motors are a subset of engines.
That's the definition I like. Motors turns something else into motion; engines can do other thangs.
This may not be true in all areas. Local laws may vary.

I often wonder how much use the new math is to the average kid. Hard to learn, few immediate uses.Not one in a thousand will ever be a mathematician. I remember eighth grade teacher telling us :" All horses are quadrupeds, but not all quadrupeds are horses."
I use that analogy far more often than subsets.

Well i had new math-- long before most, since my school used to cut cost for text books by always offering to be a pilot for new books and curiculums (more work for the teachers, but the teachers where all nuns, and didn't have much say.)
since i had new math, when my cousins still had old math, i saw a bit of both.. i like new math. some stuff, at the time seemed total stupid-- like numbering systems.. I could see no use for binary or octal.. but 20 odd years later, when i got a computer in 1982, and had to use binary and hexidecimal, Bing! it all came back to me, clear as a bell.
and learning Hex was so easy, since i already was primed to learn numbering systems! i can add and subtract in binary-- i don't have to convert to decimal, and i can do very simple multiplicaion, (times 2!) too! and i am one of a select group that knows octal! and as Musick, and some others know, i even know octal jokes! (request by PM)
i loved new math for the most part... and still love math!

It isn't (at least by me.)

I really hated it. I could do arithmetic, but I didn't do it like they wanted. And there were some things it took me a long time to understand. I think my main problem is that I wasn't psychologically prepared for it.

I even tried to learn fractal math, but it defeated me.

This would be great if the internal combustion engine in your car weren't also referred to as a motor.
Good that it is, too, otherwise General Motors might have named their company General Engines and then where would we all be?

As it is often the case with "near synonyms", the difference between the terms is not so much in the objects they denote than in the point of view they represent: "Engine" evokes the fact that the contraption in cause is the fruit of human genius (rather than nature), while "motor" is the pragmatic, functional word for the "black box" that drives something.
