Morphology

preignition = ignition (transparent) = pre + ignite + ion

The meaning is a straightforward technical instance of 'ignition happening before the normal point in time'.

Etymology

Preignition comes from pre- ('before') and ignite ('to start burning'), so it gives the simple image of burning that happens too early. So, preignition in an engine is when the fuel and air start burning 'before' the spark plug fires, which is why that early burn can damage the engine.
