Sorry, this comment is probably better suited to the “English language hamsterwheel” thread, but both of your links would suggest that langleybaston is correct in saying that it should be “fewer” engines. Engines are “countable nouns” - therefore “fewer” is correct.
(E.g. “less sand” vs. “fewer grains of sand” - sand is not countable, grains are, as are engines)
