This patent application describes a method of operating an internal combustion engine in a semi-closed or 'exhaust' cycle. The exhaust cycle is semi-closed in that no atmospheric air is introduced into the internal combustion engine. The engine can be switched back to an open or 'air' cycle, increasing fuel efficiency.
