Abstract:
A starting fuel injection control device for an internal combustion engine, comprising:a starting ability estimating unit for estimating the starting ability of said internal combustion engine; a crank angle detecting unit for outputting a crank angle signal in synchronization with a specific crank angle position of each cylinder of said internal combustion engine; a cylinder discriminating unit for discriminating a reference crank angle of a specific cylinder, hereafter referred to as cylinder discrimination; a first injection unit for simultaneously injecting fuel to all the cylinders before completion of said cylinder discrimination at the starting time; a second injection unit for starting independent injection by turns for each cylinder in synchronization with said crank angle signal just after completion of said cylinder discrimination; and a stopping period determining unit for determining whether a predetermined time period has lapsed before said cylinder discrimination has finished, further comprising a simultaneous injection stopping unit for stopping said simultaneous injection until completion of said cylinder discrimination, only in the case where starting ability of said internal combustion engine is estimated to be better than a specified level.
