Excellent information find!
It shows that all types of fires can be seen depending on what is happening in the engine.

Unfortunately I doubt that the game engine has been programmed with allowance for these variations if Oleg is only just now asking for information on stack-fire types.

Oleg: I hope I am wrong. Am I?

Many engine heads know the exhaust smoke is a good indicator about how the state of an engine is...

If you test run engines in a test bench without the exhaust pipes on the colour of the flames are also a decent way to identify any problems...

My observations of engines i have worked on

idle should be yelow with a blue base

i work with RPM`s not power settings..

at 2800 RPM`s with no load on the engine it should be yelow with a small red base

at 2800 RPM`s with load its a 50/50 yelow and red

at max settings and full work load it should be blue base with red and yelow..

This is what i know from carburator engines...

When a engine works the tempeture will change etc....

Overprimed engines will make a yelow flame, normaly with werry dark grey or black smoke puffs....

But there is more to it.....how well do the oilring scrape the cylinder wall etc....a small ammount of black smoke doing start up can indicate a small ammount of oil left in the cylinder.....thats actualy ok as long it stops when the engine gets to operating tempeture...

Whitesmoke is also ok...again if it stops at operating tempeture

White and blue`ish smoke on startop is a no go....that is both water and oil and thats bad no matter if it stops or not, that is a mixture of oil and water...and that should not happen.....

I personaly dont care about colours, the awsome part for me was the working of each seperate cylinder....that is cool, and that realy give my hope up for the shot up cylinders...German and british plane dont like that, but later on the yanks radials aircooled will love that...we might get the **holy crap i landed on 4 cylinders**

Spits and 109`s wount like loosing cylinders....the 190 will fare abit better on it....man just the ideas about the different things that can go wrong with engine hits....

woooooot!!!

Wow, we can have this stuff already in IL2?!?

Now that would be cool to have mod/developement in 4.10m.

Schhhhhhh

Its the unmentionables

Thanks for the update Oleg, would it be possible next week to show some footage of fully weathered fighters having a dogfight, this would be most pleasing. Many thanks.

Peace to you all this christmas.

Sounds good Tree.

I'm trying to find that aviation artwork of the English boys sitting on a wood fence as they watch a Spitfire coming towards them with it's gear down as it's about to land on the field behind then. I always think to myself I wish I was sitting on that fence.

OOO found it

My question to community: isn't it too yellow? Maybe to add a bit red color in a mix with yellow? It is tunable really, so I would like to listen suggestions

Since you said you have the colors for the other types of flames, i guess we are only talking about the "yellow" flame.
I think would look better in with a more orange tint. That may also make the greenish reflections a bit more "warm".

Thank you for the update.

Fair enough but there really shouldn't be any reflections on the aircraft skin. I've yet to see one piece of evidence showing reflections on the panels of the aircraft from exhaust flames. While it looks nice, that kind of illumination would have been completely unacceptable in wartime, not to mention the effect on pilot vision.
