Caterpillar Inc., Peoria, Ill. (, recently demonstrated it can meet stringent 2007 U.S. EPA standards for on-highway truck and bus engines. “We will provide 2007-compliant prototype engines to truckmakers later this year, and the engines will be available for customer evaluation in the mid-2005 timeframe,” says Douglas Oberhelman, Caterpillar group president.

The company says it was the first engine manufacturer to offer clean diesel engines certified to meet 2004 EPA standards. These required more stringent testing to demonstrate lower emissions over longer time periods. The engines feature Acert technology, which reduces emissions at the point of combustion. This technology, found on all Caterpillar on-highway truck and bus engines in production, will serve as the foundation to meet future emission regulations.

A 2007 emissions-compliant truck was displayed as part of the Society for Automotive Engineering (SAE) and DOE annual government/industry conference in Washington, D.C.
