An internal combustion heat engine, of which the architecture of one elementary “cylinder” includes 4 identical mobile couplings distributed about the Z axis of the engine, consisting of a segmented “piston” driven by the crank pin of a crankshaft and guided by a roller rolling in a slide. The crankshafts, which are parallel and synchronised by a gear mechanism, perform one revolution per cycle. Each piston includes a sliding surface that nearly touches the cylinder face of the adjacent piston, but on which the segmentation slides in sealed contact. The concave shape of the 4 overlapping faces encloses a chamber volume that changes cyclically: at a minimum, having a quasi-spherical shape during combustion, reducing the heat losses at the walls, and at a maximum, uncovering the ports allowing intake and exhaust via transfer units and manifolds with the possibility of more economical Miller/Atkinson distribution, via rotary plates. 1. A heat engine , internal combustion , alternating , having a fixed chassis assembly , comprising: [ [ [{'b': '51', 'one cylinder face (), with its surface ruled all over and generally concave according to a sliding axis W referenced relative to the piston assembly, and around which it is curved, with this axis being perpendicular to axis Z of the motor,'}, {'b': 52', '51', '53, 'one sliding surface () whose intersection with one edge of the cylinder face () is a sharp edge line, known as front edge () and'}, {'b': '52', 'one sealing device comprising the sliding surface (),'}], 'A piston assembly, consisting of at least, {'b': 30', '39, 'a cyclic drive and orientation mechanism (), consisting of at least one drive shaft (), in cyclic and monotone rotation, which drives and positions the piston assembly relative to the chassis assembly, according to a movement in a plane P that is perpendicular to axis Z of the motor,'}], 'A whole number N, where N is greater than or equal to 3, of moving parts that are likewise distributed at regular ...
