Abstract

Fuel compositions comprising primarily diethyl succinate as an oxygenation additive are described. The fuels can be diesel fuels which generate carbon based particulates in diesel engines. The result is reduced emissions of particulates from the diesel engines.

Claims

exact text as granted — not AI-modified
I claim:  
     
         1 . A composition which comprises: 
 (a) a liquid hydrocarbon fuel; and    (b) between 0.1 and 30 percent by weight of diethyl succinate as a primary organic oxygenation source for the fuel.    
     
     
         2 . The composition of  claim 1  wherein the fuel is diesel fuel.  
     
     
         3 . The composition of  claim 1  wherein the diethyl succinate is 5 to 10 percent by weight of the fuel.  
     
     
         4 . The composition of any one of claims  1 ,  2  or  3  wherein the fuel is substantially free of contaminants which cause pollution.  
     
     
         5 . A method for increasing combustion of a fuel to water and carbon dioxide, and reducing particulates from the combustion, which comprises: 
 providing a composition which comprises a liquid hydrocarbon as the fuel and between 0.1 and 30 percent by weight of diethyl succinate as a primary organic oxygenation source to run the engine so as to increase the combustion and reduce the particulates from the combustion.    
     
     
         6 . The method of  claim 5  wherein the fuel is diesel fuel.  
     
     
         7 . The method of  claim 5  wherein the diesel fuel is 5 to 10 percent by weight of the fuel.  
     
     
         8 . The method of any one of claims  5 ,  6  or  7  wherein the fuel is substantially free of contaminants which cause pollution.  
     
     
         9 . The composition of any one of claims  1 ,  2  or  3  wherein the diethyl succinate is the sole organic oxygenation source for the fuel.  
     
     
         10 . The method of any one of clams  5 ,  6  or  7  wherein the diethyl succinate is the sole organic oxygenation source for the fuel.
