Abstract

PURPOSE: To control the fuel injection pressure and the fuel injection timing very easily and arbitrarily by controlling the fuel supply to a fuel injection nozzle by means of a hydraulic control valve actuated by an electric command.
CONSTITUTION: When a position detector 11 arranged in the vicinity of a crankshaft of the engine detects that the engine reaches the fuel injection start point, a reference position marker 1 outputs a signal to a high-speed switch SW and a time interval controller 2. A main controller MC provides a fuel injection rate command signal to a converter 22, where the command signal is converted into a signal representing a time interval at which the operation of the high-speed switch SW is connected. The time interval signal is then fed to the high-speed switch SW via a timer 21 which comes into operation after the time interval represented by the time interval signal is elapsed to cause the high-speed switch SW to halt its operation. A solenoid valve 5 of a hydraulic pressure direction control valve 31 is energized by the actuation of the high-speed switch SW to open a valve member 6. Through thus opened valve member 6, a high pressure fuel 7 is supplied to the fuel injection nozzle 8.
