Hi everyone 👋
Can the FFH engine change it's mode of operation, from Atkinson cycle to Otto?

The only thing that turns the FFH engine from an Otto cycle to an Atkinson cycle is intake valve timing.  It can hold the intake value open longer and allow the piston to push some air back out of the cylinder and into the intake manifold.  Since the FFH engine has variable intake valve timing it could switch from Atkinson to Otto
