I-16 neg-g carburator?

[Anaxogoras]

I just noticed that our I-16's engine does not cut out in neg-g maneuvers, but in Il-2 it does.  Anyone know which is correct?

Yes.

Is my question not clear?  In the flight sim Il-2, the I-16's engine cuts out when you nose over and sustain negative g's, just like the Hurricane and Spitfire Mk I.  Our I-16, the Aces High I-16, sustains power through negative g maneuvers.

The Shvetsov ASh-62 or M-62 engine used in the Polikarpov I-16, while being a nine cylinder Radial, is carbureted.   I said the same thing to myself last night in my Candy Mountain Mishun over TT.

I have no idea but, Carbureted on a radial would act different than carbureted on a V, wouldn't it?  The radial having cylinders all around 180^o, on the bottom, sides, as well as on top?

Just an observation.

Well not all carby's of that era had the neg G stall problem... Americans were useing an updraft, 3 ventury, pressurized carburetor, on radials well before the war...
Whether the Russians had the same thing or not, I don't know... Another thing to ponder, is that American radial engine tech was much copied around the world at the time...
Some engines were built under license, by Rhone, and BMW, other designs were just plain stolen...
Actually with a pressurized carb, you could mount it any way you want, up, down, or side draft...

Like RipCord said, most aircraft in AH use carburators. It's the architecture used that makes the difference. The Shvetsov 1100hp M-63 we have in AH's I-16 is derived from a license-built Wright Cyclone. None of the Cyclone engined aircraft in AH have this problem either. On top of my head, the only fighters with fuel injection in AH are 109s, 110s, 190s, La-5fN/7 and KI-84.

I forgot the N1K2 from the fighters that use fuel injection.

Ya I love it when I hear"only the spit 1 has a carb,the rest are fuel injected"

 I guess a bendix injected carb is some kinda fuel injection......

Yes, that is a big misconception, isn't it.  From the reading I've done, the main benefit of fuel injection was throttle response...  But now back to the original question.  Anyone know about the I-16?

Wait.... I missed a Candy Mountain Mishun?!?!?

Apparently the M25 used a K25 solex carb and was a direct copy of the wright cyclone R1820-F3

 which is in several US navy birds and those dont suffer from neg G fuel issues.

So I wasnt able to find out about the K25 carb but I'd bet HTC has it modeled correct.

#1 All Carbs are not created equal.

#2 Some carbs used a float to control the level of fuel entering.
Said float under neg gee's would cut off the fuel entering the carb, from where it goes through jets, valves, etc for establishing a fuel air mix, which is then pulled into the Intake manifold.

#2 other cards control fuel level differently, and would not be effected by Neg Gee's.

Only Carbs with a float would experience Neg Gee cutout as the early Hurri & spit do.
