摘　　要：相继增压技术有效地提高了高压比柴油机在部分负荷时的性能,然而,相继增压系统切换过程的瞬态性能比较复杂,需要深入地研究.基于Simulink/Matlab软件平台建立了相继增压柴油机线性化仿真模型,并对其进行了动态仿真.通过仿真计算,能很方便地了解柴油机各性能参数之间的变化关系.The sequential turbocharging technique is used to improve the performance of high pressure_ratio diesel engines in particular at part loads. However, the transient behaviour of the sequential turbocharging connection/disconnection is complex and requires an deep study. A linearized simulation model is established for the sequentially turbocharged diesel engine with Simulink/ Matlab language and dynamic simulation is performed.The change of parameters of diesel engine can be easily investigated through simulation results.
