  1. The fuel system Fuel pumps Engine mu

  2. Fuel pumps Engine Types of fuels Diesel engines consume Heavy Fuel Oil (HFO), Marine Diesel oil (MDO) or Intermediate Fuel Oil (IFO). S

  3. Types of fuels HFO is a residual oil that is made suitable for driving Diesel engines by adding certain flammable substances. HFO MDO is a high-grade fuel of low viscosity that is used when the vessel is manoeuvring. MDO Modern Diesel engines are run on IFO, a fuel whose grade lies between that of HFO and MDO. IFO

  4. HFO HFO MDO Fuel pumps Engine HFO From the Heavy Fuel Oil bunkertank the preheated fuel is led to the settling tank. Settling tank

  5. HFO HFO MDO Fuel pumps Engine HFO In the settling tank water and impurities are separated from the fuel and drained off. Settling tank Drain-valve s

  6. HFO HFO MDO Fuel pumps Engine HFO From the settling tank the fuel is led through a heater to preheat the fuel.

  7. HFO HFO MDO Fuel pumps Engine HFO From the heater the fuel is led through a separator (purifier / clarifier) to purify the fuel.

  8. HFO HFO MDO Fuel pumps Engine HFO From the separator the fuel enters the daily service tank for HFO. sound

  9. HFO HFO MDO Fuel pumps Engine HFO There are two daily service tanks, so that one tank may be used while the other is being filled. Daily service tank Daily service tank sound

  10. HFO HFO MDO Fuel pumps Engine HFO From the daily service tank the fuel is pumped to a heater by the low pressure fuel pump (or “booster pump”). s

  11. HFO HFO MDO Fuel pumps Engine HFO From the heater the HFO is passed through a viscosity regulator .

  12. HFO HFO MDO Fuel pumps Engine HFO From the viscosity regulator the fuel is passed through a fuel strainer , which filters the fuel.

  13. HFO HFO MDO Fuel pumps Engine HFO From the fuel strainer the oil is led to the fuel pumps in the engine. sound

  14. HFO HFO MDO Fuel pumps Engine MDO Diesel oil is used for manoeuvring and is stored in the MDO bunkertank.

  15. HFO HFO MDO Fuel pumps Engine MDO After the DO has been pumped up from the bunkertank, the fuel passes through a purifier .

  16. HFO HFO MDO Fuel pumps Engine MDO From the purifier the DO enters the DO storage tank. s

  17. HFO HFO MDO Fuel pumps Engine MDO From the DO service tank the fuel is led to the high-pressure fuel pumps in the engine. s

  18. HFO HFO MDO Fuel pumps Engine A mixing tank is used for a gradual transition from HFO to DO. sound Mixing tank

  19. HFO HFO MDO Fuel pumps Engine The mixing tank, or “buffer tank”, can hold a quantity of fuel which will be circulated and led to the engine. Buffer tank (Circulating tank) sound

  20. HFO HFO MDO Fuel pumps Engine The hot fuel fumes can escape through the air vent in the mixing tank. s Air vent

  21. Test 2: Indicate whether the assertion is or Indicate in the textbox or in the IMLP-coursebook why you think the assertion is wrong. The fuel system

  22. Types of fuels HFO is a residual oil that is made suitable for driving Diesel engines by removing certain flammable substances. HFO …..because: MDO is a low-grade fuel of high viscosity that is used when the vessel is manoeuvring. MDO …..because: Modern Diesel engines are run on IFO, a fuel whose grade lies between that of HFO and MDO. IFO 1 right or wrong

  23. HFO HFO MDO Fuel pumps Engine From the Heavy Fuel Oil bunkertank the fuel is led to the settling tank. Settling tank 2 right or wrong

  24. HFO HFO MDO Fuel pumps Engine …..because: In the settling tank the fuel is drained off after it has been separated from water and impurities. Settling tank 3 right or wrong

  25. HFO HFO MDO Fuel pumps Engine …..because: From the settling tank the fuel is first led through a purifier and then through a separator. Settling tank 4 right or wrong

  26. HFO HFO MDO Fuel pumps Engine From the separator the fuel enters the daily service tank. Settling tank 5 right or wrong

  27. HFO HFO MDO Fuel pumps Engine …..because: There are two daily service tanks: one to preheat the fuel, the other to purify the fuel. Settling tank 6 right or wrong

  28. HFO HFO MDO Fuel pumps Engine From the daily service tank the fuel is pumped to a heater by the booster pump. Settling tank 7 right or wrong

  29. HFO HFO MDO Fuel pumps Engine …..because: From the heater the HFO is passed through a separator . Settling tank 8 right or wrong

  30. HFO HFO MDO Fuel pumps Engine …..because: A fuel strainer preheats and filters the fuel. Settling tank 9 right or wrong

  31. HFO HFO MDO Fuel pumps Engine …..because: From the fuel strainer the oil is led to the low pressure fuel pumps in the engine. Settling tank 10 right or wrong

  32. HFO HFO MDO Fuel pumps Engine …..because: Diesel oil is used for manoeuvring and is stored in three daily service tanks. Settling tank 11 right or wrong

  33. HFO HFO MDO Fuel pumps Engine After the DO has been pumped up from the bunkertank, it is passed through a purifier. Settling tank 12 right or wrong

  34. HFO HFO MDO Fuel pumps Engine …..because: From the purifier the DO enters the settling tank. Settling tank 13 right or wrong

  35. HFO HFO MDO Fuel pumps Engine …..because: From the DO service tank the fuel is led through a separator, heater, viscosity controller and strainer to the fuel pumps in the engine. Settling tank 14 right or wrong

  36. HFO HFO MDO Fuel pumps Engine …..because: A mixing tank is used to drain off water and impurities from the fuel. Settling tank Mixing tank 15 right or wrong

  37. HFO HFO MDO Fuel pumps Engine …..because: The hot fuel fumes can escape through the air vent into the mixing tank. Settling tank Mixing tank 16 sound right or wrong
