I wonder if the proper firing order has been simulated as well? Judging by the amount of details already shown, I would be surprised if it wasn't.

rumor is that game ships with a timing light and cloth map

Ah, I thought we were comparing WW2 carbs with WW2 mechanical injection. Because the Pierburg would probably have a hard time compared with Bosch Motronic, itself already 25 years old. K-Jetronic is very simple indeed.

What Richie said just doesn't make sense: engines won't produce different flames if they're direct injected or carburator injected. Or maybe I got it wrong in the first place.

I don't really explain things very well. I think that fuel injection is a much more precise system than a carbureted engine and much less likely to flame up when being started. In all of the videos I've watched of 109s being started not once have I seen one have a stack fire. That's why I said I thought the Allied pilots will have more fun with the flames and over priming than the Germans will. Does that make sense? Put BF 109 in youtube and watch 109s start.

Did you forget that Oleg himself requested the community to talk about this subject? Post like yours is the useless ones.

Well it really doesn't really matter if we go over board because he can pick and chose what information he can use and what he likes right?

Hopefully we get some nice christmas special friday update with release date, publisher name, awesome effects video and more.
I can't wait.

..The truth is that I like physics but I've always been rubbish in maths (I always lose a + or a - somewhere..).. LOL

Never been into an aero engine, but I work on lots of old stuff. Everything from a Model T Ford to E-type Jaguars and a Lotus 11 LeMans.

Actually, driving the very early cars has much in common with early aircraft. The carbs are very rudimentary, as are all the other systems. They require constant input from the operator to be at their peak. Every gross change in throttle setting demands a change in mixture and spark advance, and it all changes as the engine warms. The settings you left the shop with will not be the settings you come back with.

It's a type of driving I really enjoy as it requires actual thought and input.

These are my thoughts as a steel fabricator. Using an oxygen acetylene cutting torch as an example... A very rich mixture of gasses coming out of the torch is Orange with much Black smoke. A high oxygen mixture is Blue White.Setting the mixture At the optimal point between an Oxidising flame and Carburizing flame is ideal.

I believe that effciency in an engine may be measured thus, and exhaust coulor be matched accordingly.

Thankyou for your patience

The point is.. Is it running Lean or Rich?

[WTE_Galway]

Carby mixture settings have nothing to do with the stack flames on startup.

Carburetor aircraft engines commonly have a hand priming pump like the one below out of a spitfire:



The pump injects fuel directly into the carb barrel or intake manifolds. Pumping it too many times before cranking the engine results in an excess of fuel and exhaust stack flames can result.

Right. If you look at all of the engines in the videos...in they dark... they're all blue. By the chart that was put up if the mixture is right and the engine is running perfectly the flame should be blue with a lick of red at the end. If you stood right up close maybe you could see some red.
