ABSTRACT:
In one aspect of the present invention, fuel is injected through the injector into the internal combustion engine in non-synchronism with a predetermined crank angle or a predetermined ignition timing each time when the intake air pipe pressure traverses a predetermined set value from the smaller value side to the larger value side. In another aspect of the present invention, the fuel injection is effected in non-synchronism with the predetermined crank angle or the predetermined ignition timing when the intake air pipe pressure traverses a second predetermined value which is selected among a plurality of predetermined set values (the second predetermined value being larger in the absolute value than a first set value, and being close to the first set value) in a case that a time of traversing the first and second set values of the intake air pipe pressure is shorter than a predetermined time.
