SINGLE CYLINDER SPARK IGNITION ENGINE STUDY OF THE OCTANE EMISSIONSAND FUEL ECONOMY CHARACTERISTICS OF METHANOL-GASOLINE BLENDS

Test program was carried out on a single cylinder, fuel research engine (CFR) to determine the octane, emissions, and fuel economy characteristics of methanol-gasoline blends. The first phase of the work was an evaluation of the octane characteristics of methanol blended with unleaded gasoline. The second phase of the test program was an evaluation of the emissions and fuel economy of a 10% by volume blend of methanol with two base fuels in the single cylinder engine. Genral conclusions were that a blend of 10% methanol and gasoline demonstrated no significant change in the emissions or energy efficiency over the gasoline fueled engine when operated at equivalent conditions. Under some operating conditions, the addition of methanol could increase the octane rating of the base fuel. /GMRL/
