gasoline engine
Let an agent explain how gasoline engines work and how they are classified, identify notable engine families from reference sources, relay emissions and safety regulation, and distinguish gasoline engines from diesel and other engines.
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 how gasoline engines work and how they are classified, identify notable engine families from reference sources, relay emissions and safety regulation, and distinguish gasoline engines from diesel and other engines.
An internal combustion engine that burns petrol, or gasoline, with a spark-ignited air-fuel mixture in reciprocating cylinders, used in cars, motorcycles, small aircraft, boats and equipment, in configurations such as inline, V and flat, naturally aspirated or turbocharged; families include historical aero engines such as the Allison V-1710 and Maybach HL120 and automotive engines such as the Chrysler Hemi and Toyota JZ, and the type is increasingly regulated for emissions and being displaced by electrification.
What it is for: Powering vehicles and equipment.
It can be explain operation and classification; identify notable engine families; relay emissions and safety regulation; distinguish from other engines.
Distinguishing features
Spark ignition
Otto cycle
Wide range of sizes
Emissions regulation
What it looks like
A block with cylinders, pistons, spark plugs, intake and exhaust systems, mounted in a vehicle or machine.
Physical character
compression ratio: about 8-14 ratio - typical
thermal efficiency: about 25-40 percent - peak, modern engines
How it is recognised
Spark-ignition reciprocating engine burning petrol
Inline, V, flat and other layouts
Diesel engines use compression ignition; electric motors are not engines in this sense
