Abstract

The emission from high pressure common rail fuel system compressor ignition engines is reduced by using fuel in said engine a diesel fuel characterized as having a sulfur content of about 0.05 wt % or less, a density of about 0.83 or less and a viscosity of about 3 cSt or less at 40° C.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
         1 . A method for reducing emissions of common rail fuel system compression ignition engine by running said engine on a fuel comprising a diesel fuel characterized by having a density of about 0.83 g/cc or less and a viscosity of about 3 cSt or less at 40° C.  
     
     
         2 . The method of  claim 1  wherein the diesel fuel is characterized by having a density of about 0.825 g/cc or less.  
     
     
         3 . The method of  claim 1  wherein the diesel fuel is characterized by having a density of about 0.820 g/cc or less.  
     
     
         4 . The method of  claim 1  wherein the diesel fuel is characterized by having a viscosity of about 2.6 cSt or less at 40° C.  
     
     
         5 . The method of  claim 2  wherein the diesel fuel is characterized by having a viscosity of about 2.6 cSt or less at 40° C.  
     
     
         6 . The method of  claim 3  wherein the diesel fuel is characterized by having a viscosity of about 2.6 cSt or less at 40° C.  
     
     
         7 . The method of  claim 1  wherein the diesel fuel is characterized by having a viscosity of about 2.1 cSt or less at 40° C.  
     
     
         8 . The method of  claim 2  wherein the diesel fuel is characterized by having a viscosity of about 2.1 cSt or less at 40° C.  
     
     
         9 . The method of  claim 3  wherein the diesel fuel is characterized by having a viscosity of about 2.1 cSt or less at 40° C.  
     
     
         10 . The method of  claim 1 ,  2 ,  3 ,  4 ,  5 ,  6 ,  7 ,  8  or  9  wherein the diesel fuel is characterized by having a sulfur content of about 0.05 wt % or less.  
     
     
         11 . The method of  claim 10  wherein the diesel fuel is characterized by having a sulfur content of about 0.04 wt % or less.  
     
     
         12 . The method of  claim 10  wherein the diesel fuel is characterized by having a sulfur content of about 0.03 wt % or less.
