abstract

In this paper one turbocharger for simulating its performance has been modeled in unsteady state. Our model subject to find out state space differential equations of system which contains different subsystems such as compressor, IC engine, turbine, fuel injection system, nozzle and shaft dynamics. We use bond graph method for modeling this system especially because our system is complex of components and stages additionally each subsystem has nonlinear performance. Whereas this system is base on Energy distribution in all elements. First we drew our system bond graph then according to bond graph we have found our state equations that will be simulated with use of initial conditions. In the end of this paper variability of pressure, temperature, rotational speed and pressure history in each stage according to time will be showed. In validation of results we have used references.
