Abstract
Ignition timing is controlled to provide a fixed advanced timing based on a standard angle signal derived from a standard angle sensor during low engine running speeds such as starting and idling engine timing advance is varied during higher running speeds based on a time duration elapsing from the timing of the standard angle signal derived from the sensor thereby, engine starting performance and idling stability are substantially improved.
