Diesel fuel composition

Abstract

A fuel composition is disclosed comprising a major amount of hydrocarbons boiling in the diesel range and an effective deposit-controlling amount of at least one stability additive or at least one antioxidant additive or mixtures thereof, and wherein the fuel composition contains no more than 30 ppm of active detergent additive or active dispersant additive or mixtures thereof.

What is claimed is: 
     
         1 . A fuel composition comprising a major amount of hydrocarbons boiling in the diesel range and an effective deposit-controlling amount of at least one stability additive or at least one antioxidant additive or mixtures thereof, and wherein the fuel composition contains no more than 30 ppm of active detergent additive or active dispersant additive or mixtures thereof. 
     
     
         2 . The fuel composition according to  claim 1 , wherein the fuel composition contains no more than 20 ppm of active detergent additive or active dispersant additive or mixtures thereof. 
     
     
         3 . The fuel composition according to  claim 1 , wherein the fuel composition contains about 10 to 200 weight ppm of the stability additive. 
     
     
         4 . The fuel composition according to  claim 3 , wherein the fuel composition contains about 100 to 200 weight ppm of the stability additive. 
     
     
         5 . The fuel composition according to  claim 1 , wherein the stability additive is an amine-phenolic resin. 
     
     
         6 . A method of reducing injector deposits in a direct injection diesel engine comprising supplying a fuel composition comprising a major amount of hydrocarbons boiling in the diesel range and an effective deposit-controlling amount of at least one stability additive or at least one antioxidant additive or mixtures thereof, and wherein the fuel composition contains no more than 30 ppm of active detergent additive or active dispersant additive or mixtures thereof to an internal combustion engine. 
     
     
         7 . The method according to  claim 6 , wherein the fuel composition contains no more than 20 ppm of active detergent additive or active dispersant additive or mixtures thereof. 
     
     
         8 . The method according to  claim 6 , wherein the fuel composition contains about 10 to 200 weight ppm of the stability additive. 
     
     
         9 . The method according to  claim 8 , wherein the fuel composition contains about 100 to 200 weight ppm of the stability additive. 
     
     
         10 . The method according to  claim 6 , wherein the stability additive is an amine-phenolic resin.
