摘　　要：通过售后市场以及开发过程中的反馈,PFI涡轮增压发动机存在超级爆震现象,故本文基于某PFI涡轮增压发动机的控制理论和策略研究发动机管理系统对于超级爆震信号监测的有效性,控制理论以及控制策略的合理性,控制策略对发动机的保护能力是否足够以及对发动机性能与排放的负面影响是否可以接受。目前从理论研究可以得出结论,通过大量科学的试验,发动机管理系统能够有效控制超级爆震,对发动机做出有效的保护,排放与性能的负面影响能够降至较低水平。According to the feedbacks from the aftermarket and the development projects,the turbocharged PFI gasoline engines have the phenomenon of super knock. So,based on the control theories and strategies of a turbocharged PFI engine,we explore the effectiveness of the detections of Super Knock signal,the rationality of the control theories and the control strategies,also need to confirm the abilities of control strategies to protect the engine,and the negative impacts on the engine performances and emissions. From the theoretical studies,it can be concluded that through a large number of scientific tests,the engine management system can effectively control the super knock and make effective protection for the engine,and the negative impacts on emissions and performance can be reduced to a low level.
