Document Type and Number:

WIPO Patent Application WO/2011/092734

Kind Code:

A1

Abstract:

An ignition control device for an engine is provided with a start-time ignition control unit which has a function of preventing the occurrence of kickback by retarding the ignition position of the engine or stopping ignition, a start-time rotational angle detection means which detects, as a start-time rotational angle, the rotational angle of a crankshaft from the start time of a starting operation of the engine, and a switching means which switches the control contents of the start-time ignition control unit according to the detected start-time rotational angle so that when the detected start-time rotational angle is less than a set angle, a kickback prevention effect is produced within a range in which the starting performance of the engine is not impaired, and when the detected start-time rotational angle is more than or equal to the set angle, a kickback prevention effect greater than the kickback prevention effect when the start-time rotational angle is less than the set angle is produced.
