Is there an exhaust mod?

[GoldenRivet]

I seriously doubt if smoke was a large factor in spotting the U-boats

firstly... the U-boat exhaust smoke is very light even when the engine is turning out a lot of power

secondly, the u-boat has such a low profile in the water you would likley spot another ships smoke LONG before they spotted yours.

Exactly.
If AI was to be a factor, it should only be done
if a damaged engine effect was used.

Then spareingly.

i drive heavy earthmoving diesel machinery for a liveing anything up too 400 tonnes and the only time a diesel will smoke is when you open the throttle there is a cloud of black smoke until it reaches maximum revs then the smoke disappears after about 2 seconds ,diesels are not dirty smelly machine that we have come too believe in fact they are very powerful at low revs they have lots of torque and very fuel efficient for thier size hence ships lorries trains cars .white smoke is unburnt fuel e.g . when starting a worn engine there is a lot of white smoke until engine warms up blue smoke is also a worn enigine that is burning oil i hope this helps and goog luck with the mod "smoke is good people who smoke is bad":rotfl:

when starting a worn engine there is a lot of white smoke until engine warms up blue smoke is also a worn enigine that is burning oil

To be more precise, white smoke means that oil -lube oil- is being burnt together with the main fuel, which in old engines happens as the tolerances of the rods, valves, camshafts and such have decreased and lube oil leaks into the combustion chamber until the engine warms up and goes to normal tolerances. Blue smoke is more an outlet camshaft & valves common problem of old engines, as fuel is thrown out without the complete burn cycle being completed, and heated in the exhaust.

the only time a diesel will smoke is when you open the throttle there is a cloud of black smoke until it reaches maximum revs then the smoke disappears after about 2 seconds

That's correct. Diesels rev up through adding only fuel to the mixture, not fuel+air like petrol engines, thus the more intensive combustion causes thicker smoke.

It doesn't matter that much...at sea, there's nearly always a breeze - or stronger - which will quickly spread the smoke from a relatively small sub-diesel.
Certainly when there are waves, which have an additional disturbing effect on aircurrents at surface-level.

Imagine how an albatros sailes the wind over the waves...smoke from a sub-diesel (emerging at nearly water-level) is more likely to be drawn downwards between two waves...and as soon as it pops over a wave, it's being grabbed by the wind, and dispersed.

In real-life, a watch-crew would probably be earlier alarmed by the smell, then by the sight of diesel-smoke...if the wind is right...and the source is close.

In Buchheim's "Das Boot" the commander uses the smoke at flank speed to cover the boat/its wake when they are operating on a convoy and see an escort at 180°...

This mod looks very promising...
Thanks for your work, Privateer!

In this clip the smoke puffs is briefly visible (1:48) and the boat is probably travelling relatively fast while being escorted out from the port.

Here a photo from my grandfather`s album. A dutch KVII sub.
Normal cruising and no smoke.

Mostly, from what I've seen, my Diesel trucks,
And old video clips and such is this.

We would see more of a heat distorsion with a very light
whiteishy blueishy, tint from the bridge.

A minute amount of poof, if you will,
as we throttle up.

A slightly stronger tint of white at full throttle, but it should not
be over whelming, just a "dash".

Toss in a "pinch,...NO!!..Not THAT BIG!" of blueish-gray,
and we're close.

If I can get it attached to the Telegraph,
make it "Somewhat" player controllerable,
(by includeing a tweak file)

And include a few magic words.

Would we be close?

:rotfl: :rotfl: :rotfl:

PLEASE! All this is ment tounge in cheek!
So take it that way. OK?

:rotfl:

[GoldenRivet]

ok so i think we can all agree on a few key points

1. The U-boats DO produce smoke during periods of high powered acceleration.
2. The U-boats DO NOT produce smoke when at normal cruising RPM
3. This mod would be really cool if only someone could find a way to make the smoke appear BRIEFLY (3 seconds or so) under the following conditions...
A. Any time when starting The U-boat from a dead stop
B. Whenever you are on the surface and select the next
highest speed setting on the telegraph.
C. when ahead flank is selected for crash diving

I think we can all also agree that the smoke should not be too dark or too light in color and should be substantially smaller than a merchant's exhaust.

I think you can tell from the pic I posted it is way smaller.
The new adjustments are lighter, smaller, and nearing the
"heat effect"

BUMP,any news how this is going privateer,cause it looks fantastic

Still going through the Sub stuff trying to tie the smoke to the Telegraph.
If I don't find a way there, I may tie it to the prop wake.
At least that would simulate start and stop of engines.

[nikbear]

Excellent,can't wait cause this will really add to the atmos when out on patrol
