WASHINGTON, D.C. – Caterpillar Inc. committed to the Environmental Protection Agency (EPA) that it will be ready to provide customers with on-highway truck engines that will meet the EPA’s stringent 2007 emissions standards. As part of an industry-wide, clean-diesel event held near EPA headquarters in Washington, Caterpillar demonstrated its on-highway engine for the EPA. In May 2005, Caterpillar also demonstrated a 2007 compliant truck engine for President George Bush at an event in Virginia. The President examined a white handkerchief that had been held over the exhaust stack of a truck as the engine was revved. Following the demonstration, the handkerchief was still white. As part of a comprehensive testing program to make sure customers are familiar with the technology used to meet emissions regulations, Caterpillar customers have already logged more than 2 million miles on 2007-compliant engines. Caterpillar is building on its ACERT Technology to meet the 2007 regulations, adding clean gas induction and a diesel particulate filter to make sure the engines provided to customers will meet the 2007 EPA standards. The Caterpillar truck engine demonstrated for the EPA uses ultra low sulfur diesel fuel, a key component for all on-highway truck engine manufacturers to meet the 2007 emissions standards. Caterpillar has invested more than $1 billion in clean-diesel technology in recent years, and customers using Caterpillar engines featuring ACERT Technology have experienced improved fuel economy without a loss of reliability or durability.
