PURPOSE:To obtain a good acceleration characteristic, by determining an acceleration fuel amount while applying a rotary speed as the main parameter in the case of a motorcycle engine. CONSTITUTION:Output signals from an engine temperature sensor 24 and an air flow meter 18 are input to an input/output circuit 36 of a control circuit 30 and converted into digital values. Further, an output pulse is input at each 180 deg. turn of a crank angle from a crank angle sensor 22, and a fuel injection pulse controlling an injector 60 is output in accordance with said output pulse. Further outputs of a throttle switch 22 and a starter switch 40 are input as signals of one bit. In accordance with these input signals, a computer 32 outputs both the control signal of a fuel pump to a pump 54 by the execution of a program and the fuel injection pulse to the injector 60 in response to the output pulse of the crank angle sensor. An injector pulse signal (B) is applied to the air flow meter, and an acceleration injection pulse A.TA is generated in accordance with detection of an acceleration condition. |
