2. Isotopes of iridium - Wikipedia

   en.wikipedia.org/wiki/Isotopes_of_iridium

   Iridium-192 (symbol 192 Ir) is a radioactive isotope of iridium, with a half-life of 73.83 days. [11] It decays by emitting beta (β) particles and gamma (γ) radiation. About 96% of 192 Ir decays occur via emission of β and γ radiation, leading to 192 Pt. Some of the β particles are captured by other 192 Ir nuclei, which are then converted ...

3. 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 ...

   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. Iridium - Wikipedia

   Iridium compounds are used as catalysts in the Cativa process for carbonylation of methanol to produce acetic acid. [92] [93] Iridium complexes are often active for asymmetric hydrogenation both by traditional hydrogenation. [94] and transfer hydrogenation. [95] This property is the basis of the industrial route to the chiral herbicide (S ...

6. Capacitor discharge ignition - Wikipedia

   Spark plug lifespan was increased to at least 50,000 miles and points lifespan was greatly extended from 8,000 miles to at least 60,000 miles. Points lifespan became a factor of rubbing block (cam follower) wear and the life cycle of the spring with some lasting almost 100,000 miles. The Hyland unit was tolerant of varied points gaps.
