Another thing to consider is that in early Bible times a name signified something important about you, so it was necessary to change ones name sometimes, to a more fitting one, hence Abram to Abraham, Jacob to Israel etc.
So, what is more important about a person is their reputation, so Jesus having made God's name known need never have required his uttering what we in English would consider a personal name, it would be Jesus great teaching about God being a God of love, his reputation, that Jesus made known.
I doubt whether Jesus, if he came across the Tetragrammaton in a text he was reading would utter anything apart from a substitute, such as Adonai, it would more than likely have caused a riot had he uttered the ineffable Name that only the High Priest knew the pronunciation of.
