1. Safety instructions

• Pour the fuel alcohol carefully into the alco-

holburner, making sure that none of it is spilt.

• Never fill the alcoholburner as long the wick is

still smoldering or another open flame is in close

proximity.

• Immediately close the fuel container after use.

• Keep away from the open flame.

• Caution! Only extinguish the flame by fitting the

cover provided for this purpose.

The Stirling engine becomes hot when it is operated

with an open flame.

• Do not touch the displacement cylinder during

or immediately after operation of the Stirling

motor.

• Allow the Stirling engine to cool before putting it

away.

2. Description

The Stirling engine can be used for qualitative and

quantitative investigations of the Stirling cycle.and

can be operated in three different modes: heat en-

gine, heat pump and refrigerator.

The displacement cylinder and piston are made of

heat-resistant glass; the working cylinder, flywheel

and transmission covers are made of acrylic glass.

This allows a very clear observation of the individual

motion sequences at all times. The crankshafts are

equipped with ball bearings and made of hardened

steel. The connecting rods consist of wear-resistant

plastic.

The integrated motor-generator unit with a 2-stage pul-

ley allows the generated mechanical energy to be con-

verted into electrical energy. A switchover mechanism

permits operation of an integrated lamp or external

loads, as well as a feeding of electrical energy in order to

simulate a heat pump or refrigerator.

By attaching the thin cord supplied with the appara-

tus to the threaded rod on the work piston, the

stroke length can be measured.
