Description

  

      llloteur    à combustion interne.    L'objet de la présente invention est un  moteur à combustion interne, à injection du  combustible. Ce moteur est caractérisé en ce  qu'il présente une chambre de combustion  formée par un évidement ménagé dans le pis  ton et dont l'ouverture est disposée excentri  quement par rapport à l'axe du piston, et un  injecteur à axe incliné qui débite du combus  tible en plusieurs jets dans cette chambre de  combustion, l'un des jets de combustible étant  dirigé suivant l'axe de l'injecteur et d'autres  jets étant dirigés transversalement à cet axe.  



  Le dessin représente, à titre d'exemple,  une forme d'exécution de l'objet de l'inven  tion.  



  La     fig.    1 est une vue partielle en coupe  verticale axiale de ce moteur, et la     fig.    2 est  une vue en plan du piston de ce moteur.  



  Le moteur     représenté    comprend le cylin  dre 1, le piston 2 et la culasse 3. 4 désigne la  chambre de combustion, formée par un évide  ment ménagé dans la partie supérieure du  piston. Cette chambre a une forme de révolu  tion d'axe parallèle à celui du piston et elle    est disposée     excentriquement    par rapport à  cet axe. L'entrée de cette chambre de com  bustion a un diamètre inférieur au plus  grand diamètre de la chambre, le rapport  entre le diamètre de     l'entrée    et le plus grand  diamètre de la chambre étant, dans l'exemple  représenté, 1 : 1,5. Dans la culasse 3 est dis  posé l'injecteur 5, dont l'axe est fortement  incliné par rapport à l'axe du cylindre.

   L'ex  trémité de l'injecteur se trouve en dehors de  l'axe du cylindre et elle est également dépla  cée latéralement par rapport à l'axe de la  chambre de combustion 4. La buse de l'in  jecteur est agencée de façon à débiter plu  sieurs jets de     combustible    dans la chambre  de     combustion,    l'un des jets étant dirigé dans  le prolongement de l'axe de l'injecteur, et  plusieurs autres jets étant dirigés transversa  lement à cet axe: De cette     façon    le combus  tible injecté est uniformément réparti dans  l'espace limité par la paroi de la chambre de  combustion. Les calibres des différents trous  d'injection peuvent être choisis de façon que  les doses de combustible fournies par chaque      jet soient égales, ou de façon que ces doses  soient inégales.

    



  Les centres des lumières d'admission et  d'échappement 6 et 7 sont déplacés vers le  côté de la. culasse opposé à celui sur lequel  est monté l'injecteur. Le canal d'échappement  8 est incliné en sens opposé. par rapport à  l'injecteur. L'injecteur se trouve ainsi éloigné  des parois chaudes de ce canal.

   La subdivi  sion de l'injection en un jet axial et plusieurs  jets transversaux donne la possibilité de ré  partir le combustible dans tout l'espace d'une  chambre de combustion de n'importe quelle  forme, tout en permettant de donner à l'injec  teur une position plus inclinée que dans le  cas des dispositions connues de ce genre de  moteur à.     combustion.        Cette    possibilité de  donner à l'injecteur une position très incli  née permet, dans le cas, par exemple,     oii     l'échappement se fait par un canal ménagé  dans la culasse, de l'éloigner plus facilement  des parties surchauffées par l'échappement  que dans le cas des dispositions connues.



      Internal combustion engine. The object of the present invention is an internal combustion engine, with fuel injection. This engine is characterized in that it has a combustion chamber formed by a recess made in the bead and whose opening is disposed eccentrically with respect to the axis of the piston, and an inclined axis injector which delivers fuel. fuel in several jets in this combustion chamber, one of the fuel jets being directed along the axis of the injector and other jets being directed transversely to this axis.



  The drawing represents, by way of example, an embodiment of the object of the invention.



  Fig. 1 is a partial view in axial vertical section of this motor, and FIG. 2 is a plan view of the piston of this engine.



  The engine shown comprises the cylinder dre 1, the piston 2 and the cylinder head 3. 4 designates the combustion chamber, formed by a recess formed in the upper part of the piston. This chamber has a form of revolution with an axis parallel to that of the piston and it is disposed eccentrically with respect to this axis. The inlet of this combustion chamber has a diameter smaller than the largest diameter of the chamber, the ratio between the diameter of the inlet and the largest diameter of the chamber being, in the example shown, 1: 1, 5. In the cylinder head 3 is placed the injector 5, the axis of which is strongly inclined with respect to the axis of the cylinder.

   The tip of the injector is outside the axis of the cylinder and it is also displaced laterally with respect to the axis of the combustion chamber 4. The nozzle of the injector is arranged so as to deliver several jets of fuel into the combustion chamber, one of the jets being directed in the extension of the axis of the injector, and several other jets being directed transversely to this axis: In this way the fuel injected is evenly distributed in the space limited by the wall of the combustion chamber. The sizes of the different injection holes can be chosen so that the doses of fuel supplied by each jet are equal, or so that these doses are unequal.

    



  The centers of the intake and exhaust ports 6 and 7 are moved to the side of the. cylinder head opposite to that on which the injector is mounted. The exhaust channel 8 is inclined in the opposite direction. relative to the injector. The injector is thus located away from the hot walls of this channel.

   The subdivision of the injection into an axial jet and several transverse jets gives the possibility of re-leaving the fuel throughout the space of a combustion chamber of any shape, while allowing the injection to be injected. teur a more inclined position than in the case of the known arrangements of this type of motor. combustion. This possibility of giving the injector a very inclined position makes it possible, in the case, for example, where the exhaust takes place through a channel formed in the cylinder head, to move it away more easily from the parts overheated by the exhaust than in the case of known provisions.
