How a Four‑Stroke Engine Works — The Crankshaft Trick

How a four-stroke gasoline engine works, in plain English — and the crankshaft trick that turns thousands of timed combustions into one smooth spin. See intake, compression, power, and exhaust in action, why each cylinder only fires once every two revolutions, and how firing order, cam timing, and spark advance make useful torque right after top dead center. We’ll unpack flywheels, harmonic dampers, and balance shafts, the real pressures inside a cylinder, why the crank floats on a microns-thin oil film, and how the ECU rides the edge of knock.
