喷油器特性对共轨燃油喷射系统的性能及其对柴油机燃烧的影响有很大的影响。共轨喷油系统的喷油定时和喷油速率是影响发动机燃烧控制和污染物形成机理的重要因素。建立了高速直喷式柴油机共轨喷油器的动态模型，介绍了喷油器喷油定时和喷油速率的估算方法。数值仿真和实验结果表明，所提出的滑模观测器（SMO）可以有效地估计共轨喷油器的喷油定时和喷油速率。
The performance of a common-rail fuel injection system and its effects on diesel engine combustion are strongly influenced by the injector characteristics. The injection timing and the injection rate of the common-rail injection system are important factors for combustion control and pollutant formation mechanism during the engine operation. This paper presents a dynamic model of the common-rail injector for high speed direct injection (HSDI) diesel engines and introduces a methodology for estimating the injection timing and the injection rate of the injector. The numerical simulation and the experimental results show that the proposed sliding mode observer (SMO) can effectively estimate the injection timing and the injection rate of the common-rail injector.
