| 摘 要： | 建立了柴油机可控启喷压力喷油器燃油喷射系统液力模型,并进行仿真计算;利用CB-466燃烧分析仪测试该燃油喷射系统的喷油器针阀升程和喷油器端高压油管燃油压力,与仿真计算结果对比,验证了仿真模型和计算方法的可信性;在此基础下就不同启喷压力下柴油机喷油特性进行了预测研究。结果表明:启喷压力增大使得喷油延迟,喷油压力增大,燃油的喷雾质量改善。

| Abstract: | A hydraulic simulation model was applied to the fuel injection system of diesel engine with controllable fuel starting injection pressure,and used to simulate injection process.The injector needle lifts and the injection pressure of high pressure fuel pipe at the injection end were recorded through expe-riments of the pressure fuel injection system with CB-466 combustion analyzer and brought into comparison with the computed results,thus verifies the simulation model and calculation method.Then,the model wa... |
