Abstract: 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.

Abstract: A fuel composition containing a fuel additive which comprises a metal compound has been developed which fuel composition is stable upon storage. It has been discovered that a fuel additive comprising a metal compound and an oxime does not degrade a fuel, e.g. heating fuel oil, diesel fuel and the like, upon storage. Fuel additives containing metal compounds to function, e.g., as an agent to reduce soot formation and generally improve the combustion properties of the fuel may be added to fuels and stored without the build-up of gummy deposits and sludge in the storage container.
