ENGINE IGNITION TIMING CONTROL DEVICE

Japanese Patent JP2016125476

A

PROBLEM TO BE SOLVED: To restrict vibration of an engine generated by changing an ignition timing map when an intake flow control valve is changed over from a closed valve state to an opened valve state.SOLUTION: An engine ignition timing control device including an intake air flow control valve [TGV 146] so as to control an ignition timing on the basis of an ignition timing map that is different from a valve opening time and a valve closing time of the intake air flow control valve comprises: a signal acquisition part 180 for acquiring an engine operating state; and an ignition timing control part 186 for changing over the ignition timing map to an ignition timing map under a valve opened state by delaying only by a delayed time from the changing-over of the intake air flow control valve when the engine operating state is kept at a prescribed operating state upon changing-over of the intake air flow control valve from the valve closed state to the valve opened state, and changing-over the ignition timing map to the ignition timing map under the valve opened state when the intake air flow control valve is changed over if the engine operating state is not kept at the prescribed operating state upon changing-over of the intake air stream control valve from the valve closed state to the valve opened state.SELECTED DRAWING: Figure 1
