PURPOSE:To simplify the electronic circuitry thus to reduce the cost and to improve the reliability by providing a register for storing the count of a timer counter everytime when TDC signal is produced and an output port for energizing an injector. CONSTITUTION:Everytime when TDC signal is produced, CPU20 will store the count TpO of a timer counter 71 into #1 register 72. Count Tp1 of said counter 71 corresponding with the time when producing TDC signal immediately before is stored in #2 register 73. CPU20 will apply temperature correction and acceleration/deceleration correction onto the basic fuel injection time Ti to operate the actual fuel injection time signal Ta. Pulses are fed alternatively from the output port 37 to #1 and #2 output terminals p1, p2 thus to energize the injectors 51, 52. Consequently, the electronic control circuit can be simplified resulting in cost reduction and the improvement of reliability. |
