  2. Engine knocking - Wikipedia

    en.wikipedia.org/wiki/Engine_knocking

    In spark-ignition internal combustion engines, knocking (also knock, detonation, spark knock, pinging or pinking) occurs when combustion of some of the air/fuel mixture in the cylinder does not result from propagation of the flame front ignited by the spark plug, but when one or more pockets of air/fuel mixture explode outside the envelope of the normal combustion front.

  3. Ignition switch - Wikipedia

    en.wikipedia.org/wiki/Ignition_switch

    An ignition switch, starter switch or start switch is a switch in the control system of a motor vehicle that activates the main electrical systems for the vehicle, including "accessories" (radio, power windows, etc.).

  4. 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.

  5. Starter solenoid - Wikipedia

    en.wikipedia.org/wiki/Starter_solenoid

    This causes the starter solenoid to close a pair of heavy contacts, thus relaying a large electric current through the starter motor, which in turn sets the engine in motion. [ 1 ] The starter motor is a series, compound, or permanent magnet type electric motor with a solenoid and solenoid operated switch mounted on it.

  6. 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 ...

  8. Aircraft engine starting - Wikipedia

    en.wikipedia.org/wiki/Aircraft_engine_starting

    Turning the engine" with the ignition and switches accidentally left "on" can also cause injury, as the engine can start unexpectedly when a spark plug fires. If the switch is not in start position, the spark will occur before the piston hits top dead center, which can force the propeller to violently kick back.

  9. Back-fire - Wikipedia

    en.wikipedia.org/wiki/Back-fire

    When the flame moves backward it may also be called a "pop-back". A backfire can be caused either by ignition that happens with an exhaust valve open or unburnt fuel making its way into the hot exhaust system. A visible flame may momentarily shoot out of the exhaust pipe. A backfire is often a sign that the engine is improperly tuned.
