Abstract:
A fuel injection control system for a diesel engine, comprising:a fuel injector for directly spraying fuel into a combustion chamber in a cylinder of the engine; a split injection controller for controlling the fuel injector to perform a primary injection of fuel at least at a point of time near top dead center of a compression stroke of the cylinder at a plurality of split injections, one split injection being followed by the next split injection after an injection intermission interval which is a period lasting until the fuel injector is opened next following closing thereof; a judger for judging that a completion timing of the final split injection of the primary injection is later than a point of time corresponding to a specified crank angle; and a corrector for correcting at least one of the number of split injections performed as the primary injection, the injection intermission interval and a fuel injection pressure so as to advance the injection completion timing when the judger judges that the primary injection completion timing is later than the point of time corresponding to the specified crank angle.
