ABSTRACT:
An ignition system for a two-cycle engine which comprises a rotational body rotatable in synchronism with the crank shaft of the engine and having thereon a detectable portion extending circumferentially thereof, and a detector placed in the vicinity of the rotational body for detecting the circumferential edge portions of the detectable portion and for producing an electric signal containing amplitude variations appearing at the passage of the edge portions near the detector. The electric signal is processed by an ignition pulse generator which produces an ignition pulse at each time when a selected one of the amplitude variations of the electric signal occurs. The circumferential length of the detectable portion is selected so that the ignition pulse appears when the crank angle of the crank shaft is outside of the reverse rotation allowing angular region.
