【Abstract】 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.更多还原
