Navistar's MaxxForce 13 liter engine receives EPA certification

Niels Tholen - 18 April 2013

Navistar reported on April 17 that it has received U.S. Environmental Protection Agency (EPA) certification for its MaxxForce 13 liter engine.

The heavy-duty big bore engine uses Selective Catalytic Reduction (SCR) technology and production is now ready to begin, with first customer delivery scheduled for later this month.

The SCR technology is provided by Cummins and certified to emit no more than 0.2 g/bhp-hr. With the accreditation of the new engine, Navistar reports that it now offers a complete line-up of SCR-based products for the heavy-duty on-highway truck market.

Jack Allen, Executive Vice President and Chief Operating Officer at Navistar, said: "EPA certification of our proprietary 13 liter engine with SCR completes our transition to SCR-based technology for our heavy-duty engines. We've reached another milestone in our emissions strategy transition and are on track to deliver our first ProStar units with our SCR-based 13-liter engines at the end of April."
