PURPOSE:To neglect an asynchronous injection pulse and normally generate a basic injection pulse when timing pulses of synchronous and asynchronous injection are overlapped, in a fuel injection device which performs fuel injection by an asynchronous injection pulse at acceleration time. CONSTITUTION:An acceleration signal C2 is input from an acceleration detector 7. An acceleration excess calculated value is loaded to and counted down by the second down counter 57A4 with a trigger signal D4, and if zero is counted, a carry signal D6 is generated. Accordingly, a signal D5 becomes an asynchronous injection pulse for an acceleration excess. A synchronous injection pulse D3 for basic injection is obtained by the first down counter 57A1. When the synchronous injection pulse D3 and the asynchronous injection pulse D7 are overlapped in their timing, a load signal of the signal D5 is not generated by an AND circuit, then the asynchronous injection pulse is neglected. In this way, a basic injection pulse is normally generated. |
