Abstract

L'invention concerne un moteur à combustion interne. Ce moteur comporte un ensemble de piston et de cylindre 12c dont le piston 36 comporte une surface centrale circulaire 84 entourée d'une surface annulaire 80 dont elle est séparée par une gorge 86 plus profonde que la course du piston et qui reçoit une paroi cylindrique interne 46 du cylindre 34. Une culasse mobile 40 coopère avec la paroi 46 pour former une chambre d'admission/compression centrale 180 qui communique avec une chambre de détente/échappement annulaire extérieure 80 par des orifices 50 sélectivement masqués ou démasqués par la culasse mobile dont le déplacement règle également le cycle de compression. Le volume maximal de la chambre de détente/échappement est choisi de façon à réduire la pression des produits de combustion à la pression atmosphérique ou à une pression inférieure. La température des gaz d'echappement est également réduite. L'invention permet d'accroître le rendement du cycle thermodynamique.
