Mack Trucks this week demonstrated the fuel efficiency and near-zero emissions of its diesel engines and emissions control systems at the Clean Diesel Power event hosted by the Diesel Technology Forum in downtown Washington, D.C. Mack displayed a Pinnacle tractor equipped with selective catalytic reduction (SCR) emissions control system to comply with the U.S. Environmental Protection Agency’s 2010 emissions standards for nitrogen oxides and particulate matter.

The Pinnacle model was equipped for long-haul highway service with a 60-inch midrise sleeper and a 13-liter Mack MP8 engine. Mack says the MP series engines and the Mack SCR technology combine to deliver better fuel economy and lower operating costs, while meeting the near-zero emissions required by EPA. Mack officials at the event pointed out that better fuel economy means lower emissions of greenhouse gases, a smaller carbon footprint and less dependence on imported oil, all of which benefit society.

Mack says its SCR technology also essentially eliminates active regenerations of the diesel particulate filter, saving even more fuel and further reducing operating costs. The company says it has been testing SCR in North America customer fleets for more than two years, and that the technology has billions of miles of real-world experience in other markets. Mack says it already is building customer production-level trucks in its Macungie Assembly Operations outside Allentown, Pa.
