Abstract

PURPOSE: To make variedness of fuel injection rate small by compensating the time range between the start of current supply of electric pulses which are to be impressed upon a coil of an injection valve and the completion of the lifting operation of a needle.
CONSTITUTION: The driving condition of the internal combustion engine 10 detected by the group of sensors 20, and, on the basis of the outputs from the sensor 20, the pulse time range (tp+a') is operated at an injection pulse range operating circuit 30. An injection pulse range correcting circuit 40 operates the time T0 from the beginning to the end of a needle lifting operation to correct the pulse time range (tp+a') to obtain the pulse time range such as ti=(tp+a'+bT0). An electromagnetic injection valve 50 injects fuel of which rate corresponds to the electric pulses of the time range ti.
