Morphology
The meaning is directly compositional: 'auxiliary' (extra/backup) modifies 'engine' (machine), so a B1 learner who knows both words can infer it refers to a secondary or backup engine used to operate equipment or provide additional power. This follows a common adjective+noun pattern cross-linguistically, making the phrase immediately understandable from its constituents.
Etymology
Auxiliary engine puts together auxiliary (meaning 'extra' or 'helping') and engine (a 'motor'). Imagine a small motor on a ship that stays ready to help the main engines or run equipment when needed, so it means 'a small extra engine that provides power or backup'.
