Specific Fuel Oil Consumption

Inside this lesson
  • Define Specific Fuel Oil Consumption (SFOC) as fuel mass flow divided by brake power
  • Compute SFOC in g/kWh from a fuel-burn rate and brake power
  • State representative SFOC ranges for modern slow-speed two-strokes (as figures, not fixed values)
  • Explain why SFOC varies with load, fuel grade, and ambient conditions
