Abstract[English]
The invention is a compact and streamlined internal combustion rotary engine featuring simple geometric shapes and a minimal number of components. It optimizes performance by producing more power strokes per revolution and incorporates a straightforward operational mechanism that enhances efficiency. This design ensures improved reliability and fuel efficiency, enabling high performance, a high power-to-weight ratio, durability, and economical efficiency. The engine mainly comprises of a structural frame base (1) mounted with at least one piston rotary head (40) and at least one chamber rotary head (10) that are configured to engage together. The piston rotary head (40) comprises of five curved pistons (41, 42, 43, 44, and 45) configured around its perimeter. The chamber rotary head (10) comprises of five chambers (11, 12, 13,14, and 15) configured around its perimeter. The engine further comprises openings for fresh air intake (5, 6, 7, and 8) and exhaust gas scavenging (57 and 58), fuel injectors (9) and fuel ignition configuration.[French]
L'invention concerne un moteur rotatif à combustion interne compact et simplifié présentant des formes géométriques simples et un nombre minimal de composants. Ce moteur optimise les performances en produisant plus de courses de puissance par révolution et incorpore un mécanisme opérationnel simple qui améliore l'efficacité. Cette conception assure une fiabilité améliorée et l'efficacité du carburant pour une performance élevée, un rapport puissance/poids élevé, une durabilité et une efficacité économique. Le moteur comprend principalement une base de cadre structural (1) montée avec au moins une tête rotative de piston (40) et au moins une tête rotative de chambre (10) qui sont conçues pour venir en prise l'une avec l'autre. La tête rotative de piston (40) comprend cinq pistons incurvés (41, 42, 43, 44 et 45) agencés autour de son périmètre. La tête rotative de chambre (10) comprend cinq chambres (11, 12, 13, 14 et 15) agencées autour de son périmètre. Le moteur comprend en outre des orifices d'admission d'air frais (5, 6, 7 et 8) et de récupération des gaz d'échappement (57 et 58), des injecteurs de carburant (9) et une configuration d'allumage du carburant.
