Abstract

PURPOSE: To facilitate the control of a fuel injection in an electronic fuel injection device for a diesel engine by accumulating high pressure fuel from a piston pump controlled under injection pressure in response to the engine rotation in an acccumulator and then supplying the fuel to respective injectors via rotary valves suitably controlled.
CONSTITUTION: The input shaft 20a of a piston pump 20 is connected to the output shaft 1a of an engine 1, and the predetermined high pressure fuel is fed under pressure to a fuel accumulator 26 via check valves 22W25 at a timing meeting to the engine rotating speed by the pump 20. The fuel pressure in the accumulator 26 is detected by a pressure detector 27, a control rack 21 is controlled by an injection pressure controller 30 in response to the output of the detector 27 and the output of a position detector 36, thereby maintaining the pressure of the accumulator 26 to set pressure. The high pressure fuel in the accumulator 26 is fed to the respective injectors 10W13 at the predetermined fuel injection amount and timing via a rotary valve 40 controlled by the signals V1, V2 or the like from a rotary valve controller 80.
