Cummins has announced it has received certification for its lineup of on-highway diesel and natural gas engines from the Environmental Protection Agency.
The certification means Cummins meets both the current EPA regulations and the second step in greenhouse gas and fuel-efficiency standards which take effect in January 2017.
“Cummins is committed to providing customer-focused innovation as soon as it is ready,” said Amy Boerger, 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 says it implemented efficiency enhancements that enable its engines to meet EPA 2016 and GHG 2017 requirements. On-board diagnostics requirements are met with enhanced monitors, ensuring that exhaust tailpipe emissions stay within the EPA limits.
A particulate matter sensor has been implemented, and electronic controls have been enhanced to interact with the diesel exhaust fluid quality sensor implemented by OEMs on DEF tanks.
