IMPROVED PERFORMANCE OF INTERNAL COMBUSTION ENGINES USING 5-30 PER CENT 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 percent 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 percent 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 percent hydrogen for a 10 percent mixture. /AUTHOR/
