Abstract:
A fuel injection control device for an in-cylinder injection internal combustion engine, comprising:a processor that selects one of a compression stroke injection mode in which fuel injection is conducted during a compression stroke, and a suction stroke injection mode in which fuel injection is conducted during a suction stroke, depending upon operating conditions of the engine;an engine deceleration degree detector that detects a degree of deceleration of the engine; anda fuel cutoff control switch that controls a fuel supply to a combustion chamber of the engine based on whether the operating conditions of the engine establish a fuel cut condition, the fuel cutoff control switch cutting off the fuel supply when the fuel cut condition is established and resuming the fuel supply when the a predetermined fuel cut return condition is established,wherein the fuel cutoff control switch resumes the fuel supply during the suction stroke injection mode when the degree of deceleration of the engine detected by said engine deceleration degree detector satisfies a predetermined condition.
