Quantitative Transparent Stirling Engine

For quantitative investigations of the Stirling cycle. The Stirling engine can be operated in three different modes: as a heat engine, heat pump and refrigerating machine.

The displacement cylinder and displacement piston are made of heat-resistant glass; the power cylinder, flywheel and gearbox cover are made of acrylic glass. This allows very clear observation of the individual sequences of motion at all times. The crankshafts have ball bearings and are made of hardened steel. The connecting rods are made of wear-resistant plastic.

The glass of the displacement cylinder is also equipped with recessed temperature measurement sockets before and behind the displacement piston, to allow measurements of temperature differences during operation as a heat pump or refrigerating machine.

The large flywheel made of acrylic glass has imprinted markings to allow measurement of revolutions per unit of time using a light barrier.

For recording pV-diagrams, it is possible to measure the pressure in the power cylinder via a hose connection; the string included in the scope of delivery can be fastened to the power piston to measure the stroke in order to determine the volume.

The integrated engine – generator unit with a two-stage belt pulley allows a conversion of the produced mechanical energy into electrical energy. Equipped with a switchover option for operating an integrated lamp or external loads, or feeding electrical energy for operation as a heat pump or refrigerating machine, in accordance with the direction of rotation of the Stirling engine. Includes an alcohol burner (U10051)
