ABSTRACT:
Several embodiments of spark timing control for spark ignited internal combustion engines that improve running under certain adverse conditions. Arrangements are disclosed for reducing the speed of the engine in response to certain abnormal conditions, such as shifting of an associated transmission. The speed is reduced by interrupting the spark of the engine. In accordance with the disclosed embodiments, uneven running and stalling is avoided by advancing the spark if the engine speed falls below a predetermined engine speed.
