A new grant will help researchers at UW-Madison test a new class of diesel biofuels for nautical use. The Engine Research Center in UW?s College of Engineering received a $2 million grant from the U.S. Office of Naval Research to help develop a method of testing hydro-treated vegetable oil for ship and submarine engines. Rolf Reitz, director of the Engine Research Center, said the center?s six professors and a group of graduate students will work to develop a computer model that can accurately predict how certain blends of these fuels will perform in maritime engines.
