The reduction in particulate matter in the Caterpillar engines slotted for 2007 equipment is significant. "In 1988 the average EPA-compliant heavy-duty on-highway truck traveling 120,000 miles in a year emitted about 470 lb of particulate matter," explains Dough Oberhelman, Caterpillar Group president with the responsibility for Caterpillar's engine business. "The engine we demonstrated to President Bush — and the engines that our customers will use in 2007 — will emit less than 8 lb of particulate matter a year, a reduction of approximately 98 percent."
