PURPOSE:To prevent ignition from being effected under a condition that suction and compression have not been effected normally and generating the sputtering of mixture by a method wherein igniting operation of an igniting circuit for the engine of four-cycle having more than two cylinders is stopped and held as it is for a predetermined time interval after starting. CONSTITUTION:When a starting switch 6 is closed, the igniting operation is not effected because of the OFF condition of a transistor 16, however, a signal of a high level is outputted from a time constant circuit 11 after a crankshaft is rotated at least more than one rotation. The transistor 16 is put ON by the signal, therefore, the igniting operation is effected thereafter and the ON condition of the transistor 16 is held by a thyristor 15, thereafter, the igniting operation may be maintained in stable. According to this operation, the ignition at the terminating time of a compression stroke may not be generated immediately after the starting and the sputtering may be prevented. |
