Abstract
The invention provides a stroke discriminator of an internal combustion engine which can quickly identify the stroke of the internal combustion engine. A rotor operatively associated with a crankshaft of a single cylinder internal combustion engine is provided on the outer periphery thereof with a plurality of detected elements. The rotor is provided, on the outer periphery thereof, with a detected element formed-region having a plurality of detected elements formed thereon at equal angle intervals in the rotational direction and a non-formed region having no detected elements formed thereon. The non-formed region has an angle interval greater than the equal angle interval, and provided on the rotor to pass near detector means when the piston of the internal combustion engine travels from the top dead center to the bottom dead center.
