Abstract

In an apparatus for controlling ignition of a general-purpose internal combustion engine in which an ignition signal is produced both in a compression stroke and in an exhaust stroke of a four stroke cycle, one of the ignitions to be conducted based on the produced two ignition signals is cut and an after-ignition-cut engine speed is detected. Then it is discriminated whether each of the two ignition signals was produced in the compression stroke or in the exhaust stroke based on a difference between an average engine speed and the after-ignition-cut engine speed, and the ignition is controlled based on the ignition signal discriminated to be produced in the compression stroke in the two ignition signals, thereby enabling to improve the duration life of an ignition plug, with simple and compact structure.
