  2. Spark plug - Wikipedia

    en.wikipedia.org/wiki/Spark_plug

    Spark plug with single side electrode An electric spark on the spark plug. A spark plug (sometimes, in British English, a sparking plug, [1] and, colloquially, a plug) is a device for delivering electric current from an ignition system to the combustion chamber of a spark-ignition engine to ignite the compressed fuel/air mixture by an electric spark, while containing combustion pressure within ...

  3. ACDelco - Wikipedia

    en.wikipedia.org/wiki/ACDelco

    Champion went to work producing spark plugs to be used in Buick automobiles. Champion and Durant formed "Champion Ignition Co." Very shortly later, the Stranahan brothers ("Champion Spark Plug Co.") informed them they could not use the name "Champion" as they had it trademarked. At that time the name was changed to reflect Champion's initials.

  4. Spark plug wires - Wikipedia

    en.wikipedia.org/wiki/Spark_plug_wires

    Spark plug wires (also called high tension leads) are electrical cables used by older internal combustion engines to transmit high-voltage electricity from the distributor to the spark plugs. Tension in this instance is a synonym for voltage .

  5. Capacitor discharge ignition - Wikipedia

    en.wikipedia.org/wiki/Capacitor_discharge_ignition

    Since the CDI system provides only a reduced duration spark, it's also possible to combine this ignition system with ionization measurement. This is done by connecting a low voltage (about 80 V) to the spark plug, except when fired. The current flow over the spark plug can then be used to calculate the temperature and pressure inside the cylinder.

  6. Electric spark - Wikipedia

    en.wikipedia.org/wiki/Electric_spark

    A spark on a spark plug Lightning is a natural example of an electric spark. An electric spark is an abrupt electrical discharge that occurs when a sufficiently high electric field creates an ionized, electrically conductive channel through a normally-insulating medium, often air or other gases or gas mixtures.

  7. Stratified charge engine - Wikipedia

    en.wikipedia.org/wiki/Stratified_charge_engine

    The spark plug and CVCC inlet were isolated from the main cylinder by a perforated metal plate. At ignition a series of flame fronts shot into the very lean main charge, through the perforations, ensuring complete ignition.

  8. Ignition system - Wikipedia

    en.wikipedia.org/wiki/Ignition_system

    A variation coil-on-plug ignition has each coil handle two plugs, on cylinders which are 360 degrees out of phase (and therefore reach top dead center (TDC) at the same time); in the four-cycle engine this means that one plug will be sparking during the end of the exhaust stroke while the other fires at the usual time, a so-called "wasted spark ...

  9. Dual ignition - Wikipedia

    en.wikipedia.org/wiki/Dual_ignition

    A Jabiru 5100 flat-8 four-stroke aircraft engine with dual ignition, with two spark plugs per cylinder and two distributors.. Dual Ignition is a system for spark-ignition engines, whereby critical ignition components, such as spark plugs and magnetos, are duplicated.
