This is the inclusion functor TorsFreeAbAb\TorsFreeAb \hookrightarrow \Ab. It can also be seen as a forgetful functor which forgets the property of being torsion-free. The functor provides a typical example of a fully faithful functor that does not preserve coequalizers and does not preserve epimorphisms.
