A fuel injection control device for an engine comprises a fuel injecting device for directly injecting fuel into a cylinder of the engine and being capable of changing fuel injection rate arbitrarily during injecting the fuel, a fuel supplying device for supplying high-pressure fuel to the fuel injecting device, and a control unit for controlling the fuel injecting device depending on an operating region of the engine so as to adjust a quantity of fuel to be injected into the cylinder of the engine, the control means reducing the fuel injection rate of the fuel injecting device once and subsequently increasing the fuel injection rate during the main injection that contributes to torque generation of the engine. |
