Alternative fuel for internal combustion engine, containing biobutanol

Abstract

The present invention relates to an alternative fuel composition for internal combustion engines comprising: 1˜88% by weight of biobutanol or a mixture of biobutanol and butanol, 3˜75% by weight of paraffinic hydrocarbon solvents, 3˜35% by weight of toluene, and 6˜30 % by weight of xylene, based on the total weight of the composition.

1 . A fuel composition for internal combustion engines comprising:
 a) 1˜88% by weight of biobutanol or a mixture of biobutanol and butanol,   b) 3˜75% by weight of paraffinic hydrocarbon solvents,   c) 3˜35% by weight of toluene, and   d) 6˜30% by weight of xylene,   based on the total weight of the composition.   
     
     
         2 . The fuel composition for internal combustion engines as set forth in  claim 1 , further comprising one or more component selected from the group consisting of 1˜85% by weight of aliphatic alkane and alicyclic alkane having 5 to 40 carbon atoms, 1˜43% by weight of kerosens, 1˜32% by weight of Hi-sene, 1˜36% by weight of Hi-nine, 0.1˜5% by weight of lubricant base oil, 1˜9% by weight of butyl cellosolve, 1˜11% by weight of ethyl cellosolve, 1˜13% by weight of isopropanol, 1˜12% by weight of isobutanol and 1˜19% by weight of aromatic hydrocarbon mixture, based on the total weight of the composition. 
     
     
         3 . The fuel composition for internal combustion engines as set forth in  claim 1 , further comprising 0.001˜6% by weight of rosin, rosin derivatives, and rosin acid or a mixture thereof. 
     
     
         4 . The fuel composition for internal combustion engines as set forth in  claim 1 , further comprising 0.01˜85% by weight of biodiesel.
