Innovative Engineering: The M20-W-01 Stirling Engine is a masterclass in mechanical engineering, representing the α-type dual-cylinder, dual-piston Stirling model. This engine features two independent cylinders - one for generating heat and the other for cooling - working in unison to produce consistent and robust power. The engine's unique design results in a significant temperature difference between the hot and cold cylinders, ensuring continuous power output.
Sophisticated Design: Each cylinder in the M20-W-01 is equipped with a 20mm power cylinder and a 20mm stainless steel heating tube. The heating tube on the hot cylinder side is deliberately longer to optimize the compression ratio. Unlike traditional designs, the engine's two cylinder connecting rods are linked through a dual gear system with a 2:1 gear ratio. This design allows the crankshaft to rotate at 1000 RPM, propelling the 78mm diameter, 155g flywheel at 2000 RPM. The engine's design ensures smooth, stable operation, reminiscent of the mechanisms used in single-cylinder diesel engines to counteract strong vibrations.
Precision and Durability: To maximize the lifespan of the cylinders and pistons, the M20-W-01 utilizes bearing steel GCR15 for the cylinder sleeves and piston sleeves. After CNC machining, these components undergo hardening treatment to reach a hardness of 58-62 HRC, followed by precision grinding to achieve an accuracy of ±0.005mm. This precision is vital for sealing the gas within the cylinders and ensuring efficient reciprocating motion of the pistons - a hallmark of Stirling engine precision.
