Definitions
- This invention relates to a diesel fuel additive and a diesel fuel composition comprising same. More particularly, the invention relates to the inhibition of deposit formation in the fuel injectors of diesel fueled engines by incorporation into said fuel of a composition comprising a polyalkenyl succinic acid.
- Fuel injectors are used in both gasoline and diesel fueled engines but the mechanism for inhibiting deposit formation within and around the orifices of the fuel injectors in such engines are quite different because of the quite distinct difference in the composition of gasoline and diesel fuels.
- the present invention which provides a polyalkenyl succinic acid additive which inhibits the formation of deposits in injection systems for diesel fueled engines.
- U.S. Patent No. 2,993,772 discloses a process for inhibiting the formation of deposits in internal combustion engines which comprises adding to the fuel an additive which is an ester of an alkenyl succinic acid having 8 to 31 carbon atoms in the alkenyl group and an alcohol.
- U.S. Patent No. 3,117,091 discloses a rust preventive compound for various fuels which is a partial ester of an alkenyl succinic anhydride and a polyhydric alcohol.
- Patent 3,346,354 discloses a hydrocarbon fuel composition capable of reducing intake valve and port deposits, which fuel contains an alkenyl succinic acid or an alkenyl succinic ester.
- U.S. Patent No. 3,447,918 discloses the use of polybutene substituted succinic acid as a corrosion inhibitor for distillate fuels.
- U.S. Patent No. 3,574,574 discloses a motor fuel composition which reduces intake valve and port deposits which contains a polyester or a polymerized carboxylic acid.
- the present invention relates to an additive for inhibiting deposit formation in the fuel injectors of diesel fueled engines.
- the additive is a polyalkenyl succinic acid having a molecular weight (number average) of from about 200 to about 350 and which is represented by the following general structural formula: wherein R is an alkenyl radical.
- the alkenyl radical may be straightchained or branch-chained and contains from about 8 to about 20 carbon atoms.
- Examples of such compounds are tetraethenyl succinic acid, octenyl succinic acid, nonenyl succinic acid, decenyl succinic acid, undecenyl succinic acid, tetrapropenyl succinic acid, dodecenyl succinic acid, 3-butyloctenyl succinic acid, tetrabutenyl succinic acid, hexadecenyl succinic acid, didecenyl succinic acid and the like.
- alkenyl succinic acids used in the present invention are prepared by the simple hydrolysis of the corresponding anhydride, as is conventional and well-known to those skilled in the art. Since relatively pure olefins are difficult to obtain, alkenyl succinic acids are usually prepared as mixtures by reacting mixtures of olefins with moleic acid anhydride. Such mixtures, as well as pure anhydrides, are utilizable herein.
- the alkenyl succinic acid additives of the present invention are added to the diesel fuel neat or as a solution of the acid in an appropriate solvent, e.g., a hydrocarbon solvent, and may be used in combination with other diesel fuel additives such as surface active agents, film formers, oxygen scavengers, corrosion inhibitors, dehazers and the like.
- an appropriate solvent e.g., a hydrocarbon solvent
- the useful concentration of the additive is from about 30 parts to about 600 parts additive per million parts diesel fuel, preferably from about 75 parts to about 300 parts additive per million parts diesel fuel, especially from about 100 parts to about 200 parts additive per million parts diesel fuel.
