US: Cummins gains EPA certification for ISX15 engine

Cummins has received certification for its ISX15 engine from 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 such engine certificate issued by the EPA.

Cummins claims the ISX15 is the top-selling engine in the heavy-duty truck market and that it will deliver higher levels of fuel efficiency and reliability in 2013. Efficiency improvements to the base engine include optimised combustion and reduced parasitic load through high-efficiency water, fuel and lube pump systems, helping the ISX15 to achieve up to 2% fuel economy improvement over today’s product.

The ISX15 for 2013 uses the same base engine with the XPI fuel system, VGT turbocharger, Cummins aftertreatment system with diesel particulate filter (DPF) and selective catalytic reduction (SCR) technology, and fully integrated electronics.

Jeff Jones, Cummins Vice President – Sales and Market Communications, commented: “Cummins 2013 truck engines will deliver better fuel economy with no major hardware changes. 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’ line-up of on-highway engines for truck, bus, RV and specialty-vehicle markets will enter production on 2 January 2013. All engines are expected to be certified a full year early to the 2014 greenhouse gas and fuel-efficiency rules.

The EPA 2013 regulations require the same near-zero emission levels of NOx and Particulate Matter (PM) 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.

Jim Hebe, Navistar’s North American sales Vice President, recently confirmed that Cummins will supply the ISX15 engine to Navistar, which has decided to use it instead of its own MaxxForce 15, which will cease production in Q1 2013.
