Fuel by itself is of no use whatsoever it needs
oxygen from the air outside in order to burn. At
the most basic level, this happens its own
accord as the piston falls during the induction
stroke, air rushes in past the open inlet valve
to fill the expanding space. Then, when the
compression and power strokes are complete, the
exhaust valve opens and the rising piston pushes
the exhaust gas out ready for a fresh charge of
clean air. In practice, though, the engine needs
an air filter to stop dirt, moisture and bits of
rubbish being sucked into its cylinders, and
needs an exhaust system to dispose of the hot
exhaust gases safely and quietly. To save
having a separate filter and exhaust pipe for
each cylinder of a multi-cylinder engine the
incoming air is fed to the cylinders through
tubular structures called inlet manifolds, and
the exhaust gases are carried away through
similar structures called the exhaust manifolds.
One of the popular is the Mercruiser Exhaust
Manifolds. Air filters Marine diesels usually
operate in a relatively clean environment
there's little danger of them having to contend
with straw, dust or roadside litter. This means
that their air filters can be relatively simple,
so some engines operate perfectly well for years
with little more than a metal box with a few
baffles in it. Most, however, have something a
little more sophisticated, involving either wire
gauze or porous paper. Paper tends to restrict
the air flow, so to make up for this its area has
to be increased by being folded into a concertina
shape. It's also difficult to clean, so once a
paper filter becomes clogged it has to be
replaced with a new one.

Exhaust systems When it comes to exhaust
systems, the boot is on the other foot road
vehicles and agricultural machinery have an easy
time of it. Sometimes even multiple coolers are
used for faster cooling of the heated oil. Their
engines are in compartments that are open to the
atmosphere but sealed away from their drivers and
passengers, so all that's required is a pipe
connected to the exhaust manifold, with a few
baffles to reduce the noise. A few marine
installations adopt a similar 'dry' exhaust
system, known as Omc Exhaust Manifolds usually
in the form of an exhaust pipe sticking straight
up from the engine compartment, with a weighted
flap to stop rain or spray running down inside
and heat resistant lagging to minimize the risk
of fire or burns. The vital thing about any
exhaust system that it must not restrict the flow
of exhaust gases beyond a certain limit, because
if exhaust can't get out of the cylinders, there
will be no room for fresh air to get in. The
effect is exactly the same as if the air filter
were clogged starved of oxygen, the engine will
not be able to burn its fuel, so it will lose
power and produce black smoke. So you should
wisely choose exhaust manifolds for better of the
combustion from marine vehicles.
