Abstract

The present invention relates to a device intended to increase the performance of a 4-stroke four cylinder engine with a firing order 1-3-4-2, whilst reducing the effects of pollution by direct injection of part of the burnt gases into the cylinder filled with fresh gases before compression. The self-supercharging engine according to the invention comprises two communication circuits 6 and 7 between orifices pierced at bottom dead centre respectively of cylinders 1 and 4, and, 2 and 3 and passing through valves 8 and 9 for adjusting and regulating the gas flow rates. A shut-off 12 is provided on each piston and rubs on the wall of the corresponding cylinder.

Description

DESCRIPTION
La présente invention concerne un dispositif destiné à augmenter le rendement d'un moteur à 4 temps de 4 cylindres avec ordre d'allumage 1 - 3 - 4 - 2, de conception traditionnelle, tout en diminuant les effets de la pollution.DESCRIPTION
The present invention relates to a device intended to increase the efficiency of a 4-stroke 4-cylinder engine with ignition order 1 - 3 - 4 - 2, of traditional design, while reducing the effects of pollution.

Le moteur à 4 temps traditionnel perd une énergie considérable lors de l'évacuation des gaz d'échappement. Le dispositif objet de l'invention permet de remédier à cet inconvénient en injectant directement une partie des gaz brûlés dans le cylindre rempli de gaz frais avant compression. The traditional 4-stroke engine loses considerable energy during the evacuation of exhaust gases. The device which is the subject of the invention overcomes this drawback by directly injecting part of the burnt gas into the cylinder filled with fresh gas before compression.

I1 comporte, en effet, un circuit de communication des gaz muni d'une vanne (9) qui relie le cylindre 2 au cylindre 3 (circuit (7) ). De même, le cylindre 1 est relié au cylindre 4 par le même procédé (circuit (6) ). I1 comprises, in fact, a gas communication circuit provided with a valve (9) which connects the cylinder 2 to the cylinder 3 (circuit (7)). Likewise, cylinder 1 is connected to cylinder 4 by the same process (circuit (6)).

Ce circuit étant placé au niveau du point mort bas (5), les gaz d'échappement du cylindre 2 passent dans le cylindre 3 qui se trouve en fin d'admission ; ceci a pour effet d'augmenter le volume des gaz du cylindre 3 et de lui donner une compression supérieure à la normale et un meilleur rendement. This circuit being placed at the bottom dead center (5), the exhaust gases from cylinder 2 pass into cylinder 3 which is at the end of intake; this has the effect of increasing the volume of the gases of cylinder 3 and giving it a compression greater than normal and a better yield.

Le même effet se produit dans le cas inverse, c'est-àdire, lorsque le piston 3 alimente le piston 2. Le même résultat est obtenu lorsque le cylindre 1 alimente le cylindre 4, puis lorsque, à son tour, le cylindre 4 alimente le cylindre 1. The same effect occurs in the opposite case, that is to say, when the piston 3 supplies the piston 2. The same result is obtained when the cylinder 1 supplies the cylinder 4, then when, in turn, the cylinder 4 supplies cylinder 1.

Les vannes (8) et (9) jouent le rôle de régulateur de débit des gaz et agissent sur la compression qu'on peut augmenter ou diminuer à la volonté du régleur qui recherche le meilleur rendement. The valves (8) and (9) play the role of gas flow regulator and act on the compression which can be increased or decreased at the will of the regulator who seeks the best efficiency.

Ce circuit est destiné à être en contact permament avec les gaz chauds oxydants et doit être réalisé en acier inoxydable et brasé sur les cylindres percés au préalable au niveau du "point mort bas". This circuit is intended to be in permanent contact with the oxidizing hot gases and must be made of stainless steel and brazed on the cylinders drilled beforehand at the "bottom dead center".

Pour éviter une pénétration du lubrifiant des paliers et pistons dans les circuits, un obturateur mobile (12) sera placé sur chaque piston. I1 sera fabriqué en fonte, aura une forme épousant le diamètre du cylindre, sa longueur permettra la fermeture de l'orifice au moment où le piston sera au "point mort haut" et sa largeur sera le double du diamètre de l'orifice. To avoid penetration of the lubricant of the bearings and pistons in the circuits, a mobile shutter (12) will be placed on each piston. I1 will be made of cast iron, will have a shape matching the diameter of the cylinder, its length will allow the orifice to close when the piston is at "top dead center" and its width will be twice the diameter of the orifice.

Un bon fonctionnement sera assuré en réglant l'ouverture de la soupape d'échappement au moment précis où le piston aùra franchi le "point mort bas" vers le haut, au niveau de l'orifice du circuit de communication. Proper operation will be ensured by adjusting the opening of the exhaust valve at the precise moment when the piston has crossed the "bottom dead center" upwards, at the orifice of the communication circuit.

AVANTAGES
De conception simple, ce système permet de réaliser des performances supérieures à celles du moteur normal tout en réduisant la consommation de carburant et en diminuant la pollution, puisque une partie des gaz d'échappement passent deux fois dans les chambres d'explosion. BENEFITS
Simple in design, this system achieves higher performance than the normal engine while reducing fuel consumption and reducing pollution, since part of the exhaust gases pass twice through the explosion chambers.
