起动过程控制策略是发动机控制的核心内容之一。本文利用AMESim软件建立电控单体泵供油系统模型和ECU控制模型，设计电控单体泵燃用二甲醚的起动过程控制策略，对起动喷油量及喷射正时进行精确控制。
起動過程控製策略是髮動機控製的覈心內容之一。本文利用AMESim軟件建立電控單體泵供油繫統模型和ECU控製模型，設計電控單體泵燃用二甲醚的起動過程控製策略，對起動噴油量及噴射正時進行精確控製。
기동과정공제책략시발동궤공제적핵심내용지일。본문이용AMESim연건건립전공단체빙공유계통모형화ECU공제모형，설계전공단체빙연용이갑미적기동과정공제책략，대기동분유량급분사정시진행정학공제。
Control strategy of start-up process action is one of the key technology in engine control. Based on AMESim, the authors construct the models of the fuel injection and the ECU control of the electronic unit pump, and design the control strategy of start-up process with electronic unit pump for DME engine, which can accurately con-trol the fuel quantity, injection timing and injection period.
