Pitt Ohio to test two Mack Anthem natural gas vehicles

May 30, 2018. Pittsburgh-based carrier Pitt Ohio will test two Mack Anthem models equipped with Cummins Westport ISX12N natural gas engines during the next year as part of its ongoing commitment to reducing the environmental impact of its fleet through the use of alternative fuels.

   These two near-zero emissions trucks were the centerpiece at a recent announcement by the Pennsylvania Department of Environmental Protection of its Driving PA Forward grant and rebate programs.

   “Pitt Ohio is an industry leader in sustainability and is very forward-thinking when it comes to alternative fuel vehicles for their fleet,” said Jonathan Randall, senior vice president of sales and marketing of Mack Trucks North America. “Mack is proud to offer them these trucks to test. Their input will help us continue to improve and expand the alternative fuel options in Mack's offering.”

   The programs, launched May 10, are part of Pennsylvania's efforts to reduce vehicle and equipment emissions and improve air quality by replacing older diesel engines with new technologies. The state aims to cut nitrogen oxide (NOx) emissions by up to 27,700 tons.

   The Anthem test vehicles, provided by Mack to Pitt Ohio in cooperation with TransEdge Truck Centers in Pittsburgh, are day cabs with factory-installed fuel tanks. According to Cummins Westport, the spark-ignited ISX12N is one of the lowest certified NOx emission engines available in North America, with NOx exhaust emissions 90 percent lower than the current EPA NOx limit of 0.2 g/bhp-hr.
