– 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.
