The company will start using the exclusive technology on all midsize and heavy duty truck engines, integrated with the next generation HEUI fuel systems, starting in the fourth quarter of 2003.

ACERT will be the primary technology for meeting government emissions regulations through 2006 and beyond, said Doug Oberhelman, vp of Caterpillar’s engine products division. ACERT is a cost-efficient emissions technology that Oberhelman says offers significant advantages over other options, including cooled exhaust gas recirculation, which several engine manufacturers are using to meet tighter nitrogen oxide (NOx) emissions limits that are expected by the government in 2002.

"This new technology is an environmentally sound solution that also offers excellent benefits to truck owners," said David Semlow, marketing manager of Caterpillar’s truck engine division. "ACERT is a customer-driven solution that is designed for the long-term."

According to John Campbell, truck engine products director in Caterpillar's performance engine products division, a major advantage of ACERT is that it will be cost effective to install.

"ACERT is an advanced fuel system and combustion technology solution that maintains today's reliability and durability standards while minimizing effects on owning and operating cost," Campbell said. "After carefully evaluating many options, we determined that ACERT provides the most value to the customer."
