COLUMBUS, Ind. — Cummins’ ISX15 engine has been certified by the US Environmental Protection Agency (EPA), meeting both the EPA 2013 regulations and the new greenhouse gas and fuel-efficiency rules that will take effect in 2014. Cummins 2014 greenhouse gas certification is the first engine certificate issued by the EPA, the company said.
Cummins says efficiency improvements to its base engine include optimized combustion and reduced parasitic load through high-efficiency water, fuel and lube pump systems. Officials say the ISX15 will achieve up to 2% fuel economy improvement over today’s product. The Cummins ISX15 for 2013 will use 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 2013 truck engines will deliver better fuel economy with no major hardware changes,” said Jeff Jones, Cummins’ vice-president of sales and market communications. “This results in improved reliability due to stable architecture.
“The certification of the ISX15 demonstrates Cummins commitment to deliver products that exceed both environmental and customer requirements. We are confident that we’ll receive certification for our other on-highway engines well before the end of the year.”
Cummins entire lineup of on-highway engines for truck, bus, RV and specialty-vehicle markets will enter production on Jan. 2. Company officials say they expect all engines to be certified a full year early to the 2014 greenhouse gas and fuel-efficiency rules.
