ABSTRACT:
An engine ignition controller in which, when a transmission is set at the first speed stage, ignition timing is set on the basis of an angle advance characteristic for causing the output of an engine to be decreased. Immediately before a vehicle speed reaches a vehicle speed limit, ignition is carried out according to an ignition pattern having a misfire rate to cause an increase rate of the vehicle speed to be decreased; while, when the vehicle speed exceeds the vehicle speed limit, ignition is carried out according to an ignition pattern having a misfire rate to cause the vehicle speed to be reduced. Further, different speed limits are set for respective speed stages higher in speed stage number than a certain speed stage so that, when the vehicle speed exceeds the vehicle speed limits, ignition is carried out according to ignition patterns to cause the vehicle speed to be decreased.
