IGNITION TIMING CONTROLLER AND CONTROL METHOD FOR INTERNAL COMBUSTION ENGINE

A CPU advances ignition timing within a range in which knocking can be suppressed by feedback control based on an output signal of a knocking sensor. The CPU sets the igniting timing based on a feedback adjustment amount and a learning value. The CPU limits timing advancing update of the learning va...

Beschreibung
Zusammenfassung:	A CPU advances ignition timing within a range in which knocking can be suppressed by feedback control based on an output signal of a knocking sensor. The CPU sets the igniting timing based on a feedback adjustment amount and a learning value. The CPU limits timing advancing update of the learning value when an exhaust pressure is higher than or equal to a threshold.
