PURPOSE:To perform fine compensation and improve accelerating performance in such a way that in the structure which compensates fuel injection rate in response to the engine condition, accelerating incremental compensation factor at that time of warming up is gradually increased in proportion to the accelerating condition which has been discriminated at the intervals of generating its accelerating signals. CONSTITUTION:During ordinary operation, an electronic control circuit 38 computes the reference injection time Tp through each output from an air-flow meter 12 and a distributor 14, and further the effective synchronous injection time GAMMA1 is computed by compensating said time Tp in response to signals from other various sensor 16, 22, etc. Besides, injection valves 36 are controlled by computing their synchronous injection tiem GAMMAs in such a way that their unavailable injection time GAMMAv which is to be found out when dropping the battery voltage is added to said time GAMMA1. Hereat, the control circuit 38 is formed also for the purpose that when performing the accelerating incremental compensation at the time of warming up, speed in the acceleration is discriminated by means of intervals for generating the accelerating signals, and the accelerating incermental compensation factor at the time of warming up can be gradually increased in proportion to its discrimination results. |
