摘要 首先根据内燃机进排气系统一维非定常流动模拟计算"有限体积法-总变差减少"程序,建立柴油机两级和三级大小相继涡轮增压系统模拟计算程序。然后利用模拟计算程序对两级和三级大小相继增压系统进行研究。研究表明:采用三级大小相继涡轮增压系统优于两级相继涡轮增压系统。 According to the FVM-TVD simulating program for one-dimensional unsteady flow in inlet and outlet manifold of ICE, the sim and three-staged sequential turbocharging system is built. According to the simulating computation program, two-staged and three-staged sequential turbocharging system is studied on the diesel engine. The result demonstrates that three-staged sequential turbocharging system is better than two-staged sequential turbocharging system.
