'diesel-fueled' originates from the name 'Rudolf Diesel', the inventor of the diesel engine, combined with 'fuel', which comes from Old French 'fouaille', meaning 'firewood'.

'Diesel' was named after Rudolf Diesel, and 'fuel' evolved from the Old French word 'fouaille', eventually becoming the modern English word 'fuel'.

Initially, 'fuel' meant 'firewood', but over time it evolved to mean any material that can be burned to produce energy.
