Abstract
Description
La présente invention concerne un dispositif pour améliorer le fonctionnement des moteurs à explosion ou à combustion. Cette amélioration est obtenue essentiellement par 1' utilisation d'un accouplement élastique entre l'arbre moteur et le volant d'inertie. The present invention relates to a device for improving the operation of internal combustion or combustion engines. This improvement is essentially obtained by the use of an elastic coupling between the motor shaft and the flywheel.
Traditionnellement le volant d'inertie d'un moteur est relié d'une manière rigide à l'arbre moteur. Traditionally the flywheel of a motor is rigidly connected to the motor shaft.
La figure I représente le diagramme couple-vitesse angulaire d'un moteur normal, 4 cylindres, 4 temps, pour un tour de l'arbre moteur soit 360 O
La courbe (1) représente le couple moteur. L'horizontale (2) représente le couple utile résistant moyen. La courbe (3) représente le couple résistant dû aux cylindres non sollicités et travaillant à l'aspiration, la compression et l'échappement. Cette courbe (7) ajoutée à l'horizontale (2) définit le couple résistant total. La courbe (4) représente les oscillations de la vitesse angulaire du moteur qui sarie entre le minimum (V1) et le maximum (V2).Figure I represents the angular torque-speed diagram of a normal engine, 4 cylinders, 4 times, for one revolution of the engine shaft, i.e. 360 O
Curve (1) represents the engine torque. The horizontal (2) represents the average resistant working torque. The curve (3) represents the resistive torque due to the non-stressed cylinders and working on the suction, compression and exhaust. This curve (7) added to the horizontal (2) defines the total resistive torque. The curve (4) represents the oscillations of the angular speed of the motor which varies between the minimum (V1) and the maximum (V2).
L'examen de la figure 1 permet de faire les deux remarques suivantes sur le fonctionnement d'un moteur traditionnel
to) La vitesse angulaire de 1'arbre moteur diminue à partir du point mort haut correspondant à l'angle OC de la figure 1, pour atteindre le minimum (vit) au moment ou le couple moteur devient supérieur au couple résistant. Ce ralentissement, qui se produit au début de l'explosion dans le cylindre sollicité est contraire à un bon rendement thermodynamique du moteur.The examination of FIG. 1 makes it possible to make the following two remarks on the operation of a traditional motor
to) The angular speed of the motor shaft decreases from the top dead center corresponding to the angle OC of FIG. 1, to reach the minimum (vit) at the moment when the motor torque becomes greater than the resistive torque. This slowdown, which occurs at the start of the explosion in the stressed cylinder, is contrary to good thermodynamic efficiency of the engine.
20) La vitesse angulaire après avoir atteint~le minimum (V1) augmente jusqu'au maximum (V2). Ce maximum (V2) est déphasé de l'angle (*1) par rapport au maximum du couple moteur. Cet angle (*1) est relativement important ce qui est contraire à un bon rendement mécanique du moteur entre les vitesses (V1) et (V2). En effet la puissance fournie par le moteur entre ces vitesses est sensiblement fonction du cosinus de cet angle (91). 20) The angular speed after reaching ~ the minimum (V1) increases to the maximum (V2). This maximum (V2) is out of phase with the angle (* 1) relative to the maximum of the engine torque. This angle (* 1) is relatively large, which is contrary to good mechanical efficiency of the motor between the speeds (V1) and (V2). Indeed, the power supplied by the motor between these speeds is substantially a function of the cosine of this angle (91).
Selon l'invention, L'accouplement élastique entre le moteur et le volant d'inertie permet de remédier à.ces inconvénients. According to the invention, the elastic coupling between the motor and the flywheel overcomes these drawbacks.
La figure 2 représente le diagramme couple-vitesse angulaire du même moteur muni d'un accouplement élastique entre l'arbre moteur et le volant d'inertie. FIG. 2 represents the angular torque-speed diagram of the same motor provided with an elastic coupling between the motor shaft and the flywheel.
Les courbes (1), (2) et (3) sont identiques et font référence à la figure I. La courbe (4) en pointillé représente les oscillations de la vitesse angulaire telles qu'elles se produisent dans un moteur traditionnel. La courbe (5) représente les oscillations de la vitesse angulaire de l'arbre moteur. La courbe (6) représente les oscillations de la vitesse angulaire du volant d'inertie. la zone hachurée (T) correspond à l'énergie emmagasinée par l'accouplement élastique. la zone hachurée (8) correspond à l'énergie restituée par l'accouplement élastique. L'angle 2) correspond au déphasage entre le maximum du couple moteur et le maximum de la vitesse angulaire (V2) de l'arbre moteur. The curves (1), (2) and (3) are identical and refer to Figure I. The curve (4) in dotted lines represents the oscillations of the angular speed as they occur in a traditional motor. The curve (5) represents the oscillations of the angular speed of the motor shaft. The curve (6) represents the oscillations of the angular speed of the flywheel. the hatched area (T) corresponds to the energy stored by the elastic coupling. the hatched area (8) corresponds to the energy restored by the elastic coupling. The angle 2) corresponds to the phase shift between the maximum of the motor torque and the maximum of the angular speed (V2) of the motor shaft.
l'examen de la figure 2 permet de faire les trois remarques suivantes sur le fonctionnement d'un moteur muni d'un accouplement élastique entre l'arbre moteur et le volant d' inertie
10) La vitesse angulaire de l'arbre moteur est plus élevée au début du cycle de l'explosion ce qui entraine une baisse plus rapide de la température dans le cylindre d'où un rendement thermo-dynamigue plus élevé et une pollution plus réduite à l'échappement.the examination of FIG. 2 makes it possible to make the following three remarks on the operation of a motor provided with an elastic coupling between the motor shaft and the flywheel
10) The angular speed of the motor shaft is higher at the start of the explosion cycle, which leads to a faster drop in the temperature in the cylinder, resulting in higher thermodynamic efficiency and less pollution. the exhaust.
20) Le déphasage (T2) entre le maximum du couple moteur et le maximum de la vitesse angulaire de l'arbre moteur est plus petit d'où un rendement mécanique plus élevé entre les vitesses d'oscillation (vol) et (V2). 20) The phase shift (T2) between the maximum of the motor torque and the maximum of the angular speed of the motor shaft is smaller, hence a higher mechanical efficiency between the oscillation speeds (vol) and (V2).
50) L'énergie emmagasinée puis restituée par l'acco;iple- ment élastique contribue à l'amortissement des efforts dûs aux poussées explosives sur les pistons d'où un fonctionnement plus souple du moteur. 50) The energy stored and then returned by the elastic coupling contributes to the damping of the forces due to explosive thrusts on the pistons, hence a more flexible operation of the engine.
La réalisation de l'accouplement élastique est obtenue d'une façon générale par un moyen élastique placé entre l'arbre moteur et le volant d'inertie. La figure 5 représente le principe de cette réalisation générale
Un moteur à explosion ou à combustion interne (4) entraine une machine ou un véhicule (5). Le volant d'inertie (2) assure la régularité du fonctionnement du moteur. L'arbre moteur (1) est. rez au volant d'inertie (2) par l'intermédiaire d'un accouplement élastique (3). La liaison du moteur (4) à la machine (5) se fait. par un moyen traditionnel : embrayage ou accouplement (6). Cette liaison peut être faite sur le volant d'inertie (figure 3) ou sur l'arbreXmoteur. The realization of the elastic coupling is generally obtained by an elastic means placed between the motor shaft and the flywheel. Figure 5 shows the principle of this general realization
An internal combustion or internal combustion engine (4) drives a machine or a vehicle (5). The flywheel (2) ensures the smooth running of the engine. The motor shaft (1) is. ground the flywheel (2) by means of an elastic coupling (3). The connection of the motor (4) to the machine (5) is made. by traditional means: clutch or coupling (6). This connection can be made on the flywheel (Figure 3) or on the motor shaft.
Le moyen élastique constituant l'accouplement' doit per- mettre une amplitude d'oscillation suffisante entre l'arbre moteur et le volant d'inertie. Cette amplitude d'oscillation est déterminée en fonction des caractéristiques du moteur. The elastic means constituting the coupling must allow sufficient amplitude of oscillation between the motor shaft and the flywheel. This amplitude of oscillation is determined according to the characteristics of the motor.
D'une façan générale le moyen élastique utilisé peut être réalisé de différentes façons :
10 Avec des ressorts métalliques dont la forme peut varier et revêtir divers aspects : ressarta. à boudin ou à la- me, simples ou multiples, de section uniforme ou progressive.In general, the elastic means used can be produced in different ways:
10 With metal springs whose shape can vary and take on various aspects: ressarta. rod or blade, single or multiple, of uniform or progressive section.
20 Avec des matériaux fonctionnant par élasticité de masse : caoutchouc, matière plastique naturelle ou synthé- tique, homogène ou hétérogène. 20 With materials operating by mass elasticity: rubber, natural or synthetic plastic, homogeneous or heterogeneous.
70 Avec un système pneumatique. 70 With a pneumatic system.
le moyen élastique peut être réparti sur la circonférence de l'arbre moteurs en un ou plusieurs éléments, d'une manière symétrique ou dissymétrique, axiale, radiale ou autre. the elastic means can be distributed over the circumference of the drive shaft in one or more elements, in a symmetrical or asymmetrical, axial, radial or other manner.
La figure (4) représente le principe d'une réalisation en (1) l'arbre moteur, en (2) le volant d'inertie, en (3) un élément du moyen élastique permettant les oscillations entre li'arbre moteur et le volant d'inertie. Dans cette figure lemoyen élastique est composé de s éléments répartis autour de l'arbre moteur. FIG.
