There is a tendency to use biodiesel (methyl ester of rapeseed oil in particular), rapeseed oil and their blends with diesel as an alternative fuel for diesel engines. The mathematical modelling of the fuel spray is a wide-spread approach lo facilitate the problem solving in this area. The paper studies three types of the models, namely Sazhin's model, Reitz's wave breakup model, and Lishevsky's model. For the models, the relationship between respective model parameters has been defined and the parameter's values have been calculated using experimental data. Given the values, some main spray characteristics have been computed. Based on the characteristics' values, an evaluation of the models has been performed and the following conclusions have been made: (1) the models discussed do not enable to compute all characteristics needed all together; (2) some models do not indicate the increase of the spray penetration for rapeseed oil and biodiesel in comparison with diesel; (3) in case of biodiesel, it seems promising to develop a hybrid model based on the wave breakup model and using empirical formulae of Lishevsky's model. For rapeseed oil, the possibility to employ the models discussed should be studied further and will probably require more experimental data.
