摘　　要：在现有的某型号天然气发动机电控调压器基础上,建立电控调压器的AMESim模型,对该模型进行了详细的说明,并进行了静态和动态仿真。从仿真结果可以看出,该模型在动态下反应时间较短。通过燃气压力和流量实验验证了该模型的准确性。针对南充NQ120天然气发动机对燃气压力和流量的需求,对原调压器结构参数进行优化,得到能够满足需要的调压器结构参数。The model of EPR for CNG-engine was built based on AMESim. The static and dynamic performances of the EPR were simulated. It is shown that the dynamic response time is shorter. The accuracy of the model was verified by experiment. To meet the needs of pressure and mass flow rate of NQ120 CNG-engine, the original parameters were optimized.
