Engines could become lighter and more efficient because of a research project that combines the talents and resources of the Chrysler Group, Nemak S.A. of Mexico and Oak Ridge National Laboratory. The goal of the four-year $5.5 million cooperative research and development agreement is to develop an advanced cast aluminum alloy for next-generation higher efficiency engines. In addition to being lighter, the new alloy for cylinder heads would be stronger and capable of sustaining the higher temperatures and pressures of engines with improved efficiency, according to ORNL’s Amit Shyam, who leads the project.
