Figure 4.26 RFM Test in Progress
The injector has maximum pressure applied, with no injection pulse.
Observe the flow measurement on the backleak flow indicator.
The test assessment is purely visual. There are no pass/fail indications on-screen that the injector is
acceptable or not. The operator must determine by observation and comparison with a known ‘good’
injector, whether the backleakage (return) flow is acceptable. In an ideal injector, the flow in this test
would be zero.
