Abagogo:

I learned from somewhere many years ago that an engine used a fuel internally to produce work, while a motor took the energy from a fuel source at a distant location and produced work with it.

Internal combustion engine, steam engine, but electric motor. The fuel comsumed by the motor might have been combusted or fissioned (I suspect I am gonna hear about verbing a noun on this, but if something is fissionable it ought to fission!) many miles away.

I note that a steam engine is technically not an internal combustion engine, but the combustion generally occurs very close to the mechanical parts for the purposes of efficiency.
