The test is investigated magnitude of pressure pulsations in the SGMW B12 T255 fuel rail assembly and any effects on port to port flow distribution. The test bench is provided the fuel rail assembly required pressure and pulse width and period to simulate series of engine work status. The pressure pulsation results showed a significant change in the magnitude between 2000 and 3000 RPM. Flow distribution was further measured at 2000 RPM and 7ms, the finally test result is passed. After the vehicle test, it’s showed that reducing the flow rate from 1.8g/s to 1.5 g/s would further improve pulsation performance.
