2. Ignition coil - Wikipedia

   en.wikipedia.org/wiki/Ignition_coil

   An ignition coil is used in the ignition system of a spark-ignition engine to transform the battery voltage to the much higher voltages required to operate the spark plug(s). The spark plugs then use this burst of high-voltage electricity to ignite the air-fuel mixture. The ignition coil is constructed of two sets of coils wound around an iron ...

3. Trembler coil - Wikipedia

   en.wikipedia.org/wiki/Trembler_coil

   A trembler coil, buzz coil or vibrator coil is a type of high-voltage ignition coil used in the ignition system of early automobiles, most notably the Benz Patent-Motorwagen and the Ford Model T. [2] Its distinguishing feature is a vibrating magnetically-activated contact called a trembler or interrupter , [ 3 ] [ 1 ] which breaks the primary ...

4. Capacitor discharge ignition - Wikipedia

   en.wikipedia.org/wiki/Capacitor_discharge_ignition

   This system worked like all Kettering (points/coil) ignition systems: the opening points trigger the collapse of the magnetic field in the ignition coil, producing a high voltage pulse which flows through the spark plug wire to the spark plug. Some electronic ignition systems exist that are not CDI. These systems use a transistor to switch the ...

5. Induction coil - Wikipedia

   en.wikipedia.org/wiki/Induction_coil

   Antique induction coil used in schools from around 1900, Bremerhaven, Germany. An induction coil or "spark coil" (archaically known as an inductorium or Ruhmkorff coil [1] after Heinrich Rühmkorff) is a type of transformer [2] [3] [4] used to produce high-voltage pulses from a low-voltage direct current (DC) supply.

6. 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.

7. Contact breaker - Wikipedia

   en.wikipedia.org/wiki/Contact_breaker

   A mechanism may be provided to slightly adjust timing to allow for varying load on the engine. Since these contacts operate frequently, they are subject to wear, causing erratic ignition of the engine. More recent engines use electronic means to trigger the spark, which eliminated contact wear and allows computer control of ignition timing.
