Abstract:
1. An engine ignition control apparatus comprising: an electronic control unit operatively connected to a plurality of sensors in an internal combustion engine of a vehicle, said plurality of sensors comprising a throttle position sensor and an engine speed sensor; a standard ignition map stored in a recordable data storage medium for retarding ignition timing when a detected throttle opening is in a control region in which the detected throttle opening is greater than or equal to a predetermined throttle opening, and when a detected engine rotary speed is within a predetermined rotary speed range; an acceleration-time advance angle correction quantity map stored in a recordable data storage medium for performing advance angle correction of an ignition timing in response to the engine rotary speed in the control region; an engine accelerometer for detecting a rate of change of the engine rotary speed during acceleration of the vehicle; and an acceleration-time advance angle correction quantity setting unit for setting the ignition timing at the time of correcting an advance angle; wherein, when the detected engine rotary speed is within said predetermined rotary speed range and a detected rate of change of engine rotary speed is greater than or equal to a predetermined rate of change of engine rotary speed, the acceleration-time advance angle correction quantity setting unit is operable:
