Effect of alcohols as supplemental fuel for turbocharged diesel engines. [Performance of methanol, propanol, and ethanol]

Alcohols are examined as supplemental carbureted fuels for highspeed turbocharged diesels. Fumigation (dual-fueling) with alcohol significantly reduced smoke and intake manifold temperature. Efficiency and HC emissions were essentially unchanged. The range of speed and load favorable to alcohol dual-fueling are such that, should alcohols become economically competitive as fuels, as practical duel-fuel (sic) system could be applied to existing diesel engines.
