    Marine engine research informs next-generation lubricants

    Oak Ridge National Laboratory (ORNL) partnered with ExxonMobil to study next generation marine lubricants using a one-of-a-kind experimental engine. Located at the Department of Energy’s National Transportation Research Center at ORNL’s Hardin Valley Campus, the Enterprise is a flexible-fuel, single-cylinder marine diesel engine custom-built to one-tenth scale by Dumarey. Standing 12 feet tall, weighing over 16,000 pounds, and running at 625 revolutions per minute, the test-engine matches full-scale piston speeds to evaluate lubricants in real-world conditions.
