The Effects of Alcohol Fuels and Fully Formulated Lubricants on Engine Wear 811199
An investigation of the effects of alcohol fuels and lubricant formulations on spark ignition engine wear and deposition was jointly sponsored by the U.S. Department of Energy and the U.S. Army Mobility Equipment Research and Development Command. Tests were conducted using neat methanol, anhydrous ethanol, and alcohol blends as fuel in a 2.3-liter engine using a modified ASTM Sequence V-D test procedure. This dynamometer testing indicates that alcohol fuels reduce the buildup of engine deposits. Also, it was found that neat methanol greatly increases engine wear rates while anhydrous ethanol and alcohol-gasoline blends do not increase wear rates over that of unleaded gasoline. A 20-hour steady-state test was developed which shows that engine wear is inversely related to engine oil temperature when using methanol as fuel. The study shows that one lubricant appears to best control methanol-related engine wear, but still not to acceptable levels.
