Morphology

ignition = ignite (semi-transparent) = ignite + ion

Formally a nominalization of 'ignite', but the sense 'the mechanism that ignites an engine' is a specialized technical extension that learners may not infer from the base verb alone.

Etymology

Ignition comes from the Latin ignis, 'fire', and the same root is in ignite. In a car the ignition is the part that makes a small spark to start the engine, so the name links the idea of making 'fire' to starting the engine.
