Abstract:
Provided is a signal generating device for an engine, comprising: a rotation sensor that is configured so as to output a signal each time a change in magnetic flux is detected, and that is fixed to a case of an engine; and a rotor provided with a reluctor for causing a change to occur in the magnetic flux detected by the rotation sensor each time the rotation position of a crankshaft matches a set rotation position. The signal generating device for an engine causes a signal to be outputted from the rotation sensor each time the rotation position of the crankshaft matches the set position. The reluctor is provided so that in one rotation of the crankshaft, a first signal pair comprising two signals generated successively with a first polarity and a second signal pair comprising two signals generated successively with a second polarity are generated once each from the rotation sensor.
