On connaît déjà les équipements permettant de diagnostiquer l'état d'un moteur, tels que : appareil de mesure des compressions des cylindres, appareil de mesure de la puissance d'un moteur, ou autres appareils de mesure utilisés par les professionnels de la réparation de moteurs à explosion. Cependant, ces appareils constituent des investissements importants qui ne sont pas accessibles à tout le monde, et notamment au grand public. D'autre part, leur mise en oeuvre requiert un temps important, supérieur au temps nécessaire à la mise en oeuvre du présent produit. La présente invention a pour but de résoudre les inconvénients précités et de proposer un produit permettant de diagnostiquer sans outillage et dans un temps limité, le non fonctionnement ou fonctionnement partiel d'un cylindre d'un moteur. Cependant, le présent produit est destiné à produire une indication sur les dysfonctionnements du moteur quelque soit leur origine. Equipment for diagnosing the condition of an engine is already known, such as: cylinder compression measuring apparatus, apparatus for measuring the power of an engine, or other measuring apparatus used by repair professionals explosion engines. However, these devices are important investments that are not accessible to everyone, including the general public. On the other hand, their implementation requires a significant time, greater than the time required to implement the present product. The present invention aims to solve the aforementioned drawbacks and to provide a product for diagnosing without tools and in a limited time, the non-operation or partial operation of a cylinder of a motor. However, this product is intended to provide an indication of engine malfunctions regardless of their origin.
L'identification de l'origine de ces dysfonctionnements nécessite l'emploi d'outillage approprié à l'analyse complète des différents organes du moteur. 2966198 -2- Selon l'invention, tout ou partie des pigments thermo chromiques sont irréversibles, c'est-à-dire que la couleur obtenue suite l'élévation de température, conserve son intensité y compris après baisse de la température à laquelle le pigment est soumis. 5 Les pigments thermo chromiques ont une température de coloration comprise dans la plage préférentielle de coloration débutant au dessus de 70°C pour obtenir une coloration totale dès 110°C. Dans le cas où les pigments thermo chromiques sont initialement incolores, ils se colorent en fonction de l'élévation de la 10 température. Dans le cas où les pigments thermo chromiques sont initialement colorés, ils changent de couleur en fonction de l'élévation de la température. Le support est constitué d'une couche adhésive en matière synthétique ou papier, couché ou non couché, résistant à des 15 températures supérieures à 150°C, et d'un grammage compris entre 40 et 224 grammes par m2. Dans le cas d'une couche adhésive en matière synthétique, elle est à base notamment de polyester, polypropylène, polyéthylène téréphtalate, polychlorure de vinyle. Le support est constitué d'une vignette comportant les pigments thermo chromiques 20 au centre, et la teinte de référence (teinte à atteindre) sur son pourtour. L'atteinte de la couleur de référence est identifiable lorsque l'ensemble de la surface de la vignette présente une seule couleur uniforme. The identification of the origin of these malfunctions requires the use of appropriate tools for the complete analysis of the various engine components. According to the invention, all or part of the thermochromic pigments are irreversible, that is to say that the color obtained following the rise in temperature, retains its intensity even after falling in the temperature at which the pigment is submitted. The thermochromic pigments have a coloring temperature within the preferred color range starting above 70 ° C to obtain a total color from 110 ° C. In the case where the thermochromic pigments are initially colorless, they color according to the rise in temperature. In the case where the thermochromic pigments are initially colored, they change color depending on the rise in temperature. The carrier consists of an adhesive layer of synthetic or paper, coated or uncoated, resistant to temperatures above 150 ° C, and a basis weight of between 40 and 224 grams per square meter. In the case of an adhesive layer of synthetic material, it is based in particular on polyester, polypropylene, polyethylene terephthalate, polyvinyl chloride. The support consists of a sticker comprising the thermochromic pigments 20 in the center, and the reference color (hue to be achieved) on its periphery. The attainment of the reference color is identifiable when the entire surface of the vignette has a single uniform color.
25 A cet effet, le présent produit est destiné à être appliqué directement sur chaque tubulure (2) ou collecteur d'échappement ou sur une zone voisine affectée à chaque cylindre du moteur, permettant à l'utilisateur de visualiser les écarts de température correspondant aux différents cylindres. Le dit produit est appliqué 30 manuellement par l'utilisateur sur les tubulures ou collecteur d'échappement (2). Pour produire les résultats escomptés, le produit doit être appliqué suivant la préconisation décrite sur la figure 1. La mise en oeuvre du dit produit est associée à un nuancier de couleurs dédié aux caractéristiques desdits pigments 35 thermo chromiques, et comprend les étapes suivantes : a) mise en place, moteur froid, d'au moins un dispositif sur chaque tubulure (2) ou collecteur d'échappement ou sur une zone voisine affectée à chaque cylindre du 2966198 -3- moteur, en veillant à ce qu'elles soient positionnées à une distance équivalente et proche du bloc moteur, en veillant à ne pas les apposer sur une excroissance de la pièce métallique ; To this end, the present product is intended to be applied directly to each manifold (2) or exhaust manifold or to a neighboring zone assigned to each cylinder of the engine, allowing the user to visualize the temperature differences corresponding to the different cylinders. Said product is applied manually by the user on the manifolds or exhaust manifold (2). In order to produce the desired results, the product must be applied according to the recommendation described in FIG. 1. The use of said product is associated with a color chart dedicated to the characteristics of said thermochromic pigments, and comprises the following steps: ) placing, cold engine, at least one device on each manifold (2) or exhaust manifold or on a neighboring zone assigned to each cylinder of the engine, ensuring that they are positioned at an equivalent distance and close to the engine block, taking care not to affix them to an outgrowth of the metal part;
b) mise en fonctionnement du moteur jusqu'à coloration complète d'au moins un desdits dispositifs (4) par comparaison visuelle avec ledit nuancier de couleurs ou avec la teinte de référence; b) operating the engine until complete staining of at least one of said devices (4) by visual comparison with said color chart or with the reference hue;
c) après arrêt du moteur, détermination visuelle pour chaque cylindre par rapport audit nuancier des couleurs des dispositifs pour identifier et localiser les cylindres ayant un fonctionnement normal (4) (teinte maximale) ou un fonctionnement partiel (3) (teinte intermédiaire) ou un non fonctionnement (5) (aucune coloration ou teinte initiale). c) after stopping the engine, visual determination for each cylinder with respect to said color chart of the devices for identifying and locating cylinders having normal operation (4) (maximum hue) or partial operation (3) (intermediate hue) or non-functioning (5) (no initial coloration or hue).
A titre d'exemple non limitatif, le produit pourra se 20 présenter sous forme de vignettes adhésives de 2 centimètres de longueur et 1,5 centimètre de largeur, comportant la couleur finale sur son pourtour, et le pigment thermo chromique au centre. Les pigments thermo chromiques pourront permettre un début de coloration à une température donnée, pour exemple dès 70°C et un 25 changement complet de couleur lors de l'atteinte de la température maximale, pour exemple 110°C. Les dessins annexés donnés à titre d'exemple non limitatifs illustrent l'invention: La figure 1 représente un exemple de mise en place du 30 produit sur les tubulures d'échappement d'un moteur. La figure 2 représente un exemple de résultat dans le cas d'un cylindre entièrement défaillant et 3 cylindres ayant un même niveau de rendement. La figure 3 représente un exemple de résultat dans le cas 35 d'un cylindre partiellement défaillant et 3 cylindres ayant un même niveau de rendement. 5 10 15 By way of nonlimiting example, the product may be in the form of adhesive stickers of 2 cm in length and 1.5 cm in width, with the final color around its periphery, and the thermochromic pigment in the center. The thermochromic pigments may allow a start of coloring at a given temperature, for example from 70 ° C. and a complete change of color upon reaching the maximum temperature, for example 110 ° C. The accompanying drawings given by way of non-limiting example illustrate the invention: Figure 1 shows an example of placing the product on the exhaust pipes of an engine.
