  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. Wasted spark system - Wikipedia

    en.wikipedia.org/wiki/Wasted_spark_system

    Wasted spark system. 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. The extra spark during the exhaust stroke has ...

    en.wikipedia.org/wiki/Iridium

    Iridium is a chemical element; it has symbol Ir and atomic number 77. A very hard, brittle, silvery-white transition metal of the platinum group, it is considered the second-densest naturally occurring metal (after osmium) with a density of 22.56 g/cm 3 (0.815 lb/cu in) [8] as defined by experimental X-ray crystallography. [a] 191 Ir and 193 Ir ...

  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 iron ...

  7. Mitsubishi 4B1 engine - Wikipedia

    en.wikipedia.org/wiki/Mitsubishi_4B1_engine

    According to Mitsubishi, the new cylinder dimensions contribute to a free-revving character (max power at 6500 rpm), linear power delivery and wide torque curve. Mitsubishi used a timing chain instead of a belt for better reliability and iridium spark plugs to lower emissions and to help extend major service intervals for lower cost of ownership.
