⚙️ Slider-Crank Engine Lab: Piston Motion, Gas Pressure, Torque and Flywheel (2D)

Interactive 2D slider-crank engine: exact piston position, velocity and acceleration, a single-zone cylinder pressure model with a Wiebe burn, gas and inertia forces, rod and side loads, torque ripple, flywheel speed fluctuation and a firing-order strip for 1 to 4 cylinders, with five numerical checks (kinematics, work balance, force geometry, Otto limit, flywheel).
