In this article, we have designed and fabricated the gamma-type Stirling engine based on the compression ratio technique. This engine is attached on a parabolic dish of a solar collector. The engine shows a good performance in terms of compression ratio, external work, total pressure, and engine’s speed. Our engine offers the thermal efficiency of 30.59 % so that it can reach the output mechanical power of 0.934. The temperature difference of 137 K can maintain very well for the heat collection of the solar collector even when the weather conditions are poor. Furthermore, our materials are environmentally friendly and this design is expected to be in the applications of the solar tracker in the future.

Solar energy is one of the more attractive renewable energy sources that can be used as an input energy source for heat engines. In fact, any heat energy sources can be used with the Stirling engine. Stirling engines are mechanical devices working theoretically on the Stirling cycle, or its modifications, in which compressible fluids, such as air, hydrogen, helium, nitrogen or even vapors, are used as working fluids. When comparing with the internal combustion engine, the Stirling engine offers possibility for having high efficiency engine with less exhaust emissions. However, this paper analyzes the basic background of Stirling engine and reviews its existing literature pertaining to dynamic model and control system for parabolic dish-stirling (PD) system.
