PURPOSE:To aim at improvements in drivability in time of open-loop control, by installing a device which compensates a control signal to be emitted out of an open-loop controlling device on the basis of engine load to be detected by an engine running state detecting device. CONSTITUTION:A closed-loop controlling device, controlling an air-fuel ratio for feedback on the basis of an output signal out of an oxygen sensor, and an open-loop controlling device, securing the air-fuel ratio to the specified value, both are installed. In time of the open-loop control, there is provided with a device which adds compensation to a control signal to be emitted out of the open-loop controlling device on the basis of engine load to be detected by an engine running state detecting device. Thus, improvements in drivability in time of open-loop control is promoted. |
