Abstract
An ignition timing regulating device for use in an internal combustion engine for regulating the ignition timing of the engine depending on the pressure of ambient atmosphere. Based on the fact that the pressure in the intake manifold of the engine is equal to the pressure of ambient atmosphere in the starting stage of the engine, the output of a pressure sensor sensing the intake manifold pressure in the engine is applied to an atmospheric pressure sensing circuit so as to sense the value of atmospheric pressure in the engine starting stage, and the output of this atmospheric pressure sensing circuit is used for correcting the ignition timing of the engine.
