Title: Ignition timing control device for internal-combustion engine
Inventor: SASAKI HIROSHI
IPC: F02P5/15
Filed: 1985-07-22
Abstract: PURPOSE:To prevent misfiring during deceleration and to prevent occurrence of Knocking during acceleration, by differently setting an allowable maximum variation in the ignition timing of an engine in dependence upon whether the engine falls in its deceleration condition or not, when the ignition timing greatly varies during, for example, a transient period. CONSTITUTION:When the ignition timing of an engine which is calculated in accordance with the operating condition of the engine, has a variation at the present time, which is greater than that at the previous ignition timing, the variation is compared with a maximum value which is determined depending upon whether it is during acceleration or deceleration. Further, it exceeds the maximum value, a value which are obtained by adding or subtracting this maximum value to or from the previous ignition timing and which is different between the time of acceleration and the time of deceleration, is delivered as the present ignition timing. Thereby a maximum spark retardation value in the decelerating condition of the engine is made less than that in the accelerating condition of the engine. Accordingly, misfiring is prevented by gradually changing the ignition timing during deceleration, and meanwhile, knocking which is liable to occur particularly during the initial stage of acceleration from a low speed condition may be prevented.
