Blends of up to 40% by volume methanol in a methanol-gasoline fuel blend were supplied to a single cylinder engine operating under controlled conditions. The following effects are reported as the methanol concentration increases. The lean misfire limit is extended 0.04 Ø by using a blend containing 40% methanol compared to the base fuel.It is also noted that the lean misfire limit does not vary until a blend containing greater than 20% methanol was used. Torque and thermal efficiency increase significantly. Percent by volume concentrations of carbon monoxide, carbon dioxide and oxides of nitrogen do not change, although oxides of nitrogen reported as mass per power output per hour decrease.
