No madness, just method!
The first digit (e.g. (-2xx) denotes the series
The second digit (e.g. -x4x) denotes the engine manufacturer (GE=0, CFM=1, PW=2, IAE=3, RR=4 - please correct me, if I am wrong with the allocation)
The third digit (e.g. -xx1) is - bluntly speaking - the version of the respective series.
X denotes upgrades MTOW etc.
LH operates some A320-211. These are early-model -200 series with CFM56 engines.
Condor operates A320-214. These are later model -200 also with CFM engines.
An A330-343X is a RR-powered -300 series A330 with an increased MTOW and some refinements over earlier -341 or -342 series aircraft.
Hope this helps and I didn't get too much wrong.
