| Abstract: | An unsteady dynamic equation for hybrid turbochargering system in a vehicle diesel engine is developed,then small-signal linearization of nonlinear term is employed.The simulation result of transfer function in Simulink demonstrates that decreasing the rotational speed of turbocharger and the moment of rotating inertia of the turbocharger can enhance the unsteady response performance.The study shows the parameter adjustment of hybrid turbochargering system is reasonable. |
