摘要:
An electronic air-fuel mixture control system is adapted to an internal combustion engine to determine an optimum air-fuel ratio in dependence upon renewal of a plurality of learning values related to a plurality of load regions of the engine. The control system is arranged to conduct simultaneous learning of the learning values at a frequency in accordance with lapse of time and to conduct selective learning of the learning values in accordance with change of the load acting on the engine.
