This review will be concentrated on the spray characteristics of biobutanol and its blends fuels in internal combustion engines including compression ignition,spark ignition and gas turbine engines.Butanol can be produced by fermentation from sucrose-containing feedstocks,starchy materials and lignocellulosic biomass.Among four isomers of butanol,n-butanol and iso-butanol has been used in CI and SI engines.This is due to higher octane rating and lower water solubility of both butanol compared with other isomers.The researches on the spray characteristics of neat butanol can be classified into the application to CI and SI engines,particularly GDI engine.Two empirical correlations for the prediction of spray angle for butanol as a function of Reynolds number was newly suggested.However,the applicability for the suggested empirical correlation is not yet proved.The butanol blended fuels used for the investigation of spray characteristics includes butanol-biodiesel blend,butanol-gasoline blend,butano-jet A blend and butanol-other fuel blends.Three blends such as butanol/ethanol,butanol/heptane and butanol/heavy fuel oil blends are included in butanol-other fuel blends.Even though combustion and emission characteristics of butanol/diesel fuel blend in CI engines were broadly investigated,study on spray characteristics of butanol/diesel fuel blend could not be found in the literature.In addition,the more study on the spray characteristics of butanol/gasoline blend is required.
