Toyota Mirai 2 - Compressor Analysis & Mapping

Content Compressor Testing:

- Compressor benchmarking of aerodynamics, acoustics and electronics

  • Setup on high tech FEV turbocharger test bench

  • Measurement of aerodynamic compressor map (ηC, ṁC, ΠC, nC)

  • Transient load steps to capture the NVH behavior of compressor and e-motor (acceleration and mic)

  • Power measurement (U, I, φ) to quantify e-motor

- System Mapping

  • Connect compressor assembly to appropriate power supply

  • Measurement of mass flow and pressure ratio under transient conditions

  • Evaluate efficiency via electric power consumption: 3-phase AC motor power

Deliverables:

- Test report incl. setup and results in *.pdf-format

- Aerodynamic compressor map (*.xlsx)

- Acoustic data (accelerometer on compressor and microphone) for mapping and speed sweep (*.xlsx)
