PURPOSE:To detect the injection amount of fuel with high acuracy by reading out the injection amount of fuel from a data map stored in ROM on the basis of the average torque and the number of revolutions obtained by computation. CONSTITUTION:A torque sensor 22 is arranged on a main shaft 21 of a fuel injection pump 4, while an electromagnetic pickup type revolution number sensor 23 is arranged at the rotational part inside the pump 4. The signal of the torque sensor 22 is integrated in a computation circuit 24 to obtain an average torque, and the signal of the revolution number sensor 23 is outputted to a computation circuit 25 to obtain the number of revolutions. In a computation circuit 26 composed of MPU, an injection amount of fuel QS is obtained from a data map previously stored in ROM on the basis of the above said average torque and number of revolutions. The fuel injection amount QS thus obtained is used, for example, as a governor controlling feedback signal and the like in an electronic control type fuel injection device. |
