In the present paper, an analysis of non-evaporating, transient Diesel sprays generated by an automotive common-rail, electronic controlled injection system is described. A standard Diesel fuel and a pure Biodiesel were used for the tests, with sprays evolving in a pressurized test chamber and generated by both cylindrical and conical hole nozzles. The spray analysis is performed mainly by means of a laser sheet technique in order to obtain global spray data suitable for tuning direct injection systems to such fuels and for numerical codes validation. A dispersion analysis among different jets was also performed, along with the injection rate measurement. A PDA system was also used to characterize the behavior of the two fuels with the prototype injector nozzles at ambient conditions.
