In machines, drivetrains are the components that transfer power from the inside of the machine to the outside world. During the years 2008-2015, the Environmental Protection Agency (EPA) will be phasing in so-called "Tier 4" emissions standards for off-highway machines, such as those used in construction and agriculture. During this time, these machines must further reduce their emissions of particulate matter and nitrogen oxides from present levels. A team led by Caterpillar and including The Lubrizol Corporation (Wickliffe, Ohio) in collaboration with Argonne National Laboratory (Argonne, Ill.) and Northwestern University (Evanston, Ill.) proposes developing technologies for a new generation of drive train systems in order to help machines comply with Tier 4 emissions. Goals include reducing the sizes of drivetrain components while maintaining service life, and creating a new lubricant that will be used universally in different parts of the drivetrain. Toward these ends, they propose developing graded nano—crystalline surface material technology to improve component durability, and new surface texturing technology to improve lubrication and reduce friction. ATP funding for this challenging project enables a coherent, focused multi-disciplinary team from many organizations, which individually could not provide the resources necessary for success. Caterpillar and their collaborators estimate that improved drivetrain systems can save $1.062 billion a year in fuel, reduce the trade deficit by $566 million per year, reduce 3.6 million metric tons of greenhouse gases a year, and create over 10,000 jobs.
