So WS-18 is a copy of D-30KP2. But i was refering to WS-20. It now has been flight tested since 2014 i think, and it appears that it still hasnt met testing requirements. When will it enter service?

I think we shall keep open as to whether the new engine concerned is WS-18 or WS-20 as there is no mentioned of engine designation in the news article. Time will tell, we just have to wait for photo to appear later this year.
The key word from the article is "to prepare for delivery of the first unit of the new engine".
So is the WS-20 final engine for the Y-20?
We have seen the information that it has been in testing for such a long time, how much longer it will take? I think 2020 and the coming years is the time it should appear in service.
WS-20 is likely the final engine for the Y-20. When it will enter service? Nobody really knows at this point, hopefully 2020. We will know when pictures leak of Y-20's testing with 4 WS-20s, signalling it is close to completion.

It does not really matter because what count is WS 18 analog to DK 30 and they will be mass produced soon! China has not sign contract for more DK 30 and with production of Y 20 come full tilt they soon run out of imported engine.
WS 20 is nice to have but not necessary.They can switched over when it is available
I've come around to this way of thinking myself. I used to be amped up and impatient to see the new engines (WS-15, WS-19, WS-20, etc.), but it's much more important to establish robust quality control processes. I don't want these engines to have 1/4 the lifespan of their Western counterparts or, heaven forbid with something like the CJ-1000, fall out of the sky.
