PURPOSE:To suppress generation of a smoke in the captioned method for a Diesel engine with a supercharger, by using a maximum fuel injection quantity at intake pressure almost equal to the atmospheric pressure and maximum fuel injection quantity at various intake pressure or the like and controlling an injection quantity. CONSTITUTION:A fuel injection pump 1 distributively supplies fuel compressed by reciprocating motion of a pump plunger 15 to each nozzle 2, and its injection quantity is adjusted correspondingly to the position of a spill ring 21 driven by a solenoid 22. Here on the basis of each output of an engine speed and accelerator opening by each sensor 20, 9, an optimum injection quantity Qb and maximum fuel injection quantity Qf are obtained respectively by an ECU3 and engine speed. While a maximum injection quantity Qf' at then intake pressure is obtained, and a value of K2=Qf'/Qf is obtained. Further a maximum value K2max of the K2 for setting a value Af' for temperature in each part not to exceed a preset value is obtained to control the injection quantity in accordance with a compared result of the K2 with the K2max. |
