The U.S. Environmental Protection Agency (EPA) has certified Navistar Inc.’s 13-liter engines with selective catalytic reduction (SCR) emissions technology. The engine is certified by EPA at or below the required 0.20 g/bhp-hr NOx.
"EPA certification of our proprietary 13-liter engine with SCR completes our transition to SCR-based technology for our heavy-duty engines," said Jack Allen, Navistar executive vice president and chief operating officer. "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."
Navistar introduced its first SCR-based commercial trucks for the U.S. and Canadian markets in December 2012 with the launch of the International ProStar with the Cummins ISX 15-liter engine. With the introduction of the ProStar equipped with the company's proprietary 13-liter with SCR, International now offers a complete line-up of clean engine SCR-based product offerings for the Class 8 on-highway market.
