ABSTRACT:
Arithmetic operations of an ignition timing are carried out in an ignition timing operation circuit on the basis of an output signal from a signal generating means which generates signals for establishing the ignition timing to thereby obtain an advance angle characteristic in accordance with the number of revolution of the engine, and, at the same time, this increase or decrease in the number of revolution of the engine is converted to an increase or decrease in an electric potential, and then, by detecting a changing quantity per unit time of this electric potential and, when the changing quantity takes a value higher than a predetermined value, the ignition timing is further advanced or delayed to the ignition timing obtained from the result of the arithmetic operations in the abovementioned ignition timing operation circuit.
