Fuel System Test Capacity at 99% fuel-test bench uptime: a worked example

This scenario runs the fuel system test capacity calculation on the strong side: 99% fuel-test bench uptime, with every other input held at its documented default. a test team needs realistic fuel-system test throughput to confirm the bench can keep up with engine builds

The inputs for this scenario

  • Fuel systems tested per cycle: 6 units / cycle (unchanged)
  • Available fuel-test cycles: 420 cycles (unchanged)
  • Fuel-test bench uptime: 99 % (raised for this scenario; the documented default is 92)
  • Fuel-test pass rate: 95 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross fuel-test throughput = fuel systems tested per cycle × available fuel-test cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 2,370 units for good fuel systems tested per shift, the number this scenario is built around.
  • At this operating point the engine returns 2,520 units for gross fuel-test throughput.
  • At this operating point the engine returns 25.2 units for fuel-test downtime loss.
  • At this operating point the engine returns 125 units for fuel-test retest loss.

How this compares with the baseline

  • Against the tool's baseline example, where fuel-test bench uptime sits at 92% and the headline result is 2,202 units, this scenario comes in 7.61% above the baseline at 2,370 units.
  • Use it when sizing a fuel-test cell, planning a production ramp, or quantifying how downtime and retests erode certified output. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Good fuel systems tested per shift: 2,370 units (headline result)
  • Gross fuel-test throughput: 2,520 units
  • Fuel-test downtime loss: 25.2 units
  • Fuel-test retest loss: 125 units
