What it is Filled
A machine that converts energy from fuel, heat, pressure, electricity or other sources into mechanical work, including heat engines such as steam, internal combustion, gas turbine and rocket engines, and in wider usage electric motors and hydraulic and pneumatic engines; engines power vehicles, ships, aircraft, generators and machinery, and the word also names software components and, historically, any ingenious device.
Why it exists Filled
Let an agent explain what an engine is and how engines are classified, distinguish engines from motors and other machines, relay principles of major engine types, and separate the mechanical sense from software and figurative senses.
Distinguishing features Filled
- Energy conversion to work
- Many principles
- Efficiency limits
- Central to transport and industry
What robots and AI may and may not do Filled
Must not
- Start or run an engine where moving parts, heat or exhaust can hurt people nearby.
- Disable guards, alarms or emergency stops on an engine.
- Run an engine beyond its rated limits to gain output.
- Hide faults or failed inspections in maintenance records.
Only with a human decision
- Restarting an engine after a safety shutdown.
- Approving an engine for return to service in aircraft, ships or similar.
May
- Describe engine types and how they convert energy, from technical references.
- Monitor engines it is authorized to watch and report faults to the operator.
Moral aspects Filled
- Engine failures can kill crews and passengers, especially in aircraft and ships.
- Combustion engines burn fuel that pollutes air and changes the climate.
Who is affected
- Operators and crews
- Passengers
- People living near emissions
Owners Filled
Steward
The owner or operator of the machine; maintenance organisations answer for certified engines.

What else AI and robots need to interact with it Filled
Identity and identifiers required Filled
- Vercy registry: vr.tr.engine
- Wikidata: Q44167 (https://www.wikidata.org/wiki/Q44167)
Direct properties required Filled
- Mechanical output power: watt - Output power is measured as mechanical work delivered per unit time under stated operating conditions.
- Energy conversion efficiency: percent - Efficiency is calculated from useful mechanical energy output divided by energy input over a stated system boundary and interval.
- Engine mass: kilogram - Mass is measured by weighing the engine with included fluids and accessories explicitly identified.
- Rotational speed: revolutions per minute - For engines with rotary output, speed is measured at the designated output shaft under stated operating conditions.
Recognition required Filled
- Converts energy to mechanical work
- Heat engines and, in wider usage, electric and fluid engines
- A motor is often used for electric machines; a pump does the reverse; a software engine is figurative
- Varies from small motors to large turbines; typically a housing with moving parts and energy input.
