clean diesel technology, meeting the clean air goals we all support while maintaining the reliability, durability and minimal owning and operating costs that Caterpillar engines traditionally have provided.”

The new C13 is available in on-highway vocational and heavy-duty line haul configurations. The C15 provides the highest horsepower and torque rating in the industry, the company said.

CAT says ACERT Technology relies on four basic systems to lower emissions air management, precision combustion, advanced electronics and effective aftertreatment. The four systems are designed to decrease particulate matter, oxides of nitrogen and hydrocarbon emissions while preserving the engine’s reliability and durability.

Caterpillar has sold more than 450,000 on-highway engines with ACERT Technology to more than 46,000 customers since the technology was introduced in 2003.
