So does the WS-10 though? Frankly the petals look like neither. It's entirely possible that it's just a re-petaled AL-31, but it's hard to say.

The number of 2nd set petals on the WS-10 engine matches with that of the number of petals on the nozzle. That is clearly not the case for AL-31.
Not even re-petaled. Painted.
Painted... black with serrations? What kind of temperatures would be experienced at that kind of position?
Also, the lines on Al-31's 2nd petals do not quite line up with the nozzle's petals, where as the J-20's engines currently do... I'm not quite going to call it either way, and I am very cautious about determining the type of engine which is being used when the nozzles are clearly different from both WS-10 and Al-31 and any similarities between either could very well be superficial.
Not as high as you would think. The external part of the nozzle don't experience the same kind of temperature as what goes on inside.
Look at it closely AGAIN. It is obvious that the external petals, which are painted black, don't match with the nozzle petals!
As for big shrimps... MAYA is one of the top "engine experts" from FY and CD. He concluded that the engines were AL-31 a few weeks back. He also said the same thing on this forum. Big enough of a shrimp for you?
Well, I do trust maya, and I see what you mean now. However, I don't know if it's painted black so much as there are an external set of black tiles? Anyways, I suppose this isn't too surprising really.
Maya is not correct 100% of the time. Huitong, (another big shrimp) doesn't think they are AL-31.
Looking at the photos, it is really hard to say. I am leaning more towards AL-31 now, but who knows. If I remember correctly, the shot of the inside of the engine didn't match AL-31 though....
I see, well then I have to wonder how and why they both painted over the 2nd petals with serrations, and modified the actual nozzle with serrations. Maybe they changed the entire structure?
As for "black" petals vs the nozzle's petals -- they don't match yes, there is an extra petal/line in the ring of "black" petals like the Al-31, but unlike the Al-31 they seem to line up perfectly.
Concluded... from his own knowledge/eyeballing, or from insider info? If the latter, it would be far more convincing and enough to put doubt into my mind. It'd be nice to get a consensus of credible folks from the chinese boards together to compare notes with one another. Like centrist said, huitong doesn't think it's Al-31 at the moment either but that could be subject to change soon if what maya said propagates into other boards.

Yeah what about the rings on the outside of nozzle? I don't see it on the AL-31.
