Stirling engine performance testing apparatus
This is a very suitable teaching material for demonstrating thermal engineering, as it is a heat engine close to the Carnot cycle that heats and cools the gas inside the cylinder, converting the thermal energy from its volume changes into work. The power generated by the engine is converted into electrical energy (W) using a motor generator or into mechanical energy (Nm) using a torque meter. Additionally, experiments on a refrigeration cycle can be conducted using an external power source (sold separately). The included interface and software can display in real-time the cylinder pressure (kPa), rotational speed (rpm), cylinder volume (cm³), crank angle, and temperature data for both the heating and cooling sides of the displacer on a PC (sold separately), as well as plot P-V diagrams and estimate the efficiency of the Stirling engine.
