Airbus uses a different (and more useful, in my opinion) method from Boeing, whereby the middle number of the series number represents the engine manufacturer, and the last number represents any special engine variant, etc. For example, take an A330-201 (QF). The middle zero tells us that it has GE
's, and the one just stands for whatever particular special variant the engine might be. The following is a list of the most common middle numbers and their manufacturer equivalant (sorry, I don't have the code for Engine Alliance):
0 = GE
1 = CFM
2 = PW
3 = IAE
4 = RR
I got that info from an extremely helpful and friendly Airbus customer service person, via email...
