摘要
推出了混合涡轮增压系统的瞬态动力学方程,并对瞬态方程做小偏差线性化处理。在S imu link中,对混合涡轮增压系统的传递函数仿真,显示了增压器稳态转速和转动惯量的减小能提高增压系统的动态响应特性。仿真分析验证了对混合增压系统参数调整的合理性。
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.
