COLUMBIA, S.C. — Navistar has acquired certain assets from Holley Performance Products, including intellectual property rights to some of Holley’s valve technology for diesel engine exhaust-gas recirculation systems. Navistar’s Pure Power Technologies will manufacture the advanced EGR valve at its Blythewood, S.C. 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 Eric Tech, president of Navistar Engine Group, which will use the EGR valve across its line of MaxxForce brand big bore commercial diesels.

Navistar has opted to use EGR technology over selective catalytic reduction (SCR) technology, which has been the favoured choice among other major engine manufacturers.

The advanced valve technology is designed to enable increased EGR system air flow, which helps reduce engine combustion temperatures. Low combustion temperatures are one of the keys to Navistar’s Advanced MaxxForce EGR system for meeting EPA 2010 clean-air standards which officials says lifts the burden of urea-based SCR aftertreatment off the shoulders of commercial truck operators.

“This component allows precise and efficient air management in MaxxForce engines,” said Houman Kashanipour, president of Pure Power Technologies. “As a result, Navistar customers benefit with high performance, high efficiency and low diesel emissions.”
