Liquid fuel for internal combustion engine

Abstract

A liquid fuel for internal combustion engine, comprising 2 to 85 wt % of an alcohol component of aliphatic monohydric alcohol having 2 to 6 carbon atoms per molecule per se or a mixture thereof and 15 to 98 wt. % of a hydrocarbon component. The liquid fuel for internal combustion engine contains an aluminum corrosion inhibitor in an amount capable of inhibiting the aluminum corrosion at predetermined given temperature. The aluminum corrosion inhibitor comprises at least one member selected from among methanol, glycol hydrocarbons, ketone hydrocarbons, ester hydrocarbons and aldehyde hydrocarbons.
