With diesel engines
large amounts of
air are required
to p erform the
c o m b u s t i o n
process. Th
e higher
the revolutions
per minute of the
engine the more air is required to meet the demand.
Since diesels compress the air at a much higher ratio
than similiar gasoline models that require a spark in the
process the chance of explosion or fi re is much lower
with diesel power. Th
erefore, it is not necessary to force
the exhaust from the sump with a powered ventilation
system like the gas engine.
Diesel engines exhaust large amounts of incoming air by
mixing it through the combustion process and forcing
the air through the engine exhaust system into the water.
Th
e same deck cowlings are used to funnel incoming
air for combustion. Th e remaining air exits through the
cowlings into the atmosphere.
Th
is “breathing cycle” occurs naturally within the diesel
with more oxygen being required as the throttle speeds
are increased.
As part of diesel maintenance, ensure the cowlings are
free of debris including animal nests such as wasps and
birds. Check and replace the diesel engine air fi lters
as required. Note that the diesel air fi lter can not be
cleaned so scrap it and replace according to maintenance
schedules. See your nearest Regal yacht dealer for fi lter
parts.
Also, it is recommended that aft er a cruise you let the
engines and generator idle under a ‘no load’ condition for
several minutes. Perform a visual check for exhaust and
fl uid leaks in the bilge. Since there is a light gelcoat color
in the bilge bottom it will be easier to spot any fl uid leaks.
Note: Never modify or obstruct any part of the natural
or if installed power ventilation systems.
