  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. 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 ...

  4. 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.

    en.wikipedia.org/wiki/Ford_Boss_302_engine

    The Ford Boss 302 (formally the "302 H.O.") is a high-performance "small block" 302 cu in (4.9 L) V8 engine manufactured by Ford Motor Company.The original version of this engine was used in the 1969 and 1970 Boss 302 Mustangs and Cougar Eliminators and was constructed by attaching heads designed for the planned 351 Cleveland (which debuted the following year) to a Ford small block.

  6. Internal combustion engine - Wikipedia

    en.wikipedia.org/wiki/Internal_combustion_engine

    The spark-ignition engine was a refinement of the early engines which used Hot Tube ignition. When Bosch developed the magneto it became the primary system for producing electricity to energize a spark plug. [37] Many small engines still use magneto ignition. Small engines are started by hand cranking using a recoil starter or hand crank.

  7. Capacitor discharge ignition - Wikipedia

    en.wikipedia.org/wiki/Capacitor_discharge_ignition

    Capacitor discharge ignition. CDI module. Capacitor discharge ignition (CDI) or thyristor ignition is a type of automotive electronic ignition system which is widely used in outboard motors, motorcycles, lawn mowers, chainsaws, small engines, turbine -powered aircraft, and some cars. It was originally developed to overcome the long charging ...

  8. Spark plug wires - Wikipedia

    en.wikipedia.org/wiki/Spark_plug_wires

    Spark plug wires. Four spark plug wires (distributor end on the right, spark plug end on the left) 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.

  9. Ignition timing - Wikipedia

    en.wikipedia.org/wiki/Ignition_timing

    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 ...
