FLASHCARD QUESTION

Front

External Combustion Engine Noun

[ek-stur-nl kuhm-buhs-chn en-jin]

Back

External Combustion Engine


An engine that generates heat and power by burning fuel outside of the engine's main body.

Example: This diagram shows how steam, heated by an external source, pushes a piston. This movement turns a flywheel, converting the steam's thermal energy into mechanical work.

Front

Internal Combustion Engine Noun

[in-tur-nl kuhm-buhs-chn en-jin]

Back

Internal Combustion Engine


A heat engine where fuel combustion occurs inside a chamber that is part of the engine's working fluid circuit.

Example: This diagram shows a cross-section of an internal combustion engine, labeling key parts like the piston and crankshaft that convert fuel energy into motion.

FLASHCARD QUESTION

Front

Stroke Noun

[strohk]

Back

Stroke


In an engine, the full travel of the piston along the cylinder in either direction.

Example: This diagram shows the exhaust stroke in an engine, where the piston moves up to push waste gases out, a key step in converting fuel energy.

FLASHCARD QUESTION

Front

Crankshaft Noun

[krank-shaft]

Back

Crankshaft


A rotating shaft which converts the reciprocating motion of the pistons into rotational motion.

Example: This diagram shows how a crankshaft converts the back-and-forth (linear) motion of pistons into spinning (rotational) motion, transferring energy within an engine.

FLASHCARD QUESTION

Front

Coolant Noun

[koo-luhnt]

Back

Coolant


A fluid which flows through a device to prevent overheating by transferring heat away from it.

Example: This image shows a car's radiator system, where coolant circulates to absorb heat energy from the engine and release it into the air.

FLASHCARD QUESTION

Front

Regenerative Braking Noun

[ri-jen-er-uh-tiv brey-king]

Back

Regenerative Braking


An energy recovery mechanism that slows a vehicle by converting its kinetic energy into a storable or usable form.

Example: During braking, an electric car's motor reverses its function, converting the car's motion (kinetic energy) back into electrical energy to recharge the battery.

FLASHCARD QUESTION

Front

Convection Noun

[kuhn-vek-shn]

Back

Convection


The movement of heat by the actual motion of matter, such as the movement of heated parts of a fluid.

Example: This diagram shows how the sun heats the land, causing less dense warm air to rise and denser cool air from the sea to sink and move in, creating a convection current.
