Abstract

Concern for the environment and the impact of climate change has spawned various technological innovations for high-efficiency engines that save fuel and produce less carbon emissions. One of the technological innovations that attracted attention was the Stirling engine. The Stirling engine is a closed cycle regenerative engine with an external combustion system. This machine works by converting heat energy into mechanical energy. Because it operates on a closed cycle and can use a variety of heat sources for its operation, the engine produces no emissions at all. The efficiency of this machine is also very high, therefore this machine has enormous potential as an alternative driving engine that is environmentally friendly in the future. This study aims to design a Stirling engine type Alpha with a capacity of 228 cc with a phase angle of 90°, then analyze its performance in the form of power indicators and thermal efficiency indicators, and determine the effect of increasing the temperature difference between the compression chamber temperature and the expansion chamber temperature on the engine rotation speed. The method used to analyze engine performance is the Schmidt method, which is a Stirling engine performance analysis method based on isothermal expansion and ideal gas compression. The result of this research is that the Stirling engine which is designed starts working when the compression chamber temperature is 31,9°C and the expansion chamber temperature is 482,2°C. The highest engine speed is 598 rpm which is obtained at a compression chamber temperature of 45,5°C and an expansion chamber temperature of 662,4°C. The engine power indicator is 194,6 Watt at 598 rpm, while the thermal efficiency indicator is 65,94%. Based on the test data, it is also known that the increase in temperature difference between the compression chamber temperature and the expansion chamber temperature causes an increase in engine rotation speed. Keywords : Alpha Stirling Engine, Schmidt’s Theory, Power, Thermal Efficiency, Temperature Difference.
