Quick google definitions (not verbatim)

engine = machine that uses moving parts that converts power into motion, synonym with motor

motor = machine, especially one powered by electricity or internal combustion, that supplies motive power for a vehicle or for another device with moving parts.



sounds to me like they are essentially one and the same

Bummer. Based on some of the other responses I was thinking I was OK to ignore those "no motorized vehicles" signs, and start to drive my truck on the bike path.....

I was taught that internal combustion=engine, everything else=motor.

That makes solid-fueled rockets engines, and liquid-fueled rockets are motors. Glad we cleared that one up.

Regarding model airplane engines: Pretty much every manufacturer referred to their product as "engines".

Except Duke Fox who always referred to them as "motors".

The motor cooled down, the heat went down
And that's when I heard that highway sound.

Ain't never? Does that mean always?

I believe you can use motor and engine when talking about internal combustion, rotary, gas turbine, steam, etc. machines that convert whatever fuel source into a motion. But, an electric motor that turns a fan blade is not an engine (imo). A large (or several) large electric motors can be put in cars and used to replace engines but I believe those large electric motors are called motors.

I'm still on the motor and engine can be used interchangeably in some cases but motors are motors.

This could be a simple IQ question. If some motors are engines and some engines are motors then all motors are engines. True or false...FALSE

A friend of mine said he put a new motor in his car. Another friend said he put a rebuilt engine in his truck. Either way, I understood what both meant. Summer is but a few months away........................thank God.

All engines are motors.
Not all motors are engines.
Simple.

Neither "makes" power, they both just convert some form of stored energy into rotational motion.

You can have an electric motor but can you have an electric engine?

An engine always contains a motor, but a motor is not an engine. An engine is not a motor, an engine contains a motor, this is why it is confusing. The basic difference is power conversion vs power creation.

A motor converts power which is usable in one format, to power which is usable in a different format. IE:
1) electricity (which is power) spins a shaft
2) hydraulics (fluid power from pressure and flow) pushes a shaft in a cylinder
3) pumps/compressors (shaft spun by power input from external motor or external engine) compress and move a fluid

An engine creates its own power via energy input (usually heat from combustion), and then transforms that power into useable motion (this is the motor part). IE:
1) An internal combustion engine burns fuel and air, which creates heat and pressure, this is power. That heat and pressure, then pushes a crank slider mechanism, which converts power in the form of heat and pressure, into rotational power. The conversion of power is the motor portion.
2) A solid rocket engine creates its own power by burning solid rocket propellant and oxygen, which creates heat and fluid pressure and fluid flow. That fluid power is then expanded through a nozzle and transformed in a pressure distributed over an area on the bottom of the thrust cone. The conversion of power is the motor portion.
3) The human body processes food via a chemical reaction and produces some form of power which I don't fully understand. That power is transported to muscles which converts it via another chemical reaction which expands and contracts muscles, which allows movement. The conversion of power is the motor portion.

An engine is a conglomeration of multiple systems.

A motor is a single system.

An engine cannot exist without a motor, but a motor can never be an engine.

The Ecoboost is an engine and all Chevy's have motors in them

So we really have outboard engines but just say outboard motor because it sounds better?
