Abstract

Using the comparison of experiments, we analyzed the diesel injector nozzle and its main characteristics. With the aid of engineering software, AVL FIRE, we can simulate the different operating conditions and analyze the development of cavitation and erosion in the injector channel. By varying the initial conditions - initial pressure, initial temperature and injection needle elevation, it is possible to identify variations in the injected fuel range, penetration and involved phases.
