S!

Nice pics. I would agree that the exhaust flames are more or less visible mostly at low light conditions, not in broad daylight so clearly, if at all. The DB-engines had direct fuel injection so you really could not adjust the mixture on it. Only adjustable was propellor in case of the automatic failed. Early Bf109's had manual pitch, E-4 and onwards had the automatic with manual as backup(rocker switch on throttle).

Sure the Spitfire or Hurricane is louder as you sit behind the exhaust stacks. In Bf109 they are way lower thus a bit less noise. The Bf110 looks gorgeous, can't wait to fly her! The handling qualities of the Bf109 on the other hand are partially a myth and partially true. If the pilot knows what he is doing it is not any harder to land or take-off in it. Any plane of that era with the big engines were a handful to handle

Have a nice weekend!

Just about OT
Pretty 'Flamey', probably not a good reference.
I love the smell of 5 star in the morning, just not on my meat.

If I am right:
I am guessing that the readouts shown are selectable to some extent. IE. you can pick what you want the read out to be.

I wonder if the number of readouts will be limited to three at a time.

If "comp" is manifold pressure, this points once again to truly complex engine management!

Since there is no value for "comp" in the picture, I am wondering what units will be used (or will it be some sort of percentage based on throttle and mix?).

OR....maybe I am wrong about what "comp" in the picture actually stands for.

Exhaust Flames: I think every other person on this board cares more about it than I do lol. They look good and I sort of look forward to trying to use the colors to figure out just how my engine is running.

My first guess was compression (maybe something to do with different engine types and program modeling processes inside it) - but then again, we won't know for sure until Oleg tells us.

COMP - if MP is for Manifold Pressure, what does CO stand for?

I hardly believe that pilots could manipulate Manifold vacuum (or engine vacuum) other by different throttle settings.

I dont understand why soo much wondering about exsaust...

Once I drived my litle Fiat 126 to repair, without exaust and with last seat bank cuted out, so workman can repair it without bringing engine out of car. (engine is back).

Whan I started it, imagine the noise inside car , it wos nice ,
but whan I started to ride and give more power-15-30 cm flames came out from engine, I wos afraid to fire up car

So why wondering to se flames? Engine is explosion device, will you see it depends on 100 other things, I believe Oleg & Team will make it good as possible!

Also, we need some new kids who will buy this sim and play it as a game, some extra flame highlights are for sure welcome...

In the first three pics of the Hurrican you get a better idea of what is happening if you click next in quick succession so you get a fast slide show. You can see the engine is way over rich, perhaps with the throttle closed and as the throttle is opened the incorrectly burning gas is blown away and turns blue. Try it.
On a slightly different tack I think the landscape is looking excellent with field sizes and shapes and crop textures looking very 1940ish. No houses sitting in fields either and who can complain about colours?
Brilliant Oleg.

Explosion = Knock (detonacije na Hrvatski) which seriously damages the engine (piston heads, piston gaskets, valves etc.). Higher the Octane rating, less chance for engine knocking.

So no, engine is not an explosion device. Judging on how your exhaust flames look you can adjust your mixture (especially important with altitude, as you climb higher). And the most important part (which will drastically change dogfighting as others already stated) are puffs of smoke accompanied with throttle changes.

IL2 already had simplified effect caused by this. Thus, since SoW represents the way forward - it is logical to presume we will have much more detailed engine physics modeled.

[Freycinet]

Thor, in many languages, "explosion engine" is a slightly old-fashioned way of saying internal cumbustion engine, that - I'm sure - is what Adriatic is saying.

[T}{OR]

I admit, I never heard of this expression. Adriatic and I are both from the same country - and I do not know of such (or equivalent to it) expression in my language.

Even so, the fuel inside an engine does not explode. And this is what I was trying to explain. Fuel burning inside a cylinder is a complex process determined by many factors such as cylinder/piston head shape, compression ratio (volume between top of the cylinder to TDC, and top of the cylinder to BDC), number of strokes (2T/4T), position and number of valves (or valves and fuel injectors), intake and exhaust manifold, RPM, fuel - and many many other factors...


EDIT: Call it a professional defect, but I had to reply.

I thought this was already confirmed somewhere?

Some people complain about the visibility of the flames, but there aren't any flames visible from the second Bf 110 in picture 10.

Are those flames only visible from very close in daylight?
