Navistar has acquired intellectual property rights to exhaust recirculation gas valve technology for diesel engine exhaust gas recirculation systems from Holley Performance Products. Its Pure Power Technologies unit will manufacture the EGR valve at its Blythewood, South Carolina, plant. Terms of the deal were not disclosed.

"This aligns with our business strategy of controlling our destiny by gaining control of critical component technologies which drive differentiation in today's modern diesel engines," said Navistar engine group president Eric Tech. His division will use the valve in its line of MaxxForce big bore commercial diesels.

The acquired valve technology enables increased EGR system air flow, which helps reduce engine combustion temperatures. Low combustion temperatures are one of the keys to meeting EPA 2010 clean air standards without burdening commercial truck operators with liquid urea based selective catalytic reduction (SCR) after-treatment.
