Abstract: A method of determining a learning area of injector opening duration according to the present exemplary embodiment divides an entire control area for controlling opening duration of an injector into a learning map area which needs learning and a reference map area which uses an already prepared reference map as is without learning, and a period from a minimum injection time to a minimum linear injection time of the injector is determined as the learning map area, and a period from the minimum linear injection time to a maximum injection time is determined as the reference map area.
