Abstract
PURPOSE: To perform an optimum control operation of fuel feed to an engine and prevent a generation of black smoke, by controlling a control rack of the Diesel engine of fuel injection type on the basis of various kinds of temperatures and suction pressure further performing the feed-back operation of position amount of the rack.
CONSTITUTION: A control rack 20 provided in a fuel injection pump 2 of an engine 1 is determined its shifting amount by a fuel injection device 30. The signal of a throttle valve opening degree sensor 6 is corrected by a PID compensation circuit 33. While the signal of a rotational speed sensor 7 is input through a converter 31 and compared with a reference rotational speed by a function generator 32. Further the signal of a suction pressure sensor 8 passes through an upper limit circuit 42. Those of the above signals are input respectively to a minimum signal preference circuit 34. Then a minimum requirement of fuel is fed to the engine suitable for its operation simultaneously with a fed-back signal from a position sensor 10 of the rack to the output signal of said circuit 34, thus to finally perform a correction of the rack 20.
