a device that ignites the fuel-air mixture in the engine cylinders
A spark plug is a small device in a vehicle's engine that creates a spark to start the burning of the fuel and air mixture in the combustion chamber. It is placed in each cylinder of the engine and is powered by electricity. When the spark plug fires, it triggers the fuel to burn, creating the explosion that moves the pistons and powers the vehicle. Spark plugs are important for starting the engine and maintaining its performance. Over time, spark plugs may wear out and need to be replaced to ensure the engine runs smoothly.
