Possible Causes

  • •Fuel injection system fault
  • •Turbocharger failure
  • •Cooling system (V-12 dual-bank) failure
  • •Fuel quality degradation
  • •Tank degradation
  • •Stagnant fuel
  • •Starting system (24V battery bank) failure
  • •Infrequently exercising the unit
  • •Catalyst degradation
  • •Spark plugs (multi-cylinder)
  • •Gas regulator / air-fuel mixer
  • •Ignition system (coils / module)
  • •Catalytic converter
  • •Turbocharger
  • •Turbocharger fault
  • •Cooling system fault (V-12 dual-bank)
  • •Starting system fault (24V battery bank)
  • •Infrequently exercised unit
  • •Catalytic converter degradation
  • •Spark plugs (multi-cylinder) failure

Suggested Actions

  1. 1Perform periodic backpressure testing on the catalytic converter
  2. 2Perform periodic calibration of the mechanical injection system
  3. 3Inspect turbocharger condition
  4. 4Inspect cooling circuit integrity
  5. 5Inspect injector pump condition
  6. 6Assess overall platform health and flag components approaching end-of-life
  7. 7Size gas regulator with at least 2x capacity margin for the peak flow demand
  8. 8Ensure gas regulator sizing provides at least 2x capacity margin for the peak flow demand
  9. 9Maintain LT inlet below 50C
  10. 10Consult altitude and temperature derating tables for adjustment
  11. 11Consult factory for adjusted ratings if Methane Index is below 55
  12. 12Implement oil analysis programs to extend drain intervals
  13. 13Schedule spark plug service intervals carefully
  14. 14Use OEM-specified plugs
  15. 15Use InPower service tool for per-cylinder monitoring
  16. 16Annual load-bank testing of the starting circuit under simulated cranking conditions
  17. 17Ensure both batteries meet the minimum 1800 CCA requirement individually
  18. 18Confirm with the utility or gas supplier that dynamic pressure at the engine inlet remains within 10-20 in WC at full load
  19. 19Ensure gas regulator sizing provides at least 2x capacity margin for peak flow demand
  20. 20Maintain gas supply pressure between 2.9 - 6.7 psi (0.2 - 0.46 bar)
