PURPOSE:To prevent double or no injection of fuel by means of a fuel injection controller which is used in an internal-combustion engine by making one injection for every cylinder immediately after starting of actuation of a starter switch and then prohibiting injection during one turn of the engine. CONSTITUTION:After a start instruction is inputted, an initial data value 4 or a data value of the second TDC synchronous signal which is smaller by one than the precedent output value is sent to a decoder 522. The decoder 522 generates an output O until each one of all cylinders completes one each suction stroke. Thereafter, the output of the decoder 522 is turned to 1 until a start signal is newly inputted in response to an ON signal of a starter switch. Fuel is supplied only once for all cylinders at the same time by an initial asynchronous pulse CP generated immediately after the starter switch is turned on. Thereafter, injection is prohibited by the output of the decoder 522 until every cylinder completes one each suction stroke. This may prevent malfunction. |
