In this arrangement, portions of all four strokes are occurring simultaneously. That is, while the intake process is occurring behind the piston element in the intake region of the intake/compression cylinder, the compression process is occurring in the compression region in front of the piston element.

L'invention consiste également à coupler structurellement le premier et le second cylindre par le biais d'un stator contenant un seul volume toroïdal et d'un rotor commun, le rotor et le stator définissant entre eux les deux cylindres toroïdaux. Les cylindres peuvent être configurés sur des côtés opposés du rotor, le long du bord périphérique du rotor, ou du même côté du rotor.
