Abstract:

This study experimentally investigated the effects of cam eccentric hole position and cylinder phase angle on the rotational speed and output power of a twin-cylinder Stirling engine. Experimental data were analyzed to identify the optimal combination of eccentric hole position and cylinder phase angle. The eccentric cam influences the piston's stroke and movement speed, which directly affect the engine's output power. Additionally, the cylinder phase angle impacts the continuity and stability of engine operation. Experimental results indicate that a cam eccentric distance of 5.5 mm leads to imbalanced piston motion and increased power consumption. In contrast, an eccentric distance of 5 mm combined with a cylinder phase angle of 80 degrees yields the lowest cam power consumption, thereby significantly enhancing the overall output efficiency of the Stirling engine.
