Fabrication and testing of a gamma type stirling engine

Abstract The paper presents the manufacturing and design aspects of a gamma type Stirling engine using spirit lamp flame as its heat source. A small scale model of the engine is developed with 10 cc swept volume. The engine was tested two times. Vital observations and data collection was done during the first test. After incorporating sufficient modification on the engine with the observations of the first test, second test was conducted successfully. The speed of the engine during the working was monitored. The engine attained maximum speed up to 2000 rpm. When the engine could not produce the required temperature difference, speed was dropped down to 500 rpm. This study also includes the various manufacturing processes carried out during the engine development. This data and engine can be used for future reference model, since Stirling engine has the potential to become Green engine.
