Abstract
A diesel fuel composition comprising a major amount of hydrocarbons boiling in the diesel range and an effective lubricity enhancing amount of a salt of an alkyl hydroxyaromatic compound and an aliphatic amine, wherein the salt has the formula: ##STR1## wherein R is alkyl of 6 to 25 carbon atoms; R.sub.1 is alkyl or alkenyl of 6 to 50 carbon atoms; and X is hydrogen, hydroxy or the group --O.sup.- H.sub.3 N.sup.+ --R.sub.2, wherein R.sub.2 is alkyl or alkenyl of 6 to 50 carbon atoms.
Claims28
A diesel fuel composition comprising a major amount of hydrocarbons boiling in the diesel range and an effective lubricity enhancing amount of a salt of an alkyl hydroxyaromatic compound and an aliphatic amine, wherein the salt has the formula:
- ##STR4## wherein R is alkyl of 6 to 25 carbon atoms;
- R.sub.1 is alkyl or alkenyl of 6 to 50 carbon atoms;
- and X is hydrogen, hydroxy or the group --O.sup.- H.sub.3 N.sup.+ --R.sub.2, wherein R.sub.2 is alkyl or alkenyl of 6 to 50 carbon atoms wherein the diesel fuel composition contains not more than 0.2 weight % of sulfur.
A method for reducing the wear rate in the injection system of a compression ignition diesel engine which comprises operating the engine with a diesel fuel composition comprising a major amount of hydrocarbons boiling in the diesel range and an effective lubricity enhancing amount of a salt of an alkyl hydroxyaromatic compound and an aliphatic amine, wherein the salt has the formula:
- ##STR5## wherein R is alkyl of 6 to 25 carbon atoms;
- R.sub.1 is alkyl or alkenyl of 6 to 50 carbon atoms;
- and X is hydrogen, hydroxy or the group --O.sup.- H.sub.3 N.sup.+ --R.sub.2, wherein R.sub.2 is alkyl or alkenyl of 6 to 50 carbon atoms wherein the diesel fuel composition contains not more than 0.2 weight % of sulfur.
