The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.

Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.

Thank you for breaking down the definition. I’d heard that about motors as “energy converters” but not specifically the definition difference of engines needing a “self sustaining fuel source”. All engines are technically heat powered motors, but only heat powered motors are engines then, right?
Not all engines are heat powered motors, and vis versa. I should have clarified earlier as well, but motors convert energy into motion. Engines have a motor, but contain other systems and accessories to aid the motor, and have the potential to create other forms of energy from that conversion process.
Think of an engine as a self-contained package, also known as an assembly. Multiple systems come together to form the engine. You give it fuel, and it converts that fuel into heat, rotational motion, electricity, and cooling. It also lubricates and cools itself. The piston/crank system is the motor component of the engine. The intake, exhaust, and cooling systems are part of the engine, and they allow the motor to keep working efficiently. The alternator and AC compressor are engine accessories.
It gets much easier to understand if you picture other types of engines. In a jet engine, the turbine section is the motor core of the engine. On a steam engine, the motor is the steam piston component that drives the wheels.
I edited my original comment to help clear up the half-asleep explanation I gave before.
