2. Ignition magneto - Wikipedia

   en.wikipedia.org/wiki/Ignition_magneto

   The first car to use magneto ignition was the 1901 German Mercedes 35 hp racing car, followed by various cars produced by Benz, Mors, Turcat-Mery, and Nesseldorf. [8] Ignition magnetos were soon used on most cars, for both low voltage systems (which used secondary coils to fire the spark plugs) and high voltage magnetos (which fired the spark ...

3. Contact breaker - Wikipedia

   en.wikipedia.org/wiki/Contact_breaker

   These effects can largely be overcome using electronic ignition systems, where the contact breakers are retrofitted by a magnetic (Hall effect) or optical sensor device. However, because of their simplicity, and since contact breaker points gradually degrade instead of catastrophically failing, they are still used on aircraft engines.

4. Hall effect sensor - Wikipedia

   en.wikipedia.org/wiki/Hall_effect_sensor

   When electrons flow through a conductor, a magnetic field is produced. Thus, it is possible to create a non-contacting current sensor or ammeters. The device has three terminals. A sensor voltage is applied across two terminals and the third provides a voltage proportional to the current being sensed.

5. Current sensing - Wikipedia

   en.wikipedia.org/wiki/Current_sensing

   Fluxgate sensors or saturable inductor current sensors work on the same measurement principle as Hall-effect-based current sensors: the magnetic field created by the primary current to be measured is detected by a specific sensing element. The design of the saturable inductor current sensor is similar to that of a closed-loop Hall-effect ...

6. Capacitor discharge ignition - Wikipedia

   en.wikipedia.org/wiki/Capacitor_discharge_ignition

   Capacitor discharge ignition (CDI) or thyristor ignition is a type of automotive electronic ignition system which is widely used in outboard motors, motorcycles, lawn mowers, chainsaws, small engines, gas turbine-powered aircraft, and some cars.

7. Ignition system - Wikipedia

   en.wikipedia.org/wiki/Ignition_system

   As batteries became more common in cars (due to the increased usage of electric starter motors), magneto systems were replaced by systems using an induction coil.The 1886 Benz Patent-Motorwagen and the 1908 Ford Model T used a trembler coil ignition system, whereby the trembler interrupted the current through the coil and caused a rapid series of sparks during each firing.
