⚙️ Slider-Crank Engine (3D): Pistons, Rods, Valves and Flywheel from the Exact Equations

3D slider-crank engine built with Blender and Three.js: pistons, rods, crank throws, valves and a flywheel driven by exact kinematics and a single-zone pressure model, with force arrows, torque and shaking-force graphs and five numerical checks (kinematics, work balance, force geometry, Otto limit, flywheel).
