Several types of heat engines are considered as candidates for a methanol engine. Of those considered, the stratified-charge engine appears to be the most attractive. A stratified-charge engine optimized for methanol fuel is projected to result in an energy economy advantage of 44 to 71 percent (measured in miles per Btu) in comparison to an Otto engine operating on gasoline. This advantage arises from (1) the high octane rating of the fuel, which allows a high compression ratio to be used; (2) methanol's fuel-lean combustion characteristics, which allow efficient lean operation; and (3) the low flame temperature, which allows effective control of nitrogen oxide emissions. The design and optimization of a methanol engine are examined in terms of an experimental and calculational program. The relevant properties of methanol that should prove desirable in future engines are noted, and the socioeconomic impact of methanol-fueled transportation is discussed. (ERA citation 02:003446)
