Based on the mechanical analysis, the difference between the sparkplug and igniter plug based on the parts is that the spark plug sparks at the pre-designed interval, while the igniter plug spark all the time.
Spark Plug and Igniter plug are attached to the mechanical device engine crankshaft.
However, while spark plug only sparks when there is the upward and downward movement of the crankshaft and piston of the engine.
In contrast, the igniter plug sharks all the time to ensure the engine's fuel continues burning.
Hence, in this case, it is concluded that there are differences between the sparkplug and the igniter plug.
