Navistar’s Pure Power Technologies Acquires Holley EGR Valve Technology

Advanced Air-Management Component Represents Another Key to Product Leadership Strategy

COLUMBIA, S.C., USA - Navistar, Inc. has acquired from Holley Performance Products, Inc. certain assets including intellectual property rights to some of Holley’s valve technology for diesel engine exhaust-gas recirculation systems. Pure Power Technologies LLC, a Navistar company, 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, Navistar Engine Group, which will use the EGR valve across its line of MaxxForce® brand big bore commercial diesels.

The advanced valve technology enables 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 without burdening commercial truck operators with liquid urea based selective catalytic reduction (SCR) after-treatment.

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

Navistar Engine Group designs, engineers and manufactures a full line of MaxxForce diesel engines for International® brand commercial trucks, IC™ brand school and transit buses, and Workhorse® brand custom RV chassis.

Pure Power Technologies, vertically integrates research and development, engineering and manufacturing capabilities to produce world-class diesel power systems and advanced emissions control systems. Based in Columbia, S.C., Pure Power Technologies operates an R&D center there, a manufacturing plant in nearby Blythewood, S.C., and a foundry in Waukesha, Wis.
