Description
La présente invention est relative aux carburateurs pour moteurs à combustion interne du genre de ceux qui comportent un système de jaillissement de combustible débouchant dans le conduit d'admission et comprenant un puits d'émulsion alimenté en air et en combustible et un dispositif destiné à corriger la richesse du mélange air/combustible fourni au moteur en fonction de l'amplitude de la composante alternative de pression que fait apparaitre, dans le conduit d'admission, l'aspiration par les cylindres du moteur, qui s'effectue de façon pulsée.The present invention relates to carburetors for internal combustion engines of the type which include a fuel spouting system opening into the intake duct and comprising an emulsion well supplied with air and fuel and a device intended to correct the richness of the air / fuel mixture supplied to the engine as a function of the amplitude of the alternating pressure component which appears, in the intake duct, the suction by the engine cylinders, which takes place in a pulsed manner.
Par nature, l'admission d'un moteur à explosion à pistons est soumise à un régime pulsatoire dû au mouvement alternatif des pistons ; ce régime pulsatoire est particulièrement marqué sur les moteurs modernes dans lesquels la fermeture des soupapes d'admission s'effectue avec un retard important ; il est également très marqué sur les moteurs comportant un nombre peu élevé de cylindres, comme par exemple les moteurs à deux cylindres à plat, dits "flat-twin". Lorsqu'un tel moteur est soumis à une forte charge, l'organe d'étranglement du carburateur, en amont duquel débouche le système de jaillissement principal de combustible, est largement ouvert, et la dépression pulsée est appliquée directement sur le système de jaillissement de combustible. Il en résulte des anomalies de fonctionnement. En particulier, suivant la configuration géométrique de l'ensemble carburateur-tubulure, dont l'adaptation acoustique est difficilement contrôlable, la richesse du mélange air-combustible fourni au moteur est trop faible ou trop forte.By nature, the admission of a piston internal combustion engine is subjected to a pulsating regime due to the reciprocating movement of the pistons; this pulsating regime is particularly marked on modern engines in which the closing of the intake valves takes place with a significant delay; it is also very marked on engines with a small number of cylinders, such as for example two-cylinder flat engines, called "flat-twin". When such an engine is subjected to a heavy load, the throttle member of the carburetor, upstream of which opens the main fuel spouting system, is widely open, and the pulsed vacuum is applied directly to the spouting system. combustible. This results in operating anomalies. In particular, depending on the geometric configuration of the carburetor-manifold assembly, whose acoustic adaptation is difficult to control, the richness of the air-fuel mixture supplied to the engine is too low or too high.
Différents remèdes ont été proposés pour lutter contre les effets de phénomène pulsatoire. En particulier le brevet français n° 76 18 406, publié sous le n° 2 355 170, décrit un carburateur dans lequel le dispositif correcteur module la pression gazeuse régnant au-dessus du combustible en fonction de la composante alternative de la pression qui lui est appliquée. Ce dispositif, s'il donne des résultats satisfaisants, est d'une mise en oeuvre pratique souvent coûteuse ; en particulier, le mode d'exécution donné à titre d'exemple exige un système de clapets permettant de soumettre une membrane à une pression différentielle fonction de la composante alternative de la pression dans le conduit d'admission.Various remedies have been proposed to combat the effects of the pulsating phenomenon. In particular French Patent No. 76 18 406, published under No. 2 355 170, describes a carburetor in which the correcting device modulates the gas pressure prevailing above the fuel as a function of the alternating component of the pressure applied to it. This device, if it gives satisfactory results, is often costly to implement in practice; in particular, the embodiment given by way of example requires a system of valves making it possible to subject a membrane to a differential pressure which is a function of the alternating component of the pressure in the intake duct.
La présente invention vise à fournir un carburateur muni d'un dispositif répondant mieux que ceux antérieurement connus aux exigences de la pratique, notamment en ce que le dispositif est économique et apporte une correction qui peut être adaptée facilement aux exigences des différents types de moteurs.The present invention aims to provide a carburetor provided with a device which meets the requirements of practice better than those previously known, in particular in that the device is economical and provides a correction which can be easily adapted to the requirements of the different types of engines.
Dans ce but, suivant l'invention, le dispositif correcteur comprend une paroi mobile délimitant une chambre communiquant avec le puits d'émulsion et à laquelle les pulsations dans le conduit d'admission sont appliquées par l'intermédiaire d'un élément d'atténuation, de sorte que le dispositif agit sur la pression régnant dans le puits d'émulsion dans le sens de l'augmentation ou de la diminution de la composante alternative de la pression qui lui est communiquée depuis le débouché, suivant que l'adaptation acoustique de l'ensemble carburateur-tubulure tend à produire aux fortes charges du moteur une richesse excessive ou trop faible du mélange.To this end, according to the invention, the correcting device comprises a movable wall delimiting a chamber communicating with the emulsion well and to which the pulsations in the intake duct are applied by means of an attenuation element , so that the device acts on the pressure prevailing in the emulsion well in the direction of increasing or decreasing the alternating component of the pressure communicated to it from the outlet, depending on whether the acoustic adaptation of the carburetor-manifold assembly tends to produce an excessive or too low richness of the mixture at high engine loads.
Ainsi, on superpose, à l'action directe des pulsations sur le débouché du système de jaillissement, une action indirecte s'exerçant sur le puits d'émulsion et qui " est adaptée aux caractéristiques de l'ensemble carburateur -tubulure.Thus, one superimposes, on the direct action of the pulsations on the outlet of the spouting system, an indirect action exerted on the emulsion well and which "is adapted to the characteristics of the carburetor-nozzle assembly.
Dans un premier mode d'exécution de l'invention, la paroi mobile, telle qu'une membrane,sépare une cavité en une chambre communiquant avec le puits d'émulsion et une autre chambre reliée au venturi du carburateur par un conduit, qui peut être muni d'un passage capillaire de faible section. Une telle disposition renforce l'amplitude de la pulsation transmise au puits d'émulsion en ajoutant l'action du dispositif correcteur à celle s'exerçant à partir du débouché ; on obtient ainsi, toutes choses égales par ailleurs, une tendance à l'appauvrissement du mélange fourni au moteur lorsque les pulsations augmentent d'amplitude, permettant de compenser la tendance à l'enrichissement due à l'ensemble carburateur-tubulure.In a first embodiment of the invention, the movable wall, such as a membrane, separates a cavity into a chamber communicating with the emulsion well and a another chamber connected to the carburetor venturi by a conduit, which can be provided with a capillary passage of small section. Such an arrangement reinforces the amplitude of the pulsation transmitted to the emulsion well by adding the action of the correcting device to that acting from the outlet; there is thus obtained, all other things being equal, a tendency to the depletion of the mixture supplied to the engine when the pulsations increase in amplitude, making it possible to compensate for the tendency to enrichment due to the carburetor-manifold assembly.
Dans un second mode d'exécution, la dite chambre constitue une capacité d'amortissement séparée du tube d'émulsion de combustible placé dans le puits d'émulsion par un orifice calibré d'aération du puits, capacité communiquant avec l'entrée d'air du carburateur par un passage calibré et séparée de l'atmosphère par une paroi déformable ou par une paroi rigide. Cette capacité tend à amortir les pulsations transmises au système de giclage de combustible du carburateur ; toutes choses égales par ailleurs, cette disposition évite un appauvrissement du mélange fourni au moteur.In a second embodiment, said chamber constitutes a damping capacity separated from the fuel emulsion tube placed in the emulsion well by a calibrated orifice for ventilating the well, capacity communicating with the inlet of carburetor air through a calibrated passage separated from the atmosphere by a deformable wall or by a rigid wall. This capacity tends to dampen the pulses transmitted to the fuel jet system of the carburetor; all other things being equal, this arrangement avoids a depletion of the mixture supplied to the engine.
L'invention sera mieux comprise à la lecture de la description qui suit de carburateurs inversés munis de dispositifs de correction constituant des modes particuliers de réalisation de l'invention, donnés à titre d'exemples non limitatifs. La description se réfère aux dessins qui l'accompagnent, dans lesquels :
- - la figure 1 montre schématiquement, en coupe, un carburateur dont l'organe d'étranglement est grand ouvert (ce qui correspond à la pleine charge du moteur) muni d'un dispositif correcteur tendant à appauvrir le mélange fourni au moteur lorsque l'amplitude des pulsations augmente, utilisable lorsque le système carburateur-tubulure est tel que les pulsations tendent à enrichir le mélange ;
- - la figure 2 est une courbe représentative de la variation du débit de combustible Q en fonction du rapport entre l'amplitude Ao de la composante alternative de la pression régnant dans le puits et la valeur moyenne P de la pression dans le conduit d'admission ;
- - la figure 3, similaire à la figure 1, montre schématiquement une variante du dispositif correcteur.
- - Figure 1 shows schematically, in section, a carburetor whose throttle member is wide open (which corresponds to the full load of the engine) fitted with a corrective device tending to deplete the mixture supplied to the engine when the amplitude of the pulsations increases, usable when the carburetor-tubing system is such that the pulsations tend to enrich the mixture;
- - Figure 2 is a curve representative of the variation of the fuel flow rate Q as a function of the ratio between the amplitude Ao of the alternating component of the pressure prevailing in the well and the mean value P of the pressure in the intake duct;
- - Figure 3, similar to Figure 1, schematically shows a variant of the correction device.
Le carburateur inversé représenté en figure 1 comprend un conduit d'admission 1 muni d'un organe d'étranglement 2, constitué par un papillon calé sur un axe 3 actionnable par le conducteur. Le conduit est muni d'une entrée d'air 4 protégée par un filtre d'air (non représenté) et d'un venturi principal 5 dans lequel débouche un système de jaillissement principal d'émulsion air/ combustible, alimenté en combustible par une cuve 6 à niveau cbnstant. La cuve 6 contient un flotteur 7 actionnant un pointeau d'arrivée de combustible (non représenté) de façon à maintenir la surface libre du combustible en permanence à peu près au niveau N.The inverted carburetor shown in FIG. 1 comprises an intake duct 1 provided with a throttling member 2, constituted by a throttle wedged on an axis 3 actuable by the driver. The duct is provided with an
Le système de jaillissement principal représenté comprend : un puits d'émulsion 8 alimenté en combustible par la cuve 6, par l'intermédiaire d'un gicleur principal 9 ; un tube d'émulsion 13, muni dans sa partie basse de perforations 10, plongeant dans le puits 8 pour y prélever du combustible et le mélanger avec de l'air d'émulsion provenant de l'entrée d'air 4 du carburateur et arrivant dans un canal muni d'un orifice calibré 12 ; et un canal 14 prélevant le mélange air-combustible à la partie supérieure du puits 8 et le conduisant jusqu'à l'intérieur d'un venturi secondaire 15 d'où il débouche dans le con- s duit d'admission au voisinage du col du venturi principal 5.The main spouting system shown comprises: an emulsion well 8 supplied with fuel by the
L'invention utilise le fait que les pulsations s'exerçant dans le puits d'émulsion ont sur le débit de combustible une action du genre illustré en figure 2. On voit que le débit Q de combustible varie en sens inverse du rapport Ao/P entre l'amplitude de la composante alternative Ao de la pression et la valeur moyenne P de celle-ci.The invention uses the fact that the pulsations exerted in the emulsion well have an action on the fuel flow of the kind illustrated in FIG. 2. It can be seen that the fuel flow Q varies in opposite direction to the ratio Ao / P between the amplitude of the alternating component Ao of the pressure and the mean value P of this this.
Dans le mode d'exécution montré en figure 1, correspondant au cas d'un ensemble carburateur-tubulure dont l'adaptation acoustique est telle qu'à forte charge du moteur on observe une tendance à enrichissement excessif, le dispositif correcteur doit tendre à un appauvrissement.In the embodiment shown in Figure 1, corresponding to the case of a carburetor-tube assembly whose acoustic adaptation is such that at high engine load there is a tendency to excessive enrichment, the corrective device must tend to a impoverishment.
Pour appauvrir et, par conséquent, diminuer le débit de combustible, il faut augmenter l'amplitude des pulsations régnant dans le puits 8 ; on atteint ce résultat en transmettant dans le puits les pulsations de forte am - plitude régnant dans le venturi 5 par l'intermédiaire d'un conduit 24, d'une chambre 22, d'une membrane 23 constituant paroi mobile et d'une chambre 21.To deplete and, consequently, decrease the fuel flow, it is necessary to increase the amplitude of the pulsations prevailing in the well 8; this is achieved by transmitting in the well the pulsations of high amplitude prevailing in the
Une correction supplémentaire, éventuellement fonction de la vitesse, peut être apportée en disposant un élément d'atténuation ajustable sur le conduit 24 ; cet élément est avantageusement constitué d'un tube capillaire 25 disposé sur le conduit 24 et dont les caractéristiques seront choisies en vue d'une adaptation convenable au carburateur.An additional correction, possibly depending on the speed, can be made by having an adjustable attenuation element on the
Dans la variante de réalisation suivant la figure 3, le dispositif correcteur est prévu pour contrarier l'appauvrissement dû à la transmission des pulsations du débouché dans le venturi 15 au puits 8. Pour cela, on prévoit, au-dessus du tube .d'émulsion 13 et de l'orifice d'aération calibré 12, une capacité d'amortissement 30 comprenant deux chambres 31 et 32 séparées l'une de l'autre par une membrane souple 33 ; la chambre 31, en relation directe avec le système de giclage, communique avec l'entrée d'air 4 du carburateur par un passage calibré 34 ; la chambre 32 est reliée à une zone à pression atmosphérique, par un passage 35.In the alternative embodiment according to FIG. 3, the correcting device is provided to counter the depletion due to the transmission of pulses from the outlet in the
En variante, la membrane souple peut être remplacée par une paroi mobile ; en ce cas, la capacité 30 se réduit a la chambre 31.Alternatively, the flexible membrane can be replaced by a movable wall; in this case, the
La capacité atténue l'amplitude des pulsations transmises dans le puits d'émulsion ; ce résultat peut être obtenu avec une petite capacité du fait de la faible célérité acoustique. On a donc bien, comme on l'a vu par les résultats montrés sur la figure 2, une augmentation du débit de combustible par rapport à celui qui interviendrait en l'absence du dispositif. Pour un dimensionnement convenable du gicleur 9 et de l'orifice 12, il peut y avoir un enrichissement compensant au moins partiellement l'appauvrissement dû à l'adaptation acoustique de l'ensemble carburateur-tubulure.The capacity attenuates the amplitude of the pulses transmitted in the emulsion well; this result can be obtained with a small capacity due to the low acoustic speed. We therefore have, as we have seen from the results shown in FIG. 2, an increase in the fuel flow rate compared to that which would occur in the absence of the device. For a suitable dimensioning of the
