2242 Title: IMPROVED FUEL COMPOSITIONS ABSTRACT OF THE DISCLOSURE Fuel compositions for internal combustion engines, and more particularly, fuel compositions for use in fuel-injected internal combustion engines are described. The fuel compositions comprise a major amount of a liquid hydrocarbon fuel and a minor, property-improving amount of a hydrocarbon-soluble dispersant prepared generally by the post-treatment of a nitrogen-containing composition with mono- and polycarboxylic acids which may be aliphatic or aromatic carboxylic acids although aromatic polycarboxylic acids are preferred. The nitrogen-containing compositions which are post-treated in accordance with the present invention are obtained by reacting an acylating agent with alkylene polyamines or alkanol amines. When fuel compositions of the present invention are utilized in internal combustion engines, and in particular, fuel- injected internal combustion engines, the amount of solid deposits of the various parts of the internal combustion engines are reduced. In particular, the use of such fuels prevents or reduces intake system deposits and injector nozzle deposits. Accordingly, methods for reducing or preventing the build-up of deposits in internal combustion engines also are described.
