Spark Plug
A spark plug is an essential component of an internal combustion engine that ignites the fuel-air mixture by producing an electric spark. In aviation, spark plugs are used in reciprocating engines, which are commonly found in small aircraft. The spark plug is located in the cylinder head and is connected to the magneto or ignition system. When the fuel-air mixture is compressed in the cylinder, the spark plug produces a spark that ignites the mixture, causing a controlled explosion that drives the piston and propels the aircraft. Spark plugs must be regularly inspected and replaced to ensure proper engine performance and prevent engine failure.
