An effort is being made at Daimler-Benz AG to utilize the special characteristics of vaporized methanol and ethanol in an alcohol-gas spark-ignited engine. Describes laboratory testing which demonstrates that waste heat recovery and very lean air/fuel mixtures improve the efficiency and economy of a spark-ignition engine running on alcohol vapors. Presents graph comparing performance and torque of the alcohol-gas and diesel engines. Finds that the fuel consumption of the methanol-fueled version approaches that of a diesel engine, with other advantages including low engine noise, good acceleration, and favorable exhaust emissions.
