The rubber impeller-type pump is driven by gears. Do not operate it without s e a v ^ f ,
due to damage the impeller.
• O i i cooler
This heat exchanger cools high temp, engine oil by seawater.
•Turbocharger
The pressurized intake air feeding device: the exhaust gas turbine » rotateo oy
the exhaust gas, and the power is used to rotate the blower.
This pressurises the intake air for sending to the cylinaer.
•Inter-cooler
This heat exchanger cools the pressurized intake air from the turbocharger with
seawater.

eve nt ttu*
The anti-corrosive zinc is itself reduced overtime by electncal oomxjor. so t m u a oe
replaced at fixed intervals before it is completely consumed m-order to ensure that the
metal area of the seawater cooling system remains fully protected.
