<p>A fuel injection control apparatus of a diesel engine includes a spill valve (126) which opens and closes a high-pressure chamber of a fuel injection pump. A rotation angle sensing unit (106) senses a rotation angle of a crankshaft of the engine. A first unit (12, 442) sets the spill valve in a closed condition each time the rotation angle sensed by the rotation angle sensing unit is equal to a spill-control-off rotation angle. A second unit (12, 400, 410) sets the spill valve in an opened condition when the rotation angle sensed by the rotation angle sensing unit is equal to a fuel-injection-end rotation angle. A third unit (12, 408) inhibits the setting of the spill valve in the opened condition by the second unit when an engine speed during a cranking condition of the engine is less than a reference value. A fourth unit (12, 432, 434) inhibits the setting of the spill valve in the closed condition by the first unit during a period from the start of cranking of the engine to the start of computation of the engine speed. <IMAGE></p> |
