(57) In an engine including a passage injector (6) and an in-cylinder injector (7) that
allocates and injects fuel, a fuel injection controller prevents the fuel injection
amount of each injector from falling below an allowable lower limit value (min1, min2).
When the fuel injection amount of one of the passage injector and the in-cylinder
injector becomes less than or equal to a value (A, B) indicating the possibility of
the fuel injection amount falling to less than an allowable lower limit value due
to correction with a correction value (FAF, FAF1, FAF2), the fuel injection amount
of only the other one of the passage injector and the in-cylinder injector is corrected
with the correction value.
