Drużkowski maps play a significant role in the study of the Jacobian conjecture. To investigate Drużkowski maps, we identified more Drużkowski matrices via quasi-D-nilpotent matrices, and then studied the corresponding Drużkowski maps. Some necessary and sufficient conditions in which quasi-D-nilpotent matrices were Drużkowski matrices were given. In addition, several classes of special Drużkowski matrices were characterized.
