One-dimensional modeling and simulation of injection processes of bioethanol-biodiesel and bioethanol-diesel fuel blends

The derived model is used to simulate the injection processes of various bioethanol-biodiesel and bioethanol-diesel fuel blends. The simulation results are compared to experimental data obtained on a Friedman-Maier type 12H100_h test bed at ambient temperature and several operating regimes. The results show that the compared injection pressure and needle lift histories are generally in a good agreement with the experimental ones. Consequently, the simulation model presented is fast and accurate enough to be engaged in various numerical procedures, ranging from investigations of influences of bioethanol addition to injection system optimization.
