While most rotary engines use the principle of volume variation between a curve and a moving cord of fixed length, this new engine concept uses a four degrees of freedom X, Y, .theta., .PHI. rotor, confined inside an internal housing contour, and does not require a central shaft or support. The invention is an assembly of four carriages supporting the pivots of four pivoting blades forming a variable-shape rotor. This rotor rolls just like a roller bearing on the surface of an housing internal contour wall shaped like a skating rink. During the rotation, the rotor pivoting blades align alternatively in a lozenge and a square configuration. All ports are radial in the housing and/or axial on the lateral side covers. Since the compression and expansion strokes start and end simultaneously, an ignition flame transfer slot is used to maintain a continuous combustion while four strokes are completed in every rotation. A central shaft is not needed for the engine to operate, but can be added and driven by the blades, through a mechanical arms coupling. The device incorporates few parts, does not need a crankshaft or a flywheel, and can be made strong enough to meet the criteria of photo-detonation and direct hydrogen combustion.
