3.5 COOLING WATER CIRCUIT
The generator engine is cooled by an open-circuit
systemin which seawater circulates.
At the time of installation, a seawater feed circuit
must be arranged for cooling, and an exhaust system
for the combustion gas and water mixture.
3.5.1 SEAWATER FEED SYSTEM
Two water intake systems are normally adopted on
boats:
-Direct intake system (ref.1).
-Systemwith baffle (ref.2).
Manufacturer recommends using the direct intake
system (ref.1), since it prevents intake of pressurised
water into the intake ducts, instead generatinga vacuum
easily overcome by the water pump head of the
generator.
Do not fit any type of protection cap on the direct
intake system.
The system with baffle (ref.2), on the other hand, may
cause the following problems:
a- If mounted with the slots facing the bow:
In this case, during navigation and with the generator
off, pressure is created in the water intake duct, which
may cause the systemto fill upuntilreachingthe exhaust
port, thus making it possible for water to enter the
cylinders.
b- If mounted with the slots facing the stern:
In this case, duringnavigation a vacuum may be created
in the water intake duct such as to inhibit the water pump
to activate the cooling system or such as to limit the
flow rate with consequent overheating ofthe generator.
