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.

Eric Tech, president of Navistar Engine Group, said: "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."

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

Pure Power Technologies integrates R&D, engineering and manufacturing capabilities to produce diesel power systems and advanced emissions control systems.

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.
