Patent JP-S60164667-A (JP)
Title: Distributor
Inventor: HINO TOSHIYUKI
IPC: F02P7/067
Filed: 1984-02-06
Abstract: PURPOSE:To prevent erroneous operation and the generation of early ignition and knocking by arranging an ignition coil so that the axis of a main magnetic flux due to the electric conduction of the primary coil crosses at right angles with a rotary shaft and the direction of the induction of the magnetic flux of a revolution-signal generating means. CONSTITUTION:When the magnetic flux PHIs for signals which crosses with a pick-up coil 4d through the revolution of a signal rotor 4a varies in correspondence, a signal voltage Vs is generated onto the coil 4d and is input, and an ignition control unit controls the electric conduction of an ignition coil. Therefore, a magnetic flux is generated by the primary current I1 which flows in the primary coil 2a, and the leak magnetic flux PHIl is distributed in correspondence with the primary current I1 which flows in the primary coil 2a. The signal voltage Vs generated in the coil 4d generates the normal wave-form which is not influenced by the leak magnetic flux PHIl, since the leak magnetic flux PHIl does not cross with the coil 4. Therefore, normal operation is repeated without generating erroneous operation, since the ignition control unit is operated, and the generation of early ignition and knocking can be prevented.
