Abstract
The design of an external heat input motor (EHIM) that operates according to the Stirling cycle is considered. This engine can convert low-temperature heat from 40 to 100°C into mechanical energy and then into electricity. Such an engine is effective for off-grid power supply, especially in remote areas where access to electricity is difficult. We propose a modernization of the design by increasing the volume of the displacer, resulting in a lower operating temperature of the heater. Experimental results presented in the paper confirm the efficiency of this design in converting low-potential heat, which makes it promising for use in autonomous power systems.
