IMPROVED PERFORMANCE OF INTERNAL COMBUSTION ENGINES USING 5-30% METHANOL IN GASOLINE

A number of unmodified cars have been tested over a fixed course using mixtures of methanol and gasoline. It was found that mixtures between 5 and 15% increased the fuel economy and performance, and lowered the CO emissions and exhaust temperatures. In addition, knock was eliminated on one engine and "Diesel operation" ceased with 5% or greater mixtures. The improved performance of methanol mixtures is attributed to chemical leaning plus the dissociation of methanol near 200 deg C which can absorb energy during the compression stroke of the engine and release up to 40% hydrogen for a 10% mixture.
