The original Atkinson cycle had an articulated crankshaft to provide a power stroke longer than the compression stroke, while the currently-called Atkinson cycle doesn't. It's basically closer to the Miller cycle, altough without the supercharger which is used in the Miller cycle to overcome the output reduction.
