ACERT Technology is an emissions management technology that was introduced in 2003 and incorporates four basic systems; air management, precision combustion, advanced electronics and effective after-treatment. These four systems work in conjunction to decrease particulate matter, oxides of nitrogen and hydrocarbon emissions while preserving the engine's reliability and durability. The Caterpillar C7 engine is said to feature an enhanced version of ACERT Technology that allows it to comply with the 2007 EPA regulations without sacrificing reliability, durability or fuel economy. Caterpillar has now sold more than 450,000 on-highway engines with ACERT Technology.
"With this certification, Caterpillar has delivered on the promises made when we introduced ACERT Technology in 2002," said Jim 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 Cat engines traditionally have provided."
