Title:
【発明の名称】エンジンの点火時期制御装置
Document Type and Number:
Japanese Patent JP2702551
Kind Code:
B2
Abstract:
A control system for controlling spark timing of the engine is to control the retarding of the spark timing at the time of accelerating in anticipation. The amount of retarding the spark timing at the time of accelerating is set larger when the torque converter is provided in a driving system of the engine than when no torque converter is provided. A preferred feature is such that the amount of retarding the spark timing at the time of accelerating is set so as to be decreased gradually from its given initial value and that the retarding of the spark timing is suspended when the retarding amount reaches a value smaller than a given reset value. Both the initial value and the reset value are set to be greater when the torque converter is equipped than those when no torque converter is equipped.
