Abstract
Fuel injection control apparatus for direct injection type internal combustion engine controls timing of end of fuel injection so as to be capable of controlling fuel injection volume precisely without raising fuel pressure. The apparatus comprises crank angle sensor detecting rotational angle of internal combustion engine, fuel injection valve directly injecting fuel to combustion chamber, fuel pump supplying fuel to said fuel injection valve whereby supply pressure of fuel is set equal to or less than the maximum cylinder pressure during motoring of internal combustion engine and control means for controlling open or close timing of said fuel injection valve to control fuel injection amount and fuel injection duration and judging timing of closing of the intake valve of inner combustion engine from the rotational angle output of crank angle sensor and controlling fuel injection timing to close fuel injection valve not later than the closing of intake valve
