Abstract

Device allowing the state of wear of engine oil to be indicated in order to be able to change it in time; which allows the lifetime of an engine to be extended considerably. This system includes two parts: - A probe replacing the original drainage plug. - An ammeter situated on the dashboard.

Description

La présente invention concerne un dispositif ayant la particularité d'indiquer l'etat d'usure de l'huile d'un moteur afin de pouvoir la remplacer à temps, ce qui permet de prolonger considérablement la vie d'un moteur. The present invention relates to a device having the particularity of indicating the state of wear of the engine oil in order to be able to replace it in time, which makes it possible to considerably extend the life of an engine.

Le remplacement de l'huile du moteur d'un véhicule automobile doit s'effectuer selon le kilométrage préconisé par le constructeur, mais ce remplacement peut être négligé ou ne pas être effectué à temps, ce qui serait susceptible de nuire à l'intégrité du moteur et à son bon fonctionnement. The replacement of engine oil in a motor vehicle must be done according to the mileage recommended by the manufacturer, but this replacement may be neglected or not carried out in time, which could damage the integrity of the engine. engine and its proper functioning.

Le dispositif selon l'invention permet de visualiser sur un cadran l'état de l'huile et d'en avertir ainsi l'utilisateur qui devra procéder au remplacement. The device according to the invention makes it possible to display the condition of the oil on a dial and thus to warn the user thereof, who will have to proceed with the replacement.

Ce système comporte deux parties
- Une sonde (figure 1) remplaçant le bouchon de vidange d'origine.This system has two parts
- A probe (figure 1) replacing the original drain plug.

- Un ampèremètre situé sur le tableau du bord du véhicule (figure 2). - An ammeter located on the dashboard of the vehicle (Figure 2).

La sonde est composée d'une cellule photoconductrice (2) et d'une diode électroluminescente (5mm jaune) (3) située à environ 1 mm au-dessus de celle-ci.The probe consists of a photoconductive cell (2) and a light-emitting diode (5mm yellow) (3) located about 1 mm above it.

L'huile circule entre la diode électroluminescente et la cellule qu'elle influence suivant la variation de l'éclairage émis par la diode électroluminescente et traversant cette huile. Les renseignements fournis par la cellule sont transmis par l'intermédiaire de fils électriques (4) à l'ampèremètre (5). Une résistance variable (11) permet de régler et d'adapter cet ampèremètre à chaque type d'huile.The oil circulates between the light-emitting diode and the cell which it influences according to the variation of the lighting emitted by the light-emitting diode and passing through this oil. The information supplied by the cell is transmitted via electrical wires (4) to the ammeter (5). A variable resistance (11) makes it possible to adjust and adapt this ammeter to each type of oil.

Le signal est amplifié par un transistor (6) ; le transistor (7) et les résistances (8) (9) stabilisent le fonctionnement du système lorsque le premier transistor est influencé par la température ambiante.The signal is amplified by a transistor (6); the transistor (7) and the resistors (8) (9) stabilize the operation of the system when the first transistor is influenced by the ambient temperature.

La résistance (10) est intercalée entre le pêle + et la diode électroluminescente de la sonde afin d'adapter un voltage convenable. The resistor (10) is interposed between the + bolt and the light-emitting diode of the probe in order to adapt a suitable voltage.

Quand l'huile du moteur est en bon état, la cellule photoconductrice éclairée par la diode électroluminescente n'offre qu'une faible résistance et l'aiguille de l'ampèremètre se situe à droite du cadran. Par contre quand l'huile est usagée, la cellule est moins ou même plus du tout éclairée ; sa résistance est plus grande et l'aiguille de l'ampèremètre est alors déviée vers le milieu ou la gauche du cadran selon le degré d'usure de l'huile. When the engine oil is in good condition, the photoconductive cell lit by the light-emitting diode offers only a low resistance and the ammeter needle is located to the right of the dial. On the other hand when the oil is used, the cell is less or even more at all lit; its resistance is greater and the needle of the ammeter is then deflected towards the middle or the left of the dial according to the degree of wear of the oil.

Il est bien entendu que la présente invention n'est pas limitée au mode de réalisation décrit et présenté. Elle consistue seulement un exemple auquel de nombreuses modifications peuvent être apportées sans que l'on s'écarte du principe de la présente invention.  It is understood that the present invention is not limited to the embodiment described and presented. It consists only of an example to which numerous modifications can be made without departing from the principle of the present invention.
