The Spark Plug Story

The spark plug, a crucial component in gasoline internal combustion engines, has a rich history dating back to 1859 when Belgian engineer Jean Joseph Étienne Lenoir first used it in his coal gas and air engine. The design was refined by inventors like Nikola Tesla, Frederick Richard Simms, and Robert Bosch, with Bosch being the first to develop a commercially viable spark plug.
Spark plugs ignite the air-fuel mixture in the engine's combustion chamber by creating a spark between two electrodes separated by an insulator. The spark ionizes the gases in the gap, causing a rapid surge of electron flow that ignites the mixture, creating a controlled combustion event.
Early spark plugs used mineral insulators and had short lifespans. The introduction of sintered alumina in the 1930s improved insulation, strength, and thermal properties, allowing higher voltages and better self-cleaning capabilities. In the 1970s, lead-free gasoline and stricter emissions regulations prompted further redesigns, including the use of copper core electrodes to improve self-cleaning and prevent pre-ignition.
Multiple ground electrode plugs and surface-discharging spark plugs were explored in the following decades. The 1990s saw the introduction of coil-on-plug ignition systems and noble metal high-temperature electrodes, enabling higher voltages, stronger sparks, and longer service life.
Modern spark plugs also incorporate ionic-sensing technology, which allows the engine control unit to detect detonation, misfires, and optimize fuel trim and ignition timing for each cylinder. This level of control has pushed engine designs to be more efficient and powerful.
As electric vehicles become more prevalent, the spark plug's evolution may soon reach its end, with electricity both pioneering the emergence and likely ushering in the end of the internal combustion engine.

    Small correction in 13:05, higher octane fuel is more resistant to pre-ignition because it is less reactive, which is not the same as volatile 😉. This is the same as saying that the auto-ignition temperature of the fuel is higher.

    Edmond Berger, a freed slave, invented the spark plug in 1839. Berger is credited with the invention even though he did not obtain a patent. The spark plug is a key component of all engines, using electricity to pass a spark between two electrodes to ignite fuel and generate power.

    THE INVENTOR OF THE CERAMIC SPARK PLUG INSULATION IS LOUIS SEMPLE CLARKE, ONE OF THE FOUNDERS OF THE PRESENT AUTOCAR TRUCK CORPORATION! THIS IS THE OLDEST EXISTING AUTOMOTIVE BRAND IN THE USA! CLARKE WAS THE FIRST TO ENCLOSE THE ENGINE CRANKCASE, AND USE AN OIL PUMP, CIRCULATING OIL, RATER THAN OIL DRIP CUPS AND GREASE CUP LUBRICATION! CLARKE ALSO INVENTED THE LONGITUDINAL ENGINE, CLUTCH, TRANSMISSION, AND CENTER DRIVE SHAFT TO AN DIFFERENTIAL DRIVELINE, AND ELIMINATING THE PREVIOUS ALL CHAIN DRIVES ON EARLIER AUTOMOBILES! CLARKE ALSO PERFECTED BATTERY ,COIL,POINTS AND CONDENSER IGNITION SYSTEM, RATHER THAN AN MAGNETO TYPE STSTEM! CLARKE IS LITERALLY THE ARCHITECT OF THE MODERN AUTOMOBILE, BUT IS NEARLY UNKNOWN TODAY!

    GM Cadillac AERA has existed as a concept car for 14 years. Apparently GM is not going to do anything with air motors at all. Sad, because the crap they've been spewing outta detroit for the past 100 years or so has helped to destroy the planet according to some people. Anyway it would be fun to run your ROTARY WANKEL AIRMOTOR on a 20,000+ psi CFC AIR PRESSURE TANK and in-hub WHEEL MOTORS for 1000 mile range per fill-up of PRESSURIZED AIR. The whole RECIPROCATING PISTON AIR MOTOR idea is OVER, so anyone focusing on that is simply SABOTAGING the AIR MOTOR INDUSTRY'S AMAZING POTENTIAL. The ROTARY WANKEL AIRMOTORS such as those developed by ENGINEAIR AUSTRALIA can solve our surface and aircraft transportation issues very quickly. THE NEW ROTARY WANKEL AIRMOTORS can be adapted to VTOL AIRCRAFT, as I mentioned to GM CADILLAC perhaps 15 years ago. Any company that focuses on ROTARY WANKEL AIRMOTOR VTOL AIRCRAFT will dominate the worldwide transportation industry for the next 100 years, or at least until "FIELD PROPULSION" technology is adequately developed.

    ahhh, come on, how could anybody seriously believe in such a thing as a self-driving car? What would it do in a construction zone, or if a policeman was directing traffic, or in tight situations where a human has to think fast and make instant decisions, what come up in driving a car, all the time. Such as when another car cuts you off. Or a car is backing out of a driveway and doesn't see you. Or there's emergency vehicles coming and you have to pull over. Or somebody runs into you. Or the police want you (or the automatic car) to pull over? Or railroad crossings, how could the self-driving car handle THAT?
