ABSTRACT:
Vehicle driveability problems associated with deposits formed in multiport fuel injectors are alleviated by delivering fuel comprising a particular amine containing various C.sub.6 to C.sub.24 alkyl, aryl, cycloaliphatic, heterocyclic, substituted alkyl or substituted aryl groups and C.sub.1 to C.sub.24 alkyl, aryl, substituted alkyl or aryl, cycloaliphatic or heterocyclic groups. Particular amines include bis(2-hydroxy ethyl) cocoamine, bis(2-hydroxy ethyl tallow amine, bis(2-hydroxy ethyl) stearylamine, dimethylcocoamine, dimethyl hydrogenated tallow amine, dimethylhexadecylamine and mixtures thereof. Fuels containing the amine are stabilized against emulsions by inclusion in the fuel of certain demulsifiers. In the preferred embodiment, the amine is in combination with an oxide derivative thereof.
