ICE Spark Plug
The video discusses the importance of spark plugs in internal combustion engines.
It mentions the history of spark plugs, attributing the first documented use to Belgian engineer Jean Joseph Lenoir in 1859.
Early spark plugs used minerals like micia or porcelain as insulators and had a limited lifespan of about 600 miles.
With the emergence of leaded gasoline in the 1930s, spark plug construction shifted towards a single-piece design made of ceramic.
The evolution of spark plug design was driven by the need to handle increased power demands and aggressive deposit buildup.
