Improved performance of internal combustion engines using 5--30% methanol in gasoline

Book ·
OSTI ID:7128773

Vehicle performance, fuel economy, and exhaust emissions were measured during road tests of various unmodified automobiles (model years 1968 to 1974) using mixtures of methanol and gasoline. Carbon monoxide emissions were reduced from between 20 to 70 percent with mixtures containing from 5 to 15 percent methanol. Fuel economy and performance were increased. The improved performance with methanol addition was attributed to chemical leaning plus the dissociation of methanol near 200/sup 0/C, leading to the absorption of energy during the compression stroke of the engine and the release of up to 40 percent hydrogen for a 10 percent mixture.
