基于OSEKWorks开发平台的高压共轨喷油控制系统的研究

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．

务操作系统OSEKWorks，不仅有效提高了软件的开发效率，而且也提高了软件的质量和可靠
性。通过合理的任务划分和基于优先级的抢占式调度方式，提高了CPU的利用率，确保了电
控喷油系统的实时性要求，有效提高了发动机的动态响应性能。实践证明，在高压共轨电控喷油系统引入多任务实时操作系统，是确保高压共轨电控喷油系统精确、可靠运行的关键，是提高柴油机性能的一个行之有效的途径。
