Disclosed is an injector injection nozzle opening timing detection apparatus. The injector injection nozzle opening timing detection apparatus of the present invention comprises: an injector control unit which applies an electrical energy to an injector so that an injector injection nozzle injects a fuel by a preset fuel injection amount; a motor rotation speed change amount detection unit which detects a motor rotation speed change amount caused by a change in an engine torque due to the electrical energy; and a learning unit which learns the opening timing of the injector injection nozzle based on the motor rotation speed change amount. Provided are the injector injection nozzle opening timing detection apparatus, which detects the opening timing of the injector based on the motor rotation speed change amount, and a method thereof.
