ABSTRACT:
A fuel injection control system is provided for use in a cylinder injection/spark ignition type internal combustion engine in which fuel is injected directly into cylinders through respective fuel injection valves mounted in the cylinder heads. An ECU determines a desired fuel injection amount based upon the engine rotational speed and an engine load condition, determines desired fuel pressure to be supplied to the fuel injection valves and controls the actual fuel supply pressure relative to the desired fuel pressure. The ECU causes fuel to be supplied under the desired fuel pressure to each of the fuel injection valves, based upon the engine rotational speed and injected thereby into the corresponding cylinder when the crank angle of the engine falls within a predetermined range in the vicinity of a top dead point of the cylinder corresponding to a compression stroke thereof. The predetermined crank angle range is set to a range of 20.degree. BTDC to 5.degree. ATDC.
