> most people in the technical community Not this member of the technical community; an engine is simply something that makes something else go or achieve an end. In my field we have calculation engines, these are neither electric nor cyclical. And a motor is essentially the same thing. Engines can be steam, ICE, electric, programmatic, or even man powered (for instance a siege engine). Perhaps it's different where you come from or, perhaps, there is more than one technical community.
