Effects of Alcohol Fuels on Engine Wear 800857

AN INVESTIGATION OF THE EFFECTS of methanol fuel on spark ignition engine wear and deposits is being conducted using a Ford 2.3-liter engine and a modified ASTM sequence V-D test procedure. This testing indicates that at the low temperature conditions of this procedure, methanol reduces the buildup of engine deposits but greatly increases the engine wear rate. Various experiments to identify the wear mechanisms were conducted in a CLR single-cylinder engine and are reported here.
