  • Fuel injection timing control apparatus for a fuel injection pump and control method for the same
    Patent number: 5697347
    Abstract: A target fuel injection timing of the fuel injection pump is calculated based on the operating conditions of a diesel engine (Steps 102; 302; 602), while an actual fuel injection timing is calculated based on crank angle signals (Steps 103; 303: 603). Then, a fuel injection timing error (Terr) is obtained based on a difference between the target fuel injection timing and the actual fuel injection timing (Steps 104; 304; 604). To adjust the actual fuel injection timing based on the error (Terr), a rotational position of a roller ring (10) is controlled through a timer piston (21) slidable and housed in a timer device (28) by a hydraulic pressure control valve (27) in response to a pulse actuating signal having a controllable duty ratio (DFIN).
