dSPACE XSG Injector Emulation Interface Solution

火花点火式发动机的高精度喷油系统测试

dSPACE提供XSG Injector Emulation Interface Solution,用于测试火花点火式发动机的高精度喷油系统。

利用最先进的喷油系统能够评估喷射器线圈的关闭特性,实现精确的喷射。这通过测量喷油器的电流和电压分布来完成。由于特殊的关闭特性,传统的更换负载或真实喷射器不足以测试这些新的喷油系统。这就是 dSPACE开发XSG Injector Emulation Interface Solution的原因,它可以与SCAXEXIO系统一起使用。

主要功能

  • 每个喷油器的FPGA板卡(DS2655)和电子负载模块(EV1139)对连接到电子发动机控制单元(EECU)的喷油器进行实际电流和电压的模拟;
  • 计算喷油器行为 FPGA 模型
  • 支持电气故障仿真测试,比如短路和电缆断路测试。
  • 允许生成功能故障,以评估不同类型的信息,从系统行为到发射值都包括在内。

Parameter Specification
Emulation of the injector current flow
  • Parameterizable injector coil circuit (resistance, inductance incl. saturation effects and hysteresis)
  • Injection time measurement
Emulation of the feedback voltage in the closing phase
  • Look-up table (LUT)-based feedback voltage emulation, depending on:
    • Injection time
    • Rail pressure
Fault simulation
  • Defective injector (Failure LUT)
  • Ahead-of-time valve closing
  • Delayed valve closing
  • Ramp closing (instead of LUT)
Run-time tunability
  • All parameters can be changed during run time.
