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 reciprocating engines by type and cycle, help with identification, maintenance and troubleshooting at a general level, and cover history, regulation and the transition to other power sources.

A heat engine that uses one or more pistons moving back and forth in cylinders to convert pressure into rotating motion, including petrol and diesel internal combustion engines, opposed-piston designs such as the Napier Deltic and Junkers Jumo diesels, and steam and Stirling engines; the dominant engine type in cars, ships, aircraft and generators for over a century.

What it is for: Converting fuel energy into mechanical work.

It can be explain engine cycles and configurations; identify an engine type from features; explain common faults and maintenance; describe notable historic engines.

Distinguishing features

Piston and cylinder

Reciprocating to rotary conversion

Two- or four-stroke cycles

Many fuels and configurations

What it looks like

Blocks with cylinders, pistons, crankshaft, valves and ancillaries.

How it is recognised

Cylinders in line, V or opposed layouts

Crankshaft output

Turbines and rotary engines have no reciprocating pistons
