[EN] The present paper deals with the influence of fuel properties on the spray behaviour. This influence was studied
experimentally using a common rail injection system from a medium speed diesel engine. The experiments have
been performed with diesel fuel (EN-590) and heavy fuel oil (RMG 180) on a constant volume chamber at room
temperature. Comparison of the spray characteristics shows that the heavy fuel oil penetrates deeper in the
chamber. However, the diesel spray has a bigger cone angle. These results formed the basis for a further
development of the 1D-model [1] to predict the spray penetration by considering the fuel properties and temperature.
