To meet more stringent norms and standards concerning engine performances and emissions, engine manufacturers need to\ndevelop new technologies enhancing the nonpolluting properties of the fuels. In that sense, the testing and development of\nalternative fuels such as biodiesel are of great importance. Fuel testing is nowadays a matter of experimental and numerical work.\nResearches on diesel engine�s fuel involve the use of surrogates, for which the combustion mechanisms are well known and relatively\nsimilar to the investigated fuel. Biodiesel, due to its complex molecular configuration, is still the subject of numerous investigations\nin that area. This study presents the comparison of four biodiesel surrogates, methyl-butanoate, ethyl-butyrate, methyl-decanoate,\nand methyl-9-decenoate, in a 0D phenomenological combustion model. They were investigated for in-cylinder pressure, thermal\nefficiency, andNO
