ABSTRACT:
A cylinder injection fuel control device for an internal-combustion engine provides a proper amount of fuel at the time of transient operation by reflecting the most up-to-date operational state in control. The cylinder injection fuel control device has a fuel injection valve for directly injecting fuel into each cylinder of an internal-combustion engine and it supplies the amount of fuel required for a single stroke of each cylinder by applying, to each fuel injection valve, an injection signal of a pulse width corresponding to the driving time of each fuel injection valve; wherein the injection signal applied in a single stroke of each cylinder is divided into three pulses, and the amount of fuel required for a single stroke is divided into three portions. A first injection signal and a second injection signal are respectively applied during a suction stroke, and a third injection signal is applies during a compression stroke to the fuel injection valve of each cylinder, and the amount of fuel supplied in response to the second injection signal is corrected in accordance with the operational state of the internal-combustion engine.
