ABSTRACT:
An object of the present invention is to provide an intake synchronous injection type fuel injection controlling apparatus in synchronism with an intake stroke in starting an internal combustion engine, which may positively feed necessary fuel for each cylinder and improve startability and emission. Then, according to the present invention, in order to attain this object, there are provided with an injection number counter means for counting a total sum obtained by summing fuel injection numbers of all the cylinders from the start of the internal combustion engine, and a fuel injection timing changing means for advancing a fuel injection start timing by a predetermined period when the fuel injection number counted by this injection number counter means is equal to or more than a predetermined number.
