This low-temperature model is used to demonstrate

the operation and basic design of a Stirling engine.

1. Safety instructions

• The Stirling engine does not need any lubrication.

• Avoid exposure of the device to dust.

• Do not clean the device with acetone or similar sol-

vents.

2. Description, technical data

The low-temperature Stirling engine can be powered

by the warmth of the human hand alone. It only re-

quires a temperature difference of about 5°C between

the bottom and top plates.

The operating cylinder consists of precision glass, while

the displacement cylinder and flywheel are made of

acrylic glass. This allows the movement of the operat-

ing piston, displacement piston and crank mechanism

to be observed clearly. The crankshaft and connecting

rod are furnished with high-precision miniature ball

bearings in order to minimize losses due to friction.

The matt black coating of the top plate also allows the

Stirling engine to run on solar energy.

Speed: Approximately 80 rpm at ∆T 1 0 º C

Flywheel: 110 mm Ø

Dimensions: 138 mm x 110 mm Ø

3. Procedure

• Place the Stirling engine on your hand or any other

warm surface, e.g. across the rim of a cup of coffee.

• The bottom plate will heat up sufficiently after 1

or 2 minutes. In warm weather, the temperature

difference might prove too small, in which case the

top plate would need to be cooled with a moist

cloth.

• Set the flywheel in clockwise motion (relative to the

front end of the crankshaft).

• The Stirling engine will turn anti-clockwise if the

top plate heats up, for instance, through solar ra-

diation or warmth emanated by a lamp. For this

purpose, place the engine on a cool surface such

as a window sill.
