The historical concept of thermal engines based on four strokes taking place in one single capsulism (volumetric device) is currently reaching the limits of its perfectibility. It is therefore legitimate to begin trying to conceive radical departures from this well-rooted paradigm. This paper describes one of them, based on the use of two volumetric devices linked in a particular way and a continuous combustion which can be internal or external. The theoretical figures for specific power and efficiency are quite compatible with automotive uses as well as other features needed in these applications.
