PURPOSE:To aim at energy-saving and low pollution control, by carrying out control of the injection quantity of fuel on the basis of fuel injection pressure, while causing the engine speed to follow the command engine speed. CONSTITUTION:Difference between the engine speed information from a tacho- meter TG and command engine speed information N is detected by a speed difference detection mechanism 22 and with which speed difference information DELTAN is outputted. A pressure adjust controller 24 outputs the injection pressure correcting control value to a hydraulic controller 25. An injection nozzle NZ injects the prescribed pressure value, that is, the desired fuel quantity and controls engine speed EN in a pertinent manner. Like this, aiming at energy-saving and low pollution control, fuel injection pressure and timing can be varied over a multifarious range. |
