A Kan fibration that at the same time is a weak homotopy equivalence is called an acyclic Kan fibration. (Also a trivial Kan fibration.)
Acyclic Kan fibrations are precisely the morphisms of simplicial sets that have the right lifting property against all simplex boundary inclusions.
They are the acyclic fibrations in the standard model structure on simplicial sets.
