Abstract
An ignition timing signal generating rotor adapted to be operatively coupled to the shaft of a distributor for an internal combustion engine is disclosed wherein the rotor generates an ignition timing signal in cooperation with an ignition timing sensor operatively coupled to the housing of the distributor. The rotor comprises a reluctance varying rotor portion of a magnetic material and a tube of a non-magnetic material carrying the magnetic rotor portion. The magnetic rotor portion and the non-magnetic tube are made of formed powder materials which are simultaneously sintered together into a single piece.
