Abstract
A fuel injection control system may include a variable exhaust valve mechanism configured to primarily open an exhaust valve directly before an intake stroke in which an intake valve is opened and to secondarily open the exhaust valve during the intake stroke such that valve overlap occurs; an exhaust injector provided at an exhaust side to inject fuel; and a controller for controlling the exhaust injector such that fuel is injected through the exhaust injector before the exhaust valve is opened secondarily before or during the intake stroke.
