デイーゼルエンジンの燃料噴射制御装置。 It has a rotor that is rotatably supported in a case and has a large number of partition walls forming a large number of cells, and connects the exhaust passage and intake passage of the engine through the cells of the rotor to reduce the pressure in the exhaust passage. This is a fuel injection control device attached to a diesel engine equipped with a pressure wave supercharger that performs supercharging by applying fuel to the intake air, and advances the basic fuel injection timing in accordance with an increase in engine rotational speed. A basic fuel injection timing means and a load-adaptive advance angle correction means for retarding the fuel injection timing from the basic fuel injection timing when the engine load is low and making the amount of retardation smaller when the engine speed is low than when the engine is high speed. A diesel engine fuel injection control device characterized by:
