An engine will produce radiated heat - approximately
equal to
1
/
3
of the engine output power. Additionally, the
starter battery alternator and generating set AC alternator
create heat, building ambient temperatures further.
As a consequence, it is highly important and the vessels
owner and/or installation engineer/s are responsible
to ensure that the engine compartment has adequate
ventilation to enable efficient internal combustion,
effective transference of heat out of the engine
compartment/room and prevent the accumulation of
gases, which might be emitted from starter batteries.
Best practice for efficient and effective ventilation is an
air intake that is located in the engine compartment/
room that is as low as possible, allowing cooler air to
enter below the generating set engine and AC electrical
alternator and an air outlet with an electric powered
extraction fan which should be located as high as possible
in the engine compartment/room maximising ventilation
and reducing ambient temperatures.
The cooler the engine compartment/room can be
maintained the more efficient the engine will perform.
