  2. Firing order - Wikipedia

    en.wikipedia.org/wiki/Firing_order

    The firing order of an internal combustion engine is the sequence of ignition for the cylinders. In a spark ignition (e.g. gasoline/petrol) engine, the firing order corresponds to the order in which the spark plugs are operated. In a diesel engine, the firing order corresponds to the order in which fuel is injected into each cylinder.

  6. 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 ...
