This seems like a logical error. I don't understand how an internal combustion engine works, but I know it doesn't come from goblins jumping up and down inside.
replyThe fact that you know it literally means you understand, at least to some extent, how an internal combustion engine works (i.e. it is powered somehow by combustion, and jumping goblins are not combusting generally).
replyIf you would have zero knowledge about ICEs, how would you know?
