  2. High energy ignition - Wikipedia

    en.wikipedia.org/wiki/High_energy_ignition

    The HEI system has 40% more voltage output and 85% higher energy level than conventional breaker point systems to fire lean fuel mixtures even under adverse conditions. There were many design variations over the years, and provisions for computer controls were added for some applications starting in the late 1970s.

  3. Spark plug wires - Wikipedia

    en.wikipedia.org/wiki/Spark_plug_wires

    A coil wire is of the same construction as a spark plug wire, but generally shorter and with different terminals. Some distributors have an ignition coil built inside them, eliminating the need for a separate coil wire, such as the High Energy Ignition (HEI) system used by General Motors in the 1970s and 1980s.

  4. Wasted spark system - Wikipedia

    en.wikipedia.org/wiki/Wasted_spark_system

    Ignition system of a flat-twin Citroën 2CV. A wasted spark system is a type of ignition system used in some four-stroke cycle internal combustion engines.In a wasted spark system, the spark plugs fire in pairs, with one plug in a cylinder on its compression stroke and the other plug in a cylinder on its exhaust stroke.

  5. 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 ...

  6. Capacitor discharge ignition - Wikipedia

    en.wikipedia.org/wiki/Capacitor_discharge_ignition

    Some electronic ignition systems exist that are not CDI. These systems use a transistor to switch the charging current to the coil off and on at the appropriate times. This eliminates the problem of burned and worn points, and provides a hotter spark because of the faster voltage rise and collapse time in the ignition coil.

  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.

    Delete anything you haven't used in more than six months. While you're at it, uninstall unnecessary add‑ons such as toolbars, plug‑ins, and extensions. Step #2: Get antivirus software

  9. 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.
