Cummins Inc. has received certification for its ISX15 engine from the U.S. Environmental Protection Agency, meeting both the EPA 2013 regulations and the new greenhouse gas and fuel-efficiency rules that will take effect in 2014.
Cummins says its 2014 greenhouse gas certification is the first such engine certificate issued by the EPA.
Cummins ISX15 will deliver higher levels of fuel efficiency and reliability in 2013, according to the company. Efficiency improvements to the base engine include optimized combustion and reduced parasitic load through high-efficiency water, fuel and lube pump systems, and Cummins says the ISX15 will achieve up to 2% fuel economy improvement over today's product.
Cummins ISX15 for 2013 uses the same base engine with the XPI fuel system, VGT Turbocharger, Cummins Aftertreatment System with Diesel Particulate Filter and Selective Catalytic Reduction technology, and fully integrated electronics.
Cummins entire lineup of on-highway engines for truck, bus, RV and specialty-vehicle markets will enter production on Jan. 2, 2013. All engines are expected to be certified a full year early to the 2014 greenhouse gas and fuel-efficiency rules.
The 2013 EPA regulations require the same near-zero emission levels of oxides of nitrogen (NOx) and particulate matter as were 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.
On-board diagnostics, which were introduced on the ISX15 in 2010, are also required across the full on-highway product line in 2013. On-board diagnostics will provide enhanced service capability with standardized diagnostic trouble codes, service tool interface, in-cab warning lamp and service information availability.
Cummins Care will be available for all 2013 EPA certified engines, including natural gas engines, and is available free of charge.
