Abstract
In a diesel engine equipped with an injector 1 having a plurality of intersections between an axis line of the injector 1 and the axes of injection holes 10a bored in the injector 1, an air intake valve 25 is controlled so that it is closed at timing before a BDC (at timing when a piston comes to a bottom dead center) by an ECU 50, which controls the timing of closing the air intake valve 25 based on operating conditions of the engine.
