Electrics & Electronics: Ignition Systems: Electronic systems & components

Induction	In electronic ignition systems the contact breaker is eliminated and the primary circuit is switched or triggered electronically.
Inductive system operation	Low inductive ignition coils have a low number of primary turns and a low primary resistance. The ignition module limits maximum primary current to a safe value.
Induction wiring	Inductive type pulse generators use the principles of electro-magnetic induction to produce an AC voltage. This can be used to signal an ignition module to turn the primary circuit 'on' and 'off'.
Hall effect sensors	A Hall effect sensor provides voltage pulses that are generated by alternately shielding the sensor from a magnetic field, then exposing it.
Hall effect operation	Voltage pulses from a Hall generator can be used by an ignition module to control the operation of the primary circuit.
Optical type sensors	Optical type sensors inside the distributor can be used to sense crank angle position. This information can be used by an engine management electronic control unit, to control ignition system operation.
