  2. Ignition system - Wikipedia

    en.wikipedia.org/wiki/Ignition_system

    An ignition magneto (also called a high-tension magneto) is an older type of ignition system used in spark-ignition engines (such as petrol engines). It uses a magneto and a transformer to make pulses of high voltage for the spark plugs.

  3. Engine control unit - Wikipedia

    en.wikipedia.org/wiki/Engine_control_unit

    An engine control unit (ECU), also called an engine control module (ECM), [1] is a device that controls various subsystems of an internal combustion engine. Systems commonly controlled by an ECU include the fuel injection and ignition systems.

  4. Ignition coil - Wikipedia

    en.wikipedia.org/wiki/Ignition_coil

    Ignition module for a 2003-2010 GM Z18XE engine Since the 1990s, ignition systems have mostly switched to a design where the distributor is omitted and ignition is instead electronically controlled. In these distributor-less systems, multiple smaller ignition coils are used, usually in the form of one coil for each cylinder or a wasted spark ...

  5. Capacitor discharge ignition - Wikipedia

    en.wikipedia.org/wiki/Capacitor_discharge_ignition

    CDI module. 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.

  6. High energy ignition - Wikipedia

    en.wikipedia.org/wiki/High_energy_ignition

    A predecessor system called "Unitized Ignition" was optional on 1972 and 1973 Pontiacs. [citation needed] Most—but not all—HEI systems have the ignition coil mounted in the distributor cap. A control module and magnetic pickup are mounted in the distributor, in place of a conventional ignition system's breaker points and condenser.

  7. Ford EEC - Wikipedia

    en.wikipedia.org/wiki/Ford_EEC

    Later models have the TFI module mounted on a heatsink in the engine compartment. It is prone to damage from heat. It was created with surface-mount technology parts, allowing it to be much smaller than the previous Dura-Spark ignition module. The ignition coil used is the E-Core design.

  8. Contact breaker - Wikipedia

    en.wikipedia.org/wiki/Contact_breaker

    Breaker arm with contact points at the left. The pivot is on the right and the cam follower is in the middle of the breaker arm. A contact breaker (or "points") is a type of electrical switch, found in the ignition systems of spark-ignition internal combustion engines.

  9. Ford EDIS - Wikipedia

    en.wikipedia.org/wiki/Ford_EDIS

    The Ford EDIS or Electronic Distributorless Ignition System is a computer-controlled ignition system developed by Ford that uses an ignition coil for each pair of cylinders (wasted spark). All the coils are placed in a single module called a coilpack.
