Cummins ISX15 engine has received United States Environmental Protection Agency (EPA) certification for new greenhouse gas and fuel efficiency rules, which will take effect in 2014. Cummins ISX15 engine is the first engine to receive this certification.
The engine, which starts productions January 2—along with the entire lineup of Cummins on-highway engines for truck, bus, RV and specialty-vehicle markets—also meets the EPA’s 2013 regulations.
Efficiency improvements to Cummins ISX15 engine include optimized combustion and reduced parasitic load through high-efficiency water, fuel and lube pump systems. The ISX15 will achieve up to a 2-percent fuel economy improvement over the current product.
The ISX15 for 2013 uses the XPI fuel system, VGT Turbocharger and Cummins Aftertreatment System with diesel particulate filter (DPF) and selective catalytic reduction (SCR) technology, as well as fully integrated electronics.
On-Board Diagnostics, which were introduced on the ISX15 in 2010, are required across the full on-highway product line in 2013.
Cummins anticipates its entire lineup of on-highway engines to be certified a full year prior to the implementation of the 2014 greenhouse gas and fuel-efficiency rules. The EPA 2013 regulations require the same near-zero emission levels of oxides of nitrogen (NOx) and particulate matter (PM) required beginning in 2010.
The new greenhouse gas and fuel-efficiency regulations will be required for all heavy-duty diesel and natural gas engines beginning in January 2014.
