Abstract
An ignition control device for an internal combustion engine, which controls the number of times of ignition operation such that it becomes neither too large nor too small, according to a flowing state of a mixture in a cylinder. In the ignition control device, a target ignition timing is used as an in-cylinder flow parameter indicative of the strength of a tumble flow generated in a cylinder. When the target ignition timing is more advanced than a predetermined reference position, it is determined that the tumble flow is strong, and multiple ignition control is executed by setting the number of times of ignition to a plurality of times, whereas when the former is more retarded than the latter, it is determined that the tumble flow is not strong, and normal ignition control is executed by setting the number of times of ignition to only once.
