engine
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.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
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.
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.
What it is for: Producing mechanical work from energy.
It can be explain the concept and classification; distinguish engines from motors; relay principles of major types; separate other senses.
Distinguishing features
Energy conversion to work
Many principles
Efficiency limits
Central to transport and industry
What it looks like
Varies from small motors to large turbines; typically a housing with moving parts and energy input.
How it is recognised
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
