INJECTOR CONTROL METHOD FOR GDI ENGINE THROUGH TEST DRIVE

摘要

One aspect of the present invention relates to a method of controlling an injector of a GDI engine through test drive. More particularly, the present invention relates to a method of converting a target fuel amount of an injector into an opening duration and controlling a driving signal of an injector using the opening duration. According to an embodiment of the present invention, when a GDI engine maintains a low-pressure mode in which only a low-pressure pump is driven in an ignition-on-state before engine start, the drive of an injector is tested using only battery voltage to provide a method of training opening duration of the injector.;COPYRIGHT KIPO 2017
