Abstract

Moteur alimenté en hydrogène à combustion interne à quatre temps alternatif allumé comprenant un carter de moteur (10), un vilebrequin (20) pouvant tourner autour d'un axe de vilebrequin, un cylindre (30) agencé à l'intérieur dudit carter de moteur (10), un piston (35) agencé à l'intérieur dudit cylindre pour réaliser un mouvement de va-et-vient le long d'un axe de va-et-vient entre une position de point mort haut (TDC) distale par rapport audit vilebrequin (20) et une position de point mort bas (BDC) proximale par rapport audit vilebrequin (20) et fonctionnellement relié au vilebrequin de sorte que le piston alternatif (35) communique un mouvement de rotation au vilebrequin (20), une chambre de combustion (37) définie à l'intérieur dudit cylindre (30) entre le carter de moteur (10) et une tête du piston (35) opposée audit vilebrequin (20), une soupape d'admission (40.1), une soupape d'échappement (45.1), un injecteur d'hydrogène (60) configuré pour injecter directement de l'hydrogène dans ladite chambre de combustion (37), un injecteur d'eau (70) configuré pour injecter directement de l'eau à l'intérieur de ladite chambre de combustion (37) ; une bougie d'allumage ou une bougie de préchauffage (50), et une unité de commande de moteur configurée pour commander une synchronisation et une quantité d'injection d'hydrogène et d'injection d'eau, ladite unité de commande de moteur étant configurée pour injecter dans la chambre de combustion une première quantité d'hydrogène à un premier instant de 20° avant le TDC pendant une course de compression à 20° après le TDC, pour injecter dans la chambre de combustion une deuxième quantité d'eau à un deuxième instant de 110° à 90° avant le TDC pendant une course de compression et pour injecter dans la chambre de combustion une troisième quantité d'hydrogène à un troisième instant de 180° à 100° avant le TDC pendant une course de compression.
