基于OSEKWorks開發(fā)平臺的高壓共軌噴油控制系統(tǒng)的研究

Abstract：This paper introduced the embedded real—time operation system into the study of high pressure common rail fuel inj ection system．Using the real—time multitask operation system OSEKWorks not only
effectively improved the efficiency of software development but also improved the quality and reliability of the
developed software．Using the proper partition of task and scheduling mechanism based on priority improved
the efficiency of CPU．insured the need of real-time capability of electronic control fuelinjection system and
improved the transient response of diesel engines．The experiment proved that introducing multitask realtime operation system into high—pressure common rail electronic control fuel injection system is the key tech_nic that can insure the system running accurately and reliably．
