GREENSBORO, NC - Mack Trucks, Inc. diesel engines have been certified by the U.S. Environmental Protection Agency and the California Air Resources Board to meet the near-zero emissions standards which take effect in January 2010. The Mack MP7 and MP8 engines are now officially recognized to meet the strictest diesel emissions standards in the world. The EPA certification was issued today, and the CARB certification on November 10th.
The Mack engines have been fully certified to meet EPA's stringent standards without the use of emissions credits. Mack is the first truck manufacturer to have its heavy-duty diesel engines certified for 2010 by both EPA and CARB.
"Achieving certification involved many dedicated employees working for many years," said Kevin Flaherty, Mack senior vice president. "It's critical that our MP engines continue to deliver the power, performance, durability and reliability for which they are known. Our customers now not only have the cleanest engines in the world, they also have the performance they expect from Mack."
"The new Mack engines are so clean that in some areas, the exhaust leaving our trucks will be cleaner than the air going in," Flaherty said. "Our EPA'10 engines also have significantly improved fuel economy. Using less fuel shrinks the trucks' carbon footprint, reduces operating costs for customers and cuts the need for imported oil."
This major step forward is driven by Mack's use of selective catalytic reduction (SCR) to bring nitrogen oxides (NOx) emissions down to EPA'10 levels. Mack tested SCR in North America customer fleets for more than two years, accumulating 5 million miles of field testing. The technology has billions of miles of real-world experience in other markets. The Mack SCR technology also essentially eliminates active regenerations of the diesel particulate filter (DPF) to save even more fuel and further reduce operating costs.
SCR enabled Mack to use the proven MP series without major modifications to the engines or cooling systems. SCR permitted Mack engineers to retune the MP engines for additional power, lower heat rejection and reduced fuel consumption.
