  2. Ignition coil - Wikipedia

    en.wikipedia.org/wiki/Ignition_coil

    The ignition coils for these can be combined into a single casing (a coil pack) and located away from the spark plugs; however it is increasingly common for coil-on-plug systems to be used, whereby the individual ignition coils are small units attached directly to the top of each spark plug. An advantage of coil-on-plug systems is that in the ...

  3. Timing light - Wikipedia

    en.wikipedia.org/wiki/Timing_light

    Timing light, combination instrument with RPM, volt meter and dwell angle meter. The actual light is on the far end. The black clamp connects to the battery -, the red clamp to +, the green one to the breaker side of the coil (for RPM), the big black clamp in the foreground is an inductive pick-up that clamps around a spark plug wire.

  4. Multimeter - Wikipedia

    en.wikipedia.org/wiki/Multimeter

    The meter movement in a moving pointer analog multimeter is practically always a moving-coil galvanometer of the d'Arsonval type, using either jeweled pivots or taut bands to support the moving coil. In a basic analog multimeter the current to deflect the coil and pointer is drawn from the circuit being measured; it is usually an advantage to ...

  5. Ignition timing - Wikipedia

    en.wikipedia.org/wiki/Ignition_timing

    Pressure in cylinder pattern in dependence on ignition timing: (a) - misfire, (b) too soon, (c) optimal, (d) too late. In a spark ignition internal combustion engine, ignition timing is the timing, relative to the current piston position and crankshaft angle, of the release of a spark in the combustion chamber near the end of the compression stroke.

  6. Growler (electrical device) - Wikipedia

    en.wikipedia.org/wiki/Growler_(electrical_device)

    A growler is an electrical device primarily used for testing a motor for shorted coils. A growler consists of a coil of wire wrapped around an iron core and connected to a source of alternating current. When placed on the armature or stator core of a motor the growler acts as the primary of a transformer and the armature coils act as the ...

  7. Electric spark - Wikipedia

    en.wikipedia.org/wiki/Electric_spark

    The voltage for the spark is provided by an ignition coil or magneto that is connected to the spark plug with an insulated wire. Flame igniters use electric sparks to initiate combustion in some furnaces and gas stoves in place of a pilot flame . [ 7 ]

  8. Capacitor discharge ignition - Wikipedia

    en.wikipedia.org/wiki/Capacitor_discharge_ignition

    When the triggering circuit receives the triggering signal, the triggering circuit stops the operation of the charging circuit, allowing the capacitor to discharge its output rapidly to the low inductance ignition coil. In a CD ignition, the ignition coil acts as a pulse transformer rather than an energy storage medium as it does in an ...

  9. 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 ...
