Abstract
Description
L'invention concerne un dispositif d'injection, pour moteur à combustion interne, plus particulièrement pour moteur Diesel, utilisant un combustible d'injection principale et un combustible de pré-injection éventuellement différent du combustible d'injection principale.The invention relates to an injection device, for an internal combustion engine, more particularly for a diesel engine, using a main injection fuel and a pre-injection fuel possibly different from the main injection fuel.
L'utilisation dans les moteurs Diesel de combustibles à faible pouvoir d'auto-inflammation (combustible à bas indice de cétane) conduit à remplacer à faible vitesse et faible charge, le combustible à faible pouvoir d'auto inflammation par un combustible dont le pouvoir d'auto-inflammation est supérieur. Ceci a notamment pour inconvénient d'augmenter considérablement les coûts d'exploitation des moteurs.The use in diesel engines of fuels with low self-ignition power (fuel with low cetane number) leads to replacing at low speed and low load, the fuel with low self-ignition power by a fuel whose power auto-ignition is superior. This notably has the drawback of considerably increasing the operating costs of the engines.
Pour remédier à cet inconvénient, on connaît des moteurs équipés d'un dispositif de préinjection d'un combustible à haut pouvoir d'auto-inflammation, la pré-injection étant utilisée dès que les conditions de fonctionnement du moteur ne permettent plus une bonne combustion du combustible à bas indice de cétane. Un tel dispositif est par exemple décrit dans le brevet américain no4612898 qui montre une chambre de combustion avec plusieurs buses pour l'injection d'un combustible principal à faible pouvoir d'auto-inflammation et une buse supplémentaire pour l'injection d'un combustible à haut pouvoir d'auto-inflammation. Néanmmoins la plage de fonctionnement avec du combustible à faible pouvoir d'auto-inflammation garantie par les systèmes connus actuellement reste insuffisante.To overcome this drawback, engines are known which are equipped with a device for pre-injecting a fuel with high self-ignition power, pre-injection being used as soon as the operating conditions of the engine no longer allow good combustion. low cetane number fuel. Such a device is for example described in U.S. Patent No. 4612898 which shows a combustion chamber with a plurality of nozzles for injecting a main fuel low power Autoignition and an additional nozzle for injection a fuel with high self-ignition power. Nevertheless, the operating range with fuel with low self-ignition power guaranteed by the systems known at present remains insufficient.
Le problème peut se poser de la manière suivante :
Le fonctionnement du moteur à forte charge, avec un combustible à faible pouvoir d'auto-inflammation mais relativement bon marché, est satisfaisante.The problem can arise as follows:
The operation of the engine at high load, with a fuel with low self-ignition power but relatively inexpensive, is satisfactory.
Si la charge du moteur diminue progressivement, il arrive au moment où une bonne combustion nécessite l'injection additionnelle d'un carburant à haut pouvoir d'auto-inflammation, mais cher.If the engine load gradually decreases, it comes at a time when good combustion requires the additional injection of a fuel with high self-ignition power, but expensive.
Un but de l'invention est de réaliser un dispositif d'injection dans lequel on peut "retarder" au maximum l'instant où il est nécessaire d'utiliser en pré-injection un combustible à haut pouvoir d'auto-inflammation, la quantité de combustible de pré-injection devant être aussi faible que possible pour des raisons économiques. Le but de la présente invention est de proposer un dispositif d'injection qui permette le fonctionnement du moteur avec un combustible à faible pouvoir d'auto-inflammation à l'intérieur d'une plage plus étendue.An object of the invention is to provide an injection device in which one can "delay" as much as possible the instant when it It is necessary to use a pre-injection fuel with high self-ignition power, the amount of pre-injection fuel should be as low as possible for economic reasons. The object of the present invention is to provide an injection device which allows the engine to operate with a fuel with low self-ignition power within a wider range.
L'invention a pour objet un dispositif d'injection de combustible pour moteur à combustion interne, notamment pour moteur Diesel, du type comportant deux pulvérisateurs réunis dans un même corps ou situés dans des corps séparés, l'un servant à la pré-injection de combustible, l'autre à l'injection principale de combustible, les combustibles étant différents ou non, lesdits pulvérisateurs étant situés à proximité l'un de l'autre au voisinage du centre de la culasse, munis de trous de pulvérisation de combustible équidistants ou non et contrôlés par des aiguilles distinctes, caractérisé en ce que le pulvérisateur de pré-injection comporte une série de trous dont les axes s'appuient sur un premier cône et le pulvérisateur d'injection principale comporte une série de trous dont le nombre est le double de celui du pulvérisateur de pré-injection et dont les axes s'appuient sur un second cône, la position relative des cônes, l'angle de chacun des cônes et l'orientation des axes des trous sur les cônes étant choisis de telle sorte que, dans une zone située sensiblement à mi-longueur des jets d'injection principale, les distances entre chacun des jets de pré-injection et les deux jets d'injection principale associés soient minimales et sensiblement égales.The subject of the invention is a fuel injection device for an internal combustion engine, in particular for a diesel engine, of the type comprising two sprayers united in the same body or located in separate bodies, one used for pre-injection. of fuel, the other at the main fuel injection, the fuels being different or not, said sprayers being located close to each other in the vicinity of the center of the cylinder head, provided with equidistant fuel spray holes or not and controlled by separate needles, characterized in that the pre-injection sprayer has a series of holes whose axes rest on a first cone and the main injection sprayer has a series of holes whose number is double that of the pre-injection sprayer and whose axes are supported by a second cone, the relative position of the cones, the angle of each cone and the o orientation of the axes of the holes on the cones being chosen such that, in an area located substantially mid-length of the main injection jets, the distances between each of the pre-injection jets and the two associated main injection jets are minimal and substantially equal.
Selon une autre caractéristique de l'invention, les trous du pulvérisateur de pré-injection comportent, dans le sens de l'écoulement du combustible, une partie cylindrique et une partie tronconique, l'évasement de la partie tronconique étant situé côté chambre de combustion, et la longueur de la partie conique étant inférieure à 80 % de l'épaisseur de la paroi.According to another characteristic of the invention, the holes of the pre-injection sprayer comprise, in the direction of the flow of the fuel, a cylindrical part and a frustoconical part, the flaring of the frustoconical part being situated on the combustion chamber side. , and the length of the conical part being less than 80% of the thickness of the wall.
L'invention sera mieux comprise à l'aide de la description et des figures qui vont suivre.The invention will be better understood with the aid of the description and the figures which follow.
La figure 1 est un schéma illustrant la répartition des jets de pré-injection et d'injection principale à l'intérieur de la chambre de combustion.FIG. 1 is a diagram illustrating the distribution of the pre-injection and main injection jets inside the combustion chamber.
La figure 2 est une vue schématique en perspective illustrant la disposition relative des jets principaux et des jets de pré-injection.Figure 2 is a schematic perspective view illustrating the relative arrangement of the main jets and the pre-injection jets.
La figure 3 montre une coupe partielle du pulvérisateur de pré-injection.Figure 3 shows a partial section of the pre-injection sprayer.
La figure 1 montre une demie coupe transversale de la chambre de combustion (1) d'un moteur à combustion interne équipé du dispositif selon l'invention. Au voisinage du centre de la chambre de combustion sont représentés schématiquement un pulvérisateur d'injection principale (2) et un pulvérisateur de pré-injection (3). Le pulvérisateur d'injection principale est muni d'une série de trous d'axe (4a, 5a, 6a, 7a) équidistants d'un angle (A) et le pulvérisateur de pré-injection est muni d'une série de trous d'axe (8a, 9a) équidistants d'un angle (B). Le nombre de trous du pulvérisateur d'injection principale est double de celui du pulvérisateur de pré-injection.Figure 1 shows a half cross section of the combustion chamber (1) of an internal combustion engine equipped with the device according to the invention. In the vicinity of the center of the combustion chamber are shown schematically a main injection sprayer (2) and a pre-injection sprayer (3). The main injection sprayer is provided with a series of axis holes (4a, 5a, 6a, 7a) equidistant from an angle (A) and the pre-injection sprayer is provided with a series of holes d axis (8a, 9a) equidistant from an angle (B). The number of holes in the main injection sprayer is twice that of the pre-injection sprayer.
Lors du fonctionnement, le combustible est injecté sous forme de jets schématisés en (4b, 5b, 6b 7b) pour l'injection principale et en (8b, 9b) pour la pré-injection. L'orientation relative des deux ensembles de trous ainsi que l'angle des cônes sur lesquels s'appuient les axes des trous sont choisis de façon à minimiser la distance entre les jets (8b) et (9b) et les zones (4c), (5c), (6c) et (7c) situées sensiblement à mi-longueur des jets d'injection principale, comme on peut le voir dans la figure 2.During operation, the fuel is injected in the form of jets shown diagrammatically in (4b, 5b,
Suivant les dimensions de la chambre de combustion, il peut être intéressant d'augmenter ou de diminuer le nombre de trous de pulvérisation, tout en conservant un rapport de 1/2 entre les trous de pré-injection et les trous d'injection principale.Depending on the dimensions of the combustion chamber, it may be advantageous to increase or decrease the number of spray holes, while maintaining a ratio of 1/2 between the pre-injection holes and the main injection holes.
La figure 3 montre une coupe partielle de la paroi du pulvérisateur de pré-injection au droit du trou d'axe (8a). Selon l'invention le trou est constitué de deux parties, une partie cylindrique (10) suivie, dans le sens de l'écoulement du combustible, d'une partie conique (11) dont l'évasement est tourné vers la chambre de combustion. La présence de la partie conique permet d'obtenir une meilleure pulvérisation du combustible répartie dans un cône d'angle (C) plus grand que celui qui serait obtenu avec un trou uniquement cylindrique.Figure 3 shows a partial section of the wall of the pre-injection sprayer to the right of the axis hole (8a). According to the invention, the hole consists of two parts, a cylindrical part (10) followed, in the direction of the flow of the fuel, a conical part (11) whose flare is turned towards the combustion chamber. The presence of the conical part makes it possible to obtain a better spraying of the fuel distributed in a cone of angle (C) larger than that which would be obtained with a hole only cylindrical.
La répartition des jets de pré-injection et d'injection principale combinée à l'utilisation de trous de pré-injection tronconiques conformément à l'invention permet d'étendre la plage de fonctionnement avec un combustible unique à faible pouvoir d'auto-inflammation vers les faibles charges et faibles vitesses lorsque celui-ci est utilisé à la fois en pré-injection et en injection principale. Lorsque la limite de fonctionnement avec un combustible unique est atteinte, il convient d'utiliser un combustible de pré-injection à pouvoir d'auto-inflammation élevé.The distribution of the pre-injection and main injection jets combined with the use of frustoconical pre-injection holes in accordance with the invention makes it possible to extend the operating range with a single fuel with low self-ignition power. towards low loads and low speeds when this is used for both pre-injection and main injection. When the operating limit with a single fuel is reached, a pre-injection fuel with high self-ignition power should be used.
Pour l'injection, on utilise de préférence deux pulvérisateurs réunis dans un même corps, connu par exemple par le brevet américain no 4524737.For injection, preferably two sprayers are used together in the same body, known for example by US Patent No. 4,524,737.
