Claims

exact text as granted — not AI-modified

1 . A fuel composition for a lean burn engine comprising hydrocarbons having 4 to 6 carbon atoms as main component, with an aromatic content of 25 vol % or less. 
     
     
         2 . The fuel composition for a lean burn engine according to  claim 1 , wherein the content of olefins having 4 to 6 carbon atoms is 20 to 60 vol % relative to the total amount of hydrocarbons having 4 to 6 carbon atoms. 
     
     
         3 . The fuel composition for a lean burn engine according to  claim 1 , wherein the content of normal paraffins having 4 to 6 carbon atoms is 20 vol % or less relative to the total amount of hydrocarbons having 4 to 6 carbon atoms. 
     
     
         4 . The fuel composition for a lean burn engine according to  claim 1 , wherein the content of hydrocarbons having 4 to 6 carbon atoms is 85 vol % or more.
