Abstract
A calculation control circuit unitA is provided with a microprocessor, an auxiliary control circuit unitA, and a high-speed A/D converterto which the detection signals of excitation currents for electromagnetic coilsthroughare inputted; based on an valve-opening command signal generated by the microprocessorand excitation-current setting information, the auxiliary control circuit unitA opening/closing-controls power supply control opening/closing devices by use of a numeral value comparator and a dedicated circuit unit, and monitors and stores at least one of the peak value of a rapid excitation current and a peak current reaching time; the microprocessorperforms correction control with reference to the monitoring storage data, and implements fuel injection control while reducing a rapid control load on the microprocessor
