Abstract
PURPOSE: To enable the improvement in fuel consumption while obtaining exhaust gas performance by controlling the fuel injection timing in the vicinity of the injection timing for producing the maximum torque at low load torque time and delay injection timing as compared with the above injection timing at high load torque time.
CONSTITUTION: In a lead angle setting citcuit 6 which receives a control rack position T of a fuel injection pump and an engine rotating speed N at an ordinalry low speed running time, a switching element 65 is, when the engine torque is the predetermined value, e.g., less than 50%, closed by the output of an element (Schmitt circuit or the like) 63, thereby producing an A characteristic forming circuit 61. In this state, the load will vary and when the rotating speed varies, the set lead angle moves on the A characteristic, and the injection timing regulating mechanism is operated in accordance with the set value θi on the other hand, when the output torque is increased at the accelerating time, the signal of the switching element 66 is outputted as the set lead angle θi.
