Navistar Launches First V8 CGI Block

摘要

In order to improve the fuel economy of its diesel engines, Navistar, Warrenville, Ill., needed to find a way to make a lighter engine block, For more than 10 years the company had been researching and developing blocks using compacted graphite iron, which offers higher strength, stiffness and fatigue strength than gray iron. After successfully completing prototypes and then production V6 engines in the last few years, Navistar launched the Maxx-Force 7 in 2010, the company's first V8 series production engine produced in CGI.
