ABSTRACT:
An object of the present invention is to positively feed a necessary amount OF fuel to each cylinder in starting an internal combustion engine and to enhance the startability of the internal combustion engine and the ignitability within each cylinder. In order to attain this object, according to the present invention, a start timing fuel injection controlling apparatus is an apparatus for controlling a fuel injection in starting an internal combustion engine having a plurality of cylinders and is provided with an intake non-synchronous injection means for performing fuel injection out of synchronism with a valve opening of an intake valve predetermined times for each cylinder, and an intake synchronous injection means for performing fuel injection in synchronism with the valve opening of the intake valve for each cylinder after the intake non-synchronous injection means has performed the intake non-synchronous injection for each cylinder the predetermined times.
