Abstract
Description
La présente invention concerne un dispositif empêchant tous problème deThe present invention relates to a device preventing any problem of
surchauffe, voire de détérioration, de culasse sur les moteurs thermiques. overheating or even deterioration of the cylinder head on the engines.
D'après la fabrication originelle de ce type de moteurs, il est courant de trouver des systèmes de contrôle concernant le circuit d'huile et,ou, d'eau et pourtant la rupture du joint de culasse reste une panne fréquente. According to the original manufacture of this type of engine, it is common to find control systems for the oil circuit and / or water and yet the rupture of the cylinder head gasket remains a frequent failure.
Le dispositif selon l'invention permet d'anticiper cette panne. The device according to the invention makes it possible to anticipate this failure.
La présente invention consiste en un dispositif pour stopper ou empêcher le fonctionnement d'un moteur thermique en cas de surchauffe de culasse. Il comporte, d'une part, un circuit électrique connecté sur celui d'origine du thermo-contact d'eau, composé d'un relais temporisé empêchant le fonctionnement moteur et d'un relais annexe signalant le défaut et, d'autre part, d'un circuit électrique connecté sur celui d'origine du mano-contact d'huile composé d'un relais temporisé empêchant le fonctionnement moteur et d'un relais annexe signalant le défaut. The present invention consists of a device for stopping or preventing the operation of a heat engine in the event of overheating of the cylinder head. It comprises, on the one hand, an electrical circuit connected to the original one of the water thermo-contact, composed of a timed relay preventing engine operation and an auxiliary relay signaling the fault and secondly , an electrical circuit connected to that of the original oil pressure switch consisting of a timed relay preventing engine operation and an auxiliary relay signaling the fault.
On trouvera de plus, non prévu d'origine, un thermostat fixé sur la culasse par 20 bi-métal ou cavalier. In addition, not originally provided, a thermostat mounted on the cylinder head by bi-metal or rider.
Ce dispositif comporte en effet selon une première caractéristique un circuit électrique se connectant sur celui d'origine des commandes. Une fois un défaut constaté, le circuit d'origine déclenche le témoin correspondant et le circuit rajouté active un relais. Ce même appareil contrôle le système d' anti-démarrage qui se temporise et empêche toute mise en route tant que les conditions de marche normale ne sont pas requises. This device comprises in fact according to a first characteristic an electrical circuit connecting to the original of the controls. Once a fault is found, the original circuit triggers the corresponding light and the added circuit activates a relay. This same device controls the immobilizer system which delays and prevents start - up until normal operating conditions are required.
Le système à temporisation réglable permet, en présence d'un défaut, d'empêcher le démarrage à froid et, en cas d'utilisation, de signaler qu'il ne reste que x secondes avant l'arrêt du moteur; ce temps dépendant du réglage de la temporisation et des valeurs préconisées par le constructeur. The adjustable delay system allows, in the presence of a fault, to prevent cold start and, if used, to signal that there are only x seconds before the engine stops; this time depends on the setting of the time delay and the values recommended by the manufacturer.
Il est composé d'un relais temporisé Rtl, qui empêche la mise en route du moteur, et d'un relais annexe Tl, qui signale le défaut, connectés au thermo-contact d'eau et au thermostat de culasse ainsi que d'un relais temporisé Rt2, qui empêche la mise en route du moteur, et d'un relais annexe T2, qui signale le défaut, connectés au mano-contact d'huile (figure 1).Tous ces composants se trouveront dans un boîtier étanche, situé à un endroit accessible et propice. It consists of a timed relay Rtl, which prevents the starting of the motor, and an auxiliary relay Tl, which signals the fault, connected to the water thermo-contact and the cylinder head thermostat as well as a Timed relay Rt2, which prevents the motor from starting, and a relay relay T2, which indicates the fault, connected to the oil pressure switch (Figure 1). All these components will be in a waterproof housing, located in an accessible and suitable place.
Une autre caractéristique de ce système consiste en la création dans ledit boîtier d'un anti-démarrage branché sur un thermostat qui sera fixé sur la culasse et préréglé pour une température maximale d'utilisation préconisée par le constructeur et non prévu d'origine. Another feature of this system consists in the creation in said housing of an immobilizer connected to a thermostat that will be fixed on the cylinder head and preset for a maximum use temperature recommended by the manufacturer and not provided original.
Afin de prévenir l'utilisateur que le dispositif de protection est enclenché, un témoin sera disposé à un endroit bien visible. In order to warn the user that the protective device is engaged, a witness will be placed in a conspicuous place.
Les dessins annexés fournissent les indications quant au fonctionnement 50 électrique et aux différents points de branchement sur un moteur. Celui pris comme exemple ne l'est qu'à titre indicatif. The accompanying drawings provide the indications as to the electrical operation and the different points of connection on an engine. The one taken as an example is only indicative.
La figure 1 représente les modifications apportées par rapport au circuit électrique d'origine. Figure 1 shows the modifications made with respect to the original electrical circuit.
La figure 2 représente un bloc-moteur avec le point de prise de données sur le mano-contact d'huile. Figure 2 shows an engine block with the data collection point on the oil pressure switch.
La figure 3 représente un radiateur avec le point de prise de données sur le thermocontact d'eau. Figure 3 shows a radiator with the data taking point on the water thermocontact.
La figure 4 représente une culasse avec le point de prise de données sur le thermostat. Figure 4 shows a cylinder head with the data pick-up point on the thermostat.
La figure 5 représente le boîtier contenant les composants, étanche et placé dans un endroit accessible et propice. Figure 5 shows the housing containing the components, sealed and placed in an accessible and suitable location.
Dans un mode particulier de réalisation, le thermo-contact 1,le témoin 2, le mano-contact 3 et le témoin 4 sont d'origine. Sont rapportés le thermostat 5,fixé par bi-métal ou cavalier, au plus près possible de l'endroit le plus chaud de la culasse, et le témoin 6 ( fonctionnement de l'anti-démarrage), bien visible pour l'utilisateur. In a particular embodiment, the thermo-contact 1, the control 2, the pressure switch 3 and the control 4 are original. Are reported the thermostat 5, fixed by bi-metal or jumper, as close as possible to the hottest part of the cylinder head, and the indicator 6 (operation of the immobilizer), clearly visible to the user.
Prenons l'exemple du problème d'huile où, dans ce cas, le mano-contact 3, figures 1 et 2, actionne Rt2 et T2. De part cette action, le témoin 4 s'allume tout de suite signalant donc qu'il va y avoir un arrêt moteur. Le témoin 6, commandé par le relais temporisé, ne s'allumera qu'au moment de cet arrêt moteur en en indiquant la cause. Take the example of the oil problem where, in this case, the pressure switch 3, FIGS. 1 and 2, actuates Rt2 and T2. Due to this action, the warning light 4 comes on immediately, indicating that there will be an engine stop. The indicator 6, controlled by the timed relay, will only light up at the moment of this engine stop, indicating the cause.
Le niveau d'huile redevenu correct, le mano-contact annule son information, désactivant Rt2,T2 et 6; le moteur peut donc redémarrer. The oil level is again correct, the pressure switch cancels its information, disabling Rt2, T2 and 6; the engine can restart.
Le modèle pris en exemple comporte d'origine un anti-démarrage, mais pour ceux en étant dépourvu, une coupure d'alimentation des bobines agit de la 35 même manière. The exemplary model originally has an immobilizer, but for those without, a power failure of the coils acts in the same way.
Le fonctionnement est identique avec les autres protections: Thermo-contact - Thermostat A titre d'exemple non limitatif, le boîtier étanche aura une dimension de 125 mm de largeur par 135 mm de longueur pour une hauteur de 50 mm. The operation is identical with the other protections: Thermo-contact - Thermostat As a non-limiting example, the sealed housing will have a dimension of 125 mm wide by 135 mm long and a height of 50 mm.
Le dispositif selon l'invention est destiné aux utilisateurs et fabricants de moteurs thermiques. The device according to the invention is intended for users and manufacturers of heat engines.
