The fuel system


Слайд 2S
Diesel engines consume Heavy Fuel Oil (HFO),
Marine Diesel Oil (MDO) or

Intermediate Fuel Oil (IFO).

Слайд 3

MDO
IFO
Modern Diesel engines are run
on Intermediate Fuel Oil (IFO),
a

fuel whose grade lies between that of
HFO and MDO.


HFO

Types of fuels

Heavy Fuel Oil is a residual oil that
can be made more suitable for driving
Diesel engines by adding certain
flammable substances.

Marine Diesel Oil (MDO) is a
high-grade fuel of low viscosity.


Слайд 4From the Heavy Fuel Oil bunkertank
the preheated fuel is led to

the settling tank.

HFO


Слайд 5s
In the settling tank water and impurities are separated from the

fuel and drained off.

HFO


Слайд 6From the settling tank the fuel is led through a
heater

to preheat the fuel.




HFO


Слайд 7From the heater the fuel is led through a separator (purifier

/ clarifier) to purify the fuel.




HFO


Слайд 8sound
From the separator the fuel enters the
daily service tank for

HFO.



HFO


Слайд 9sound
There are two daily service tanks, so that one tank may

be used while the other is being filled.

Слайд 10s
From the daily service tank the fuel is pumped to a

heater by the low pressure fuel pump (or “booster pump”).





HFO


Слайд 11From the heater the HFO is passed through a viscosity regulator

.




HFO


Слайд 12From the viscosity regulator the fuel is passed through a fuel

strainer , which filters the fuel.




HFO


Слайд 13sound
From the fuel strainer the oil is led to the fuel

pumps in the engine.

Marine Diesel Oil


Слайд 15After the DO has been pumped up from the bunkertank, the

fuel passes through a purifier .




MDO


Слайд 16s
From the purifier the DO enters the
DO storage tank.


MDO


Слайд 17s
From the DO service tank the fuel is led to the

high-pressure fuel pumps in the engine.



MDO


Слайд 18 sound
A mixing tank is used for a gradual

transition from HFO to DO.

Слайд 19 sound
Buffer tank

(Circulating tank)
The mixing tank, or

“buffer tank”, can hold a quantity of fuel which will be circulated and led to the engine.




Слайд 20 s
The hot fuel fumes can escape throughthe

air vent in the mixing tank.
