基于enDYDA的GDI发动机快速起动仿真研究
|
摘要
快速起动是怠速停止-起动技术中的关键。本文以GDI发动机为研究对象,基于enDYDA模型研究快速起动策略。通过对节气门的开度和点火提前角的调节,观察喷油点火的MAP图、发动机的速度以及起动时间,确定在什么情况能快速起动。
Fast starting is the key to idling stop—starting technology. This paper,taking GDI engine as the research object,discusses fast starting strategies based on enDYDA model. By adjusting the throttle opening and ignition advance angle,we determine the conditions for the rapid starting based on the observation of MAP graph of the fuel injection and ignition,the speed of the engine and the starting time.
