Stirling Engine – Kinematic Educational Model

Design made from scratch with Solidworks and changed to Fusion for printing, in memory of the Scotland Engineer Robert Stirling, that came up with the first air engine in 1816.Threads are made with 0.2 tolerance.Bearings are printed and working.Moving parts, balance, rotors, pistons rods and junctions were tested for accuracy and dimensions.Intented for education.Phase RelationshipIn a typical Stirling engine, the displacer piston and power piston operate with a 90-degree phase difference.This means that when the displacer piston is at its TDC (fully up in the vertical cylinder), the power piston is either at its midpoint or nearing its BDC in the horizontal cylinder. This phase difference allows the gas to be appropriately heated and cooled, creating the necessary pressure variations to drive the power piston continuously.TIMINGCheck the assembly. If everything was fitted following this step-by-step procedure, there should be approximately a 90-degree phase difference between the flyw
