Abstract
A fuel injection timing control device includes a lift sensor for detecting a lift amount of a needle valve of a fuel injection nozzle, rectangular wave conversion means for converting an output signal of the lift sensor to a rectangular wave with a predetermined threshold level, and ignition point calculating means for calculating a timing for actual fuel ignition on the basis of the converted rectangular wave in accordance with a driving condition of the internal combustion engine, wherein the fuel injection control is performed on the basis of the calculated ignition timing.
