Work on several aspects of using pure methanol as an alternate fuel are reported. A stock (OEM) Pinto engine mounted on a dynamometer was used to compare methanol with Indolene in terms of power, efficiency, and emissions for a variety of speeds and loads. Although the engine was designed for use with gasoline, it was found that methanol was generally superior in power, thermal efficiency and reduced emissions with the exception of aldehydes. Three different fuel metering systems were tested for a variety of speeds and loads using the dynamometer mounted engine. They were all found to provide superior steady state performance on methanol when compared with the OEM carburetor system with enlarged fuel jets for methanol. Mileage and emissions from a Pinto vehicle equipped with the various fuel metering systems were computer predicted for the Federal emissions test procedure using laboratory engine measurements. A computer was used to simulate the test engine's thermokinetic combustion events. The computer model predicts power, fuel economy and emissions with air-fuel ratio, compression ratio, spark advance and speed as parameters. A small (60 hp) gas turbine was converted to run on methanol. The conversion was easily accomplished, but atomization of the fuel was found to be important in obtaining a reduction in CO and NO sub x for methanol in comparison with jet engine fuel. Environmental factors of marine and aquatic methanol spills and photochemical smog are under study. Preliminary experimentation relative to marine spills indicates that methanol is naturally present in that environment. It appears at this early stage of investigation that damage to the ecosystem from a major coastal spill may be localized and of short duration. (ERA citation 03:018814)
