Do you have a question? There is no /z/ in 'excursion', unless you pronounce it /ɪgˈzkɜː.ʃən / or /egˈzkɜː.ʃən/, as some people do.

Hi teachers.
I've heard z in sion (I've Cambridge dictionary software).
Thank you.

What you heard is not /z/, but a similar sound: /ʒ/, which is a voiced counterpart of /ʃ/.

Hi all teachers,thank you for your help.
Please why it don't write in IPA with /ʃ/,and what is the meaning of a voiced counterpart .
Thank you.

[JohnAnderson]

In North America we pronounce it /əkˈskə˞ʒən/

/ʒ/ is identical to /ʃ/ except that it is voiced. Just like /z/ is identical to /s/ except that it is voiced.

If you are asking why a certain dictionary writes /ʃ/ but has a sound file that says /ʒ/, then it's probably because different people do the voice recordings and the IPA transcription. That doesn't excuse it, but it could explain it.

Hi all teachers ,thank you for your help,so what is the rule to know that you must pronounce /ʒ instead of /ʃ/.

Thank you

There's no rule. If you're American, as JohnAnderson says, you use /ʒ/. If you're a non-American native English speaker you use /ʃ/. If you are neither, you get a choice.
