摘　　要：采用增压调节可实时精确地调整电控柴油机的增压压力,从而提高柴油机的比功率和燃油经济性。文中利用ETAS公司的ASCET软件进行增压调节系统的模块设计、自动代码生成和硬件在环仿真。试验结果表明,增压调节可实现对增压系统的闭环控制,加快系统的响应。最后通过优化,进一步改善系统的稳定性和可靠性。Adopting pressure charging regulation（PCR） can accurately adjust supercharging pressure in real time and hence raise the specific power and fuel economy of diesel engine.In this paper,ASCET software of ETAS Company is used to conduct module design,automatic code generation as well as hardware-in-the-loop simulation for PCR system.The results of test show that PCR can achieve close-loop control of supercharging system and thus speed up the response of system.Finally the stability and reliability of system are further improved through optimization.
