engine from inside the cabin is very common to clean the

<br>
</font>It also remove the little leaks from the exhaust and the oil
dust. And works very well on the surface. <br>
In Euronaut the diesel air inlet is from the battery bilge compartment
to vent also the battery gases during charing them on the surface run.
<br>
<br>
The problem in real is more : If you stop the diesel for diving and
close the hatch to dive and run electric. <br>
<br>
The inside goes pretty hot and dusty because you have some big
block of hot metal (engine, gear , compressor etc) <br>
in you engine chamber.. Nice here in norther europe during the
winter period.. <br>
Will not imagine what it means in the caribiean during summer. <br>

><span>I would think you will need an ac unit on your engine because
the engine will generate some heat even with a water cooled
manifold. If you run the exhaust stack inside the air stack it
will pre heat the air coming into the engine. Pre heated air is
good in northern latitudes but bad in the tropics. The heated air
will kill your fuel efficiency. I also would not suck the
combustion air through the hull, the exhaust will find its way in.
I would do a short air stack and a tall folding exhaust
stack. <var id="yiv1125570141yui-ie-cursor"></var> A
diesel engine in a psub is a great idea.</span></div>

<div class="yiv1125570141y_msg_container"><br>
I've been following this discussion with great interest. I don't have a
<br clear="none">sub yet, but I do live in the Tropics, and as there's
no cold current <br clear="none">handy to where I live any subbing I do
will be in water pretty near air <br clear="none">temperature. As you
might expect, I've given this problem a lot of thought.<br
clear="none"><br clear="none">My tentative conclusion is that, if I
build a sub, I will have to make <br clear="none">it more autonomous
than is the rule on this list. Specifically, it will <br
clear="none">need a combustion engine to ferry itself on the surface to
dive sites, <br clear="none">and to maintain comfort and keep the
battery topped off for diving while <br clear="none">doing so. I started
with the assumption that I would need an air <br
clear="none">conditioning unit running off a small industrial diesel,
but then I <br clear="none">realized that, if I use a snorkel exhausting
into
the cabin, and have <br clear="none">the diesel draw air from the
cabin, I get continuous renewal of the air <br clear="none">in the cabin
without the cost, power burden and safety problems of <br
clear="none">running a Rankine cycle refrigeration system. That's the
solution that <br clear="none">I've retained for the moment. Of course I
also need a secure means of <br clear="none">preventing exhaust gas from
being aspirated into the snorkel (I can't <br clear="none">quite
understand how naval submarines manage to combine both functions <br
clear="none">in one mast), but that might be as simple as having the
diesel exhaust <br clear="none">flush with the hull, with some
arrangement to prevent water from coming <br clear="none">in. Since the
diesel would only be used on the surface, and the snort <br
clear="none">would only be there to allow a low-freeboard hatch to be
kept closed, <br clear="none">the power penalty would be minimal.<br
clear="none"><br clear="none">Fuel storage,
fuel feed and the like still have to be worked out. Naval <br
clear="none">submarines have very complex arrangements for this, and
that complexity <br clear="none">must be tolerated for a good reason.
Even so, I need a simpler way to do <br clear="none">it that still
protects the fuel from contamination and me from asphyxiation.<br
