Cummins Inc. says the U.S. Environmental Protection Agency (EPA) has certified that the company’s complete lineup of on-highway diesel and natural gas engines complies with the Phase II greenhouse-gas (GHG) and fuel-efficiency standards, which take effect in January 2017. According to Cummins, the certifications cover its commercial vehicle engines ranging from 5.0 liters to 15 liters.
“Cummins is committed to providing customer-focused innovation as soon as it is ready,” says Amy Boerger, Cummins’ vice president of sales and support. “For example, efficiency improvements implemented in the 2016 ISX15 400 hp-to-475 hp ratings will provide customers with fuel economy gains over the 2013 ISX15, ranging from 2.5 percent on the base engine up to 7.5 percent with a SmartAdvantage Powertrain with ADEPT (SmartCoast) features.”
Throughout 2014 and 2015, Cummins implemented efficiency enhancements that enable its engines to meet 2016 and 2017 requirements. The company says it met on-board diagnostics requirements with enhanced monitors, ensuring that exhaust tailpipe emissions stay within the EPA limits. Furthermore, a particulate matter sensor has been implemented, and electronic controls have been enhanced to interact with the diesel exhaust fluid (DEF) quality sensor implemented by original equipment manufacturers on DEF tanks.
Cummins says it plans to incorporate further product enhancements to improve performance, reliability and efficiency throughout 2016.
