Abstract

Le moteur comporte une chambre de combustion présentant un col rétréci, prévue pour communiquer à l'air un mouvement tourbillonnaire, et où le combustible est injecté dans l'air en mouvement pour former un film sur la paroi de la chambre, où est utilisé un injecteur dans lequel l'organe de commande, dans la plage inférieure de régime et/ou de charge du moteur, ne libère qu'un seul ou quelques trous d'injection, et dans la plage supérieure de régime et/ou de charge libère un deuxième ou un nombre supplémentaire de trous d'injection, où le rapport entre le diamètre le plus grand de la chambre de combustion et le diamètre de son col se situe entre 1,05 et 1,25, où la fréquence de rotation de l'air se situe entre 135 et 185 Hz, et où la durée d'injection, à pleine charge, s'étend sur plus de 20 degrés de rotation de vilebrequin. Par une meilleure combustion en bas régime on évite l'émission de fumée bleue nocive.The engine has a combustion chamber with a narrowed neck, designed to impart a swirling motion to the air, and where fuel is injected into the moving air to form a film on the wall of the chamber, where a fuel is used. injector in which the control member, in the lower range of engine speed and / or load, releases only one or a few injection holes, and in the upper range of engine speed and / or load releases a second or additional number of injection holes, where the ratio of the largest diameter of the combustion chamber to the diameter of its neck is between 1.05 and 1.25, where the frequency of rotation of the air is between 135 and 185 Hz, and where the injection time, at full load, extends over more than 20 degrees of crankshaft rotation. By better combustion at low speed, the emission of harmful blue smoke is avoided.
