Abstract
An engine ignition control device comprising: a start-up ignition controller having a function for preventing the occurrence of kickback by either delaying an ignition position of an engine or stopping ignition; start-up rotation angle detection means for detecting a rotation angle of a crankshaft of the engine after initiation of a start-up operation of the engine; and switching means for switching control specifics of the start-up ignition controller in accordance with the detected start-up rotation angle so that when the detected start-up rotation angle is less than a set angle, there is created a kickback-preventive effect within a range at which engine startability is not compromised, and when the detected start-up rotation angle is equal to or greater than the set angle, there is created a kickback-preventive effect that is greater than the kickback-preventive effect for when the start-up rotation angle is equal to or less than the set angle.
