摘　　要：为了解决高压共轨柴油机高海拔标定问题,采用基于模型的虚拟标定技术,建立了高压共轨柴油机基于模型的高海拔标定系统。在该标定系统的基础上,完成了试验设计、虚拟试验、模型构建、数据优化和脉谱生成等过程,获得了高压共轨柴油机循环喷油量、共轨压力和喷油定时的大气压力修正脉谱。基于模型的标定技术的应用,减少了高压共轨柴油机高海拔标定的工作量,缩短了开发周期,降低了开发成本。To solve the calibration problem of high pressure common rail diesel engine at high altitude, the paper establishes model-based calibration system with virtual calibration technology. With this system, the experiment design, virtual experiment, model construction, data optimization and map generation were conducted, and the injection quantity, common rail pressure and injection timing pressure corrected maps were acquired. The application of model-based calibration technology decreased the workload of high pressure common rail diesel engine high altitude calibration, shortened the development period, and reduced the development cost.
