Magneto-flywheel ignition for combustion engines.

摘要

In the plastoferrite magnetic strip (13), that is to say the magnet made of plastic or ceramic material or the like, interacting with an armature carrying the induction coil and an electromagnetic angular-position sensor (19) having two magnetic branches (19A, 19B) possessing mutually opposed windings (VA, VB) designed to generate a signal as a result of an imbalance, there is a discontinuity (13A) in the plastoferrite strip (13), that is to say in the magnet made of plastic or the like, capable of modifying the magnetic field in only one of the two branches of the sensor (19).
